The amplitude and frequency of a sound wave can be examined using a microphone and oscilloscope. By measuring the speed of sound we can apply the wave equation to determine its wavelength.

How sound waves work. Sound waves are a type of energy that’s released when an object vibrates. Those acoustic waves travel from their source through air or another medium, and when they come ...

A sound at one frequency may seem louder than one of equal pressure amplitude at a different frequency. The curves shown in Figures 2.0 indicate how the perceived loudness is a function of both the ...
