Sound level meters

Sound level meters

Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. (Sound can propagate through solids as well, but there are additional modes of propagation). Sound that is perceptible by humans has frequencies from about 20 Hz to 20,000 Hz. In air at standard temperature and pressure, the corresponding wavelengths of sound waves range from 17 m to 17 mm. During propagation, waves can be reflected, refracted, or attenuated by the medium.[2]

Octave

An octave is the interval between two points where the frequency at the second point is twice the frequency of the first.

Although the octave is the eighth note of a series in any key - an octave is separated by 5 whole notes and 2 halfnotes.
