Audiometry Screening and Interpretation | AAFP Testing should begin at 1,000 Hz, because this frequency is easily heard by most patients and has the greatest test-retest reliability. In many media, such as air, the speed of sound is approximately independent of frequency, so the wavelength of the sound waves (distance between repetitions) is approximately inversely proportional to frequency. Sound absorbing materials like acoustic panels and soundproof foam are often the best tools for this. It is measured in terms of frequency and amplitude.

It occurs very gradually and you may not even notice it, until it's advanced. The more dense a material, the more difficult it is for sound waves to penetrate. Sound frequencies above 20kHz are called ultrasonic. Just like the super low frequency infrasound, ultrasound can affect us even though we cant hear it. See related patient information handout on preventing noise-induced hearing loss, written by the author of this article. The difference in pitch stems from the oscillation, or the regular back and forth of the sound waves that emanate from those two sources.
