Sound Wave Transmission Through Surfaces

We are so accustomed to the many sounds audible to us at any given time that we hardly pause to distinguish what we are actually hearing or why. Hearing a combination of sounds around your home, such as the dishwasher running, cars passing by and a neighbor mowing the lawn is so commonplace that it does not generally warrant a second thought. However, there is an intricate science behind sound behavior that explains why we hear certain sounds and with what intensity.

A sound wave is an organized vibration which passes energy from particle to particle through any molecular structure. You hear the voice of someone in the same room speaking to you because the energy travels through the molecules of the air and reaches your ear. Likewise, you perceive sounds from outside such as traffic or a lawn mower because the vibrations produced by these sound sources travel through the molecules of the air and through the structure of your home to deliver a portion of the sound energy to your ears.

In this illustration, when the sound vibrations produced by the neighbor’s lawn mower change mediums, a portion of the sound is reflected off of the outer surface of your home while the remainder transfers through the surface and becomes audible within your home. The energy bouncing off of your home and remaining outside is sound reflection, while the energy traveling through the structure and into your home demonstrates sound transmission. Since wood, drywall, concrete and water are made up of molecules, sound energy travels as easily through such structures as it does through air.

Sound transmission can be measured using a metric known as the Sound Transmission Coefficient (STC). The STC rating is a numeric value which describes a wall, floor or ceiling’s propensity to prevent sound transmission. The typical wall with studs and drywall averages an STC rating of 38. A room with an STC rating of 38, for instance, would affect a 38 decibel drop in the audibility of incoming sound in a controlled environment.

While decibels describe the intensity of a sound wave, Hertz is a measure of its frequency, or the number of cycles occurring over a specified time. One Hertz is one vibration, or cycle, per second. Sounds with higher frequencies have a higher pitch. Low frequency sounds, such as bass, have flatter, longer sound waves which travel more easily through surfaces than do higher pitch sounds. Higher frequency sound waves, having a high Hertz value and thus more up and down movement in the cycle, are less successful at traveling through surfaces because they must overcome more distance and time within the structure. Comprehending frequency allows you to better understand why you are able to hear the low pitch lawn mower next door yet you cannot hear the neighbors having a conversation from the same distance.

The behavior of sound waves of differing decibel levels and frequencies accounts for the highly individualized nature of soundproofing and sound reduction projects. It is advised to consult with a reputable soundproofing supplier prior to any soundproofing endeavor so as to ensure that an effective solution for your application is reached.

Increase Traffic on Your Website Using Videos

There is but one perfect place where you can successfully market your services and products and that is the Internet. You can create blogs, web sites, use social web sites or online video marketing to promote yourself or your business more efficiently. Moreover, online video marketing is also a powerful tool for increasing traffic on web sites. As long as you use video editing tools to make your ad appealing, you are on your way to success.

Online video marketing is now one of the most powerful and popular ways of online marketing. For example the videos we see on web sites such as YouTube get millions of views from people all over the world. Therefore if you want to increase traffic on your web site or promote your business, you should definitely consider online video marketing.

However, not all videos draw attention. If you want to make sure that your video gives you credit, then video editing is an extremely important part of the online video marketing plan you make. The purpose of video editing is the removal of parts of the footage you are not pleased with and the arrangement of the video in time, to create the desired footage. By using video editing, you will make sure that your video will draw attention and meet its intended purpose.

Moreover, online video marketing is indeed a powerful tool, but if not used properly it can work to your disadvantage. When your goal is to increase traffic on your web site, promote your products or your services, the video must reach high standards and must be seen by millions of people worldwide.

People often make mistakes that compromise the aspect of their videos. Even if they hire a video editing crew afterwards to try and edit the video themselves, sometimes the only solution is re-shooting the video. If you do not want to get to this point, make sure you are not using improper lightening, you are using a tripod, you are dressed properly or that you are using a teleprompter. These are just few of the mistakes that people often make. If you want to make sure your video will be truly effective, it is best that you seek professional help or advice.

The success of online video marketing also rests on the number of people that watch your video in different areas on the Internet. This means that your video will help you if it is not seen only at video sites, but a link of this video also appears on important search engines. Moreover, for your online video marketing plan to be successful, your video should be seen on all web sites that have content sharing.

Online video marketing refers to more than a well edited video. Although video editing is a crucial part of the plan you make, selling your imagine takes more than that. The video must have keywords that will place your video very high on important search engines.

Online video marketing can be rather difficult if you do not have a little help. From video shooting and editing, to placing the video online, the work and skills required are sometimes beyond your powers. However, with a little help from professionals or with proper information, you can increase the traffic on your web site, you can sell your products and your services better than you have ever imagined.

Measuring the Intensity of Sound – Decibels Explained

The intensity of sound is measured in a unit called the decibel (dB), which describes the relative intensity of a sound based on an algorithmic decibel scale containing values ranging from 0 to 194. Achieving a reduction in decibel levels is a common goal of soundproofing projects, though obtaining an exact measure of the pre-treatment decibel level incurs added cost and is often unnecessary.

Although a zero value on the decibel scale represents the weakest sound audible to humans and sound intensity increases in correspondence with numeric values, the relationship among the values on the decibel scale is not linear but algorithmic. Therefore, the simple assumption that a sound with a 50 dB level is twice as intense as a sound with a 25 dB level would be incorrect. Rather, in a perfect world, each three decibel increment affects a 50% change in sound pressure levels. Thus, a 3 dB drop reduces sound exposure by 50%, while a 6 dB drop reduces exposure by 75%. Though reducing the decibel level produced by a sound source from 80 to 77 may not seem like a major change, it would actually represent a 50% reduction in audible sound.

The intensity of a sound reaching a person’s ear depends not only on the intensity of the sound produced, but also on the person’s distance from the source of the sound. If you were standing one foot away from a loud machine, for instance, you would experience higher decibel level than if you were ten feet away, even though the intensity of the sound produced remains unchanged. This is so because the intensity of sound decreases as sound waves spread out over time and distance, a behavior demonstrated by the Inverse Square Law. The Inverse Square Law is a calculable equation proving that each time the distance between the source of a sound and its recipient doubles, the recipient will experience a 6 dB drop in sound intensity, assuming that no surfaces are present to create reflections that in real world situations would alter these results. Due to the weakening intensity of sound waves with distance, soundproofing and sound reduction treatments in large rooms tend to be more effective than equivalent treatments in smaller areas.

Exposure to high noise levels for extended periods of time can be damaging to the human ear. For this reason, the Occupational Safety & Health Administration standardizes the maximum sound exposure to which employees may be exposed without protection based on the number of hours that they are exposed to the sound source. In effort to keep workplaces free from hazards that can cause employee harm, OSHA requires hearing protection measures to be taken in work environments with decibel levels of 90 and above, with the duration of exposure determining the decibel level at which the standard applies.

To view examples of the decibel levels produced by common commercial, industrial and residential sound sources, view our Decibel Level Comparison Chart.

The Synthesis Methods of Sound

Sound synthesis refers to the creation of interesting sounds using artificial means. The word artificial is referring to the creation of the sound by man. In a sense, sound synthesis has been going on for a long time, and what are considered by many today to be natural instruments are in fact examples of sound synthesis.


Most people consider synthetic sounds to be those produced through the use of electronic devices, and as digital sound synthesis grew of the these techniques, such will be referred to as synthetic sounds. Special sound effects are an important matter associated with sound synthesis because almost all synthesis methods use some sort of wave form as a base and modify it to create the desired sound.


A brief history of sound synthesis methods


One of the earliest devices used in sound synthesis was the tape recorder. The first use of the tape recorder apart from recording was to splice different pieces of composition together. Another early use of the tape recorder was to change the pitch and speed of a recorded piece. This was done by changing the playback speed of the recorded music, although such changes also affected the duration of the recording. After the tape recorder, the next major step in sound synthesis was the use of analog circuits, such as oscillators, op-amps, resistors, capacitors, inductors, and filters to create sounds. One early idea behind many analog synthesis methods was to take a source signal, either a recorded sound or one generated using oscillators, and to filter this signal, perhaps providing a feedback loop to control the generated signal. A variety of filters and envelopes were used to eliminate unwanted harmonics, and to modify the relative amplitudes. The adaptation of digital technology to sound synthesis was the next big step. Digital methods offered advantages over analog methods because of several factors.


Some general points about good synthesis methods


The best methods of synthesis are generally based on tried and true principles. A good synthesizer must have facilities to do what it was designed for. When using a synthesizer in a performance situation, real time control facilities should be paramount.


Sound synthesis methods


Of the many techniques developed for sound synthesis, an important one is FM or frequency modulation. This is because it allows for the generation of a wide variety of sounds, using a small number of parameters. After a suitable starting signal or FM has been generated filters and envelopes are used to take away the unwanted components of a sound while synthesizing sound. The frequency content determines what a synthesis sound will sound like.


An early idea was to take white noise, and filter out all of the unwanted components until only the desired components remain. This method of subtractive sound synthesis proved difficult to do because of limitations of filters.


A much better approach is to generate a sound with the desired components already present, as well as some unwanted components, and to use filters to remove only the unwanted components, as well as to adjust the relative frequency content. The final step in getting realistic sounds using synthesis is to simulate some special effects.


One of the most basic effects is reverberation. Reverberation can be created by adding a time delayed version of the original signal to itself. The relative magnitudes of how the two are mixed determine the amount of reverberation is present.

Surround Sound System Tips

The following article presents the very latest information on surround sound systems. If you have a particular interest in surround sound system, then this informative article is required reading.


If you are in the market for a brand new surround sound system I’m pretty sure you’ve been a little baffled by all the options, bells, whistles, gadgets, gizmos, and price tags on the market today. Trust me, you are not alone. One of the most baffling things to many potential surround sound system consumers is where on earth should you put all the speakers. I intend to answer that question and a few more over the course of the next few paragraphs and hope that you will read along.


The first thing you need to understand is that there are several different types of surround sound systems. The industry standard and most common is the 5.1 channel surround sound system. This set up calls for the use of five speakers plus one subwoofer in addition to the receiver. The five speakers are the front speakers which include a left, right, and center speaker and the left and right surround speakers that are located to the left and right from the rear. You should also have a subwoofer located behind you in order to create the bass notes of sound. The next two types of surround sound systems include the 6.1 channel and 7.1 channel system. The primary differences in these are the addition of one additional speaker for each.


You will be glad to know that most receivers will accommodate the 8 total speakers of a 7.1 channel surround sound system but you may want to check in order to be certain you can upgrade if you chose to buy a 5.1 channel system for the time being. The addition of speakers when you upgrade change the layout of the speakers in your home. The more speakers you have, the greater sound you will enjoy, however, the better the quality of your speakers, the better quality your sound will have. In other words don’t go with lower quality speakers in the beginning in order to have more speakers, as you will be shooting the quality of sound you can experience in the foot. It is better to buy fewer speakers in the beginning and add to your system over time in order to receive better quality.


I trust that what you’ve read so far has been informative. The following section should go a long way toward clearing up any uncertainty that may remain.


When it comes to the placement of the additional speakers if you upgrade to a 6.1 channel surround sound system you will move the speakers currently in the left and right rear to the left and right side and place the new speaker in the center back. If you then upgrade to the 7.1 channel surround sound system you will move the speaker that is in the center to the rear left and place the new speaker to the rear right. This allows you to be literally surrounded by the sound in order to maximize your listening experience.


Of course this is only a recommendation and it is entirely up to you what will work best within your home and according to your tastes and wants in a surround sound system. Not everyone hears music or sound the same and the experience for each will vary greatly from one person to the next. For this reasons it is also a good idea to be sure you have listened to the system in a store before deciding on one and bringing it home. This is a wise decision regardless. I also recommend taking more than one CD or DVD for the listening process in order to make sure the quality is consistent through different mediums.


While the setup of your system is very important to the sound experience it is quite difficult provided you follow the directions (you didn’t forget to read those did you?). Whether this is your first home theater or surround sound system or one of many upgrades you’ve made along the way I’m sure you will agree that the sound is far superior to the two speaker systems of days not that long ago.


Hopefully the sections above have contributed to your understanding of surround sound systems. Share your new understanding about surround sound system with others. They’ll thank you for it.

Before You Start Learning Electronic Sound Synthesizer

The most commonly used electronic instruments are synthesizers, so-called because they artificially generate sound using techniques such as additive, subtractive, FM and physical modeling synthesis to create sounds. Synthesizers are used for the composition of electronic music and in live performance.


A brief history


The first electronic sound synthesizer, an instrument of awesome dimensions, was developed by the American acoustical engineers Harry Olson and Herbert Belar in 1955 at the Radio Corporation of America laboratories at Princeton, N.J. The information was fed to the synthesizer encoded on a punched paper tape. It was designed for research into the properties. Dr. Robert Moog introduced the first practical commercial modern music synthesizer with his Moog synthesizer. This instrument used a series of tone generators with keys that would adjust the pitch of the tone generators. The first digital synthesizers were academic experiments in sound synthesis using digital computers.


A brief discussion on electronic sound synthesizer


The word synthesis means to produce by combining separate elements. Thus, synthesized sound is sound that a musician builds from component elements. A synthesized sound may resemble a traditional acoustic musical timbre, or it may be completely novel and original. This characteristic is common to all synthesized music. Electronically-generated music has not only generated its own totally separate field of music, but several sub-genres. An electronic music synthesizer is capable of creating sounds that are quite unlike any other instrument known to mankind. Creating and using electronic synthesizers and related sound equipment involves considerable aspects of electrical engineering, physics, and math. Using synthesizers to create music is a field where all of these seemingly disparate branches of knowledge come together to produce what is quite possibly the most elegant fusion of art and science currently known to humanity.


Important features of Electronic sound synthesizer


Some of the most important features which are responsible for creating heavenly music from an electronic sound synthesizer are Oscillators, Filters, Envelope, Amplifier and Equalizer.


Oscillators – An oscillator is simply a circuit that generates a repeating electrical wave, like a sine wave, square wave, or saw tooth wave. The oscillator is sometimes called a VCO. An oscillator on a synthesizer usually allows varying the pitch, volume, and shape of the wave to make the tone sound different.


Filters – A filter is a processing element that does something with a sound, usually eliminating part of a sound. The filter on a synthesizer is sometimes called a VCF. It might eliminate sounds of a certain pitch or volume while allowing other sounds to pass through.


Envelope – The envelope generator is most commonly used to control the amplitude or volume of the sound, by routing it to the control input of the VCA. It is even used to control the timbre of the sound, by routing it to the control input of the VCF.


Amplifier – The amplifier can raise, or lower the height of the waveform, thereby raising or lowering the volume of the sound. To control the volume of a sound in the synthesizer, the signal is passed through an amplifier circuit.


Equalizer – An equalizer is a tool which allows you to selectively amplify or attenuate certain frequency ranges of sound.

Exploring The World Of Non-Formal Sound Therapy

The various options associated with sound therapy come courtesy of the many different kinds of sound that exist in the world. To explore some of the best options, I have listed a few below:


DVDs, CDs, and Tapes for Stress Reduction


One of the most well known categories of sound therapy includes audio products that contain refreshing sounds. This approach may come in the form of music; exploring natural wonder; chanting; words spoken softly; or primitive sounds, such as the echoes of the outside world that a fetus encounters while in the womb. All of these sounds possess the power to send you into a dreamlike state of mind. To get the most out of this process – I suggest lying down or sitting still while listening. However, some people still experience great results when doing various activities at the same time.


When looking for the best in stress reduction CDs and audiocassettes – I recommend seeking out the resources offered through the Center for Neuroacoustic Research (also known as CNR). Since 1980, Jeffrey D. Thompson, the founder of CNR has accumulated extensive research pertaining to sound and healing. As a respected expert throughout many international circles – his studies in the field of neuroacoustic healing has led to the creation of more than 60 CDs and audiotapes centered on acoustic pacing, which is responsible for blending the frequencies of musical sound tracks.


It is his acoustic pacing recordings that can assist the mind and body in discovering a realm of deep relaxation. Stress levels decrease. Overall healing takes place. Pain becomes easier to control. Greater levels of meditation states are reached. Some people are even able to achieve a better night’s sleep. All of this comes as a result of using modulated sound pulses to alter the levels of consciousness in a person, which opens up doors for one to accomplish a higher level of healing.


Music


How many times have you felt more relaxed after listening to your favorite music CD? The sounds of something familiar are great for bringing a sense of calm into your life. I also suggest looking into New Age music.


Vibration Therapy


Comparable to acupressure, a chiropractor or therapist often delivers this dose of therapy, which uses a thick, metal tool (shaped like a rather narrow horseshoe) to create sound and vibration. Wherever it is tapped on the body, an advantageous stream of vibration rejuvenates the surrounding region. Sound vibration is becoming an increasingly popular method of establishing a healthy level within body tissue to promote relaxation.


Tibetan Singing Bowls


Used in meditation circles, singing bowls are a musical instrument associated with the Buddhist culture. You may also see these bowls referred to as a Himalayan bowl or cup gong. When gently hit or rubbed slowly – the metal insides or top surface of the bowl makes a sound that can reduce stress and lessen anxiety. Sometimes, a small mallet of wood is used to produce this harmonious sound. Just keep in mind – this technique is considered quite hard to get the hang of.


Chanting


The constant spoken or sung word or sounds that creates a soothing rhythm is called chanting. Even during ancient times, people found a use for this method while on the battlefield or when participating in religious worship. A few examples of this sound therapy include some Native American traditions, the infamous Gregorian chant, and mantras.


Drumming


Another ancient practice to consider is drumming – often associated with Native American tribes, who created vibrations that easily sent bystanders into a trance-like state of consciousness. However, individuals were still completely aware of their surroundings. Most times, it was the drummer that received the more intense results.


Normally, handmade Native American drums covered with animal skins are used. Luckily, drums come in a multitude of shapes, sizes, and styles – where the palm of your hand or even a soft mallet can achieve the sound you desire.


An increasing popularity regarding drumming circles (with the occasional use of Native American flutes) has been seen about the U.S. The level of energy produced by two or more drummers can create a swelling healing force filled with power. Drumming, especially in a circle can lead to beneficial healing that really reduces stress levels.


Sound Equipment


Don’t worry – this isn’t the kind of equipment a music band relies on – I’m referring to the various types of tools that can create a refreshing sound within the comforts of your own home. This may include a tabletop waterfall or a bubbly fishtank. Some people take pleasure in the soothing sounds of tranquility chimes – consisting of tiny beads that continuously drop to produce a relaxing response.


Overall, no matter what sound therapy approach you select, a regular routine is needed in order to truly eliminate stress. Over time, daily therapy is no longer necessary and you can slowly decrease your schedule to once a week.

Sound Quality Of Digital Video Disk

DVD is a special kind of disc that has a large storage capacity. This disc is mainly used for watching films and music. The sound quality of a DVD is generally very good. But it depends on the quality of the discs. The better quality DVD you opt for, the better the sound quality will be.


The resolution of DVD video is better than the C.D. It’s sound quality is also better than the C.D. The sound quality of a Digital Video Disc is dependent upon the speakers of the Digital Video Disc player. To get a good sound you need to have a good Digital Video Disc player with good speakers. If the sound box is good it will definitely produce a good output.


DVD sound are mainly of two types.


Dolby Digital


Dolby digital sound is one of the newest entries in the arena of DVD sound. This specific sound type is of very good quality. DVDs containing Dolby digital format offer a very realistic sound. This format gives the audience the feeling that they are experiencing the incident directly, not through a Digital Video Disc. There is an option called surround sound. This very sound gives the listener a feeling that the sound is coming from every direction. Actually in a surround sound format, the sound comes from six different sides. These six sides are, near right, front right, center, near left, front left and the sound that comes from sub woofers. Subwoofers give a low bass sound. Dolby digital sound is also very popular for films. Many modern cinema halls use this format.


DTH (Digital Theatre Sound)


Digital theatre sound is a kind of sound that enables a theatre like sound. It is almost like Dolby Digital format, but the sound quality is a bit better. This format has two main types


DTS-S: this system offers four channels. All four of them are matrix encoded. These four channels are, right, left, center, surround. This system is very much like the standard 35mm optical Dolby stereo.


DTS-6: this system has six different channels where the sounds come from. These six channels are, right, left, right surround, left surround and subwoofers. This system is very much like 70mm six track magnetic sound.


DTS format is becoming very popular. This format is also used in cinemas. The price of this format is also quite reasonable.


If you want good sound quality in a DVD, you should have some idea about the discs. Always buy better quality discs. You should opt for well known brand names. The facility of buying brand names is that you will always get quality material since they want to maintain their reputation and status in the market. It is true that they can sometimes be a bit expensive. Nevertheless, if you want to get a good output it shouldn’t hurt to pay a little more

Home Theater Surround Sound: Making Sense Of It All

In case you hadn’t figured it out by now, surround sound is named as it is because the sound literally surrounds the listener. While there have recently been significant leaps and bounds in this technology there was a huge gap in time between the introduction of this technology and the significant improvements we have seen in recent years. This is especially true when the evolution of sound technology is compared to how fast the world of video has evolved over the last three decades.


There are many different formats on the market today. This can be confusing for many consumers though the good news is that most devices that interpret the formats do so automatically. In other words, you won’t need a PhD in terminology in order to enjoy the latest blockbuster hit to come out on DVD with your surround sound system. You will however need a good AV receiver and even better speakers in order to get the maximum enjoyment from your home theater and surround sound system.


If you are simply curious or like to know a little about a lot, then you just might find some of the following explanations for common surround sound formats to be useful. Dolby Digital AC-3 is by far the most commonly seen surround sound format. It is a 5.1 channel format (this means five speakers plus one subwoofer). This is what most DVDs will include and some programs that are found on digital cable or satellite channels will have this type of surround sound as well. You can use Dolby Digital for older mediums that do not include surround sound in their format, as surround isn’t required in order to use the system.


Pro Logic is a system used by Dolby in order to translate or decode the signals from other mediums such as old videocassette tapes or television broadcasts. This is becoming widely known for its ability to take two speaker sounds and turn them into shockingly realistic surround imitations.


DTS is the largest competitor for Dolby when it comes to sound. DTS is this company’s answer to Dolby Digital 5.1 surround sound. This is mostly seen only on DVDs.


DTS-ES is the above-mentioned company’s answer to Dolby’s 6.1 surround system (this is 6 speakers plus 1 subwoofer). Of course DTS is also going to have their own answer to Pro Logic and that answer would be DTS NEO:6, which is said to produce great imitations of surround sound from existing 2 channel mediums very much like Pro Logic.


You may be wondering why we went through all of this information and the primary reason is so that you know there is a difference and you purchase equipment and DVDs that are compatible with one another. Failure to do so could result in a sound that is less than desirable. Most systems will at the very least support both Dolby Digital and DTS, however, you should make sure that you are aware of the format your system requires from the start in order to make the proper decisions when purchasing.


Much like anything in life the proper formats and surround sound system comes down to a matter of choice. The more speakers (such as you would find in the 6.1 or 7.1 surround systems) will present a great quality of sound than fewer, however poor quality speakers can completely ruin the beauty of the sound of your surround sound system. Your speakers should be your single largest investment when it comes to building your ideal surround sound system.


There are many things that go into creating not only the perfect surround sound system for your home but also the perfect surround sound set up. Do not get so caught up in researching these systems online that you neglect to walk into your local stores and actually hear the sound systems you are considering for purchase. There is noting like hearing the quality of the sound to help you make your final selection.

The Importance of Sound Effects

Sound Effects are present in almost every media that you see and hear on a daily basis. From television, movies, and shorts to web sites, and digital music sound effects help tie the pieces together for your brain to understand. Their importance can easily be measured by their absence, when our minds quickly pick out the inconsistency.


Our brains rarely just think on one sense. Most often several of our senses make up the contents of every moment in our perceived time. We see a gun, we watch it fire, but if we don’t hear the gunshot we feel that the experience is somehow broken, fake, or just doesn’t make any sense.


This is why good quality sound effects can come in very handy. Having the exact right sound for your images can be crucial in getting your audience to become completely engulfed in the experience. Sometimes the sounds can be isolated or symbolic, like the ceiling fan in the beginning of “Apocalypse Now”. Much of the other sound effects are removed to focus on the ceiling fan, which is a combination of blades moving quickly past the microphone, and the blades of a helicopter. The symbolism here is that the whirling blades of the fan are reminding Capt. Willard of the call of the jungle.


Sometimes the sounds are a little more collaborative and are mixed together to make a scene sound realistic. Sounds of leather coat, mixed with the jingle of change in the pockets, laid over the sound of a busy airport can create the unconsciously expected realism that your brain is expecting.


But you’ll never get lucky enough to find a prefabricated sound byte that has everything you need laid into it at exactly the right time. That’s why clean, individual sounds are vitally necessary to create the feel that you’ll need. In this way you can mix and match a multitude of various sounds together to create completely new sounds, or a series of orchestrated sounds that complete a collage.


Montage theory (at least one of its aspects) employs juxtaposition of images in order to create new meaning. For example: Show a black and white picture of a sad looking old man, and then show a picture of an empty bowl. Most often our brains put the images together and tell us “this old man is starving”. When in reality the two images have nothing to do with one another. The same thing holds true for sounds, especially when they are blended with images. An obviously imaginary bolt of magic blasts out of a character’s fingertips, we hear some burning lightening magic sound, and suddenly we are immersed in pure fantasy; believing that this person is really able to shoot magic from their fingertips. The icing on the cake, the thing that sells it, is the sound.


The importance of sound in your production is paramount. Cheap sounds pull your audience out of the realism of the experience. This is why high quality sounds should be collected at any price. Good well made sound effects will pay for themselves, though they’ll never make their financial contribution known. It all comes down to the final product. Does it immerse your audience? If not then maybe some tweaking and enhancement of your sound is exactly what’s missing.
