Lecture 5 Supplement: Derivation of the Speed of Sound in Air
... see a small volume element crossing through the sound wave. The front face experiences a back pressure of P + dP , hence a total force of (P + dP )dydz. The back face experiences a front pressure of P , hence a total force of P dydz, so that the net force on the cube is −dP dydz, in the x-direction. ...

Hearing Sound
... Hearing Sound Sound is energy that travels as longitudinal waves containing regions of high and low pressure. The audible region of the sound spectrum for humans extends from about 16 Hz - 20 kHz. Test your hearing: http://www.noiseaddicts.com/2009/03/can-you-hear-this-hearing-test/ In the 1930s rec ...
