Define the pitch of a sound as being a function of the frequency of the sound wave. Indicate how the thickness of the vibrating body will change the frequency of the sound and thereby the pitch. Discuss the infrasonic and ultrasonic parameters of sound waves as received by various species.
Discuss the speed of sound changing with the media and the temperature of the media. Define intensity and soundness of sound, discuss the objective and subjective involvement of sound. Introduce decibels as the intrinsic objective measurement.
