SOUND FREQUENCY WAVE LENGTH
SOUND FREQUENCY WAVE LENGTH
By: Don McClatchie
All signals both RF and Audio are electromagnetic waves that travel down wires or through the air and they all have a wavelength. The wavelength of any frequency is the distance any frequency travels in the time of one cycle. The distance that the any signal travels through the air in one cycles time is directly related to the frequency of the signal, but also to a lesser degree other factors like the gas composition of the air, air temperature, air pressure, and moisture in the air. Basically, anything that changes the density of the air will affect the time it takes for one cycle to go the distance.
The following sound frequency wavelength chart lists frequencies from 1 Hz that lists the speed of sound in the air at 68 Degrees as 1128.608924 feet per second, and the speed of sound in the air at 95 Degrees with water vapor. You can see how water vapor effects the speed and so the wavelength. The table lists many frequencies from 1 Hz to 100 KHz with many octaves of audio notes also TV and FM radio Pilots are marked in the Notes.
When placing microphones or speakers for recording and listening these distances should be avoided because the wavelength will cause subtractions and additions by interaction with the wavelength of any frequency. Particularly the 1/2 wavelength will cause cancellations of certain frequencies while re-enforcing others. Refection distances should be considered when placing microphones in recording studios and other venues.
A test can be made by using a tone generator output to speakers and monitoring the audio of a single frequency at a time. Slowly sweep through the audio spectrum and measure the microphone level for any level changes that would indicate at what frequencies if any a problem exists.
Every recording studio has its own sound created by the wavelength effect. Studio engineers work very hard at eliminating these audio anomalies but as you can see by the table it is a difficult thing to accomplish.
If you wish to know the wavelength of any other material, simply divide the speed of sound in feet per second through that material by the frequency in cycles and you have your answer.

| When placing speakers and microphones you should avoid placing them at these precise distances apart. | |||||||
