By the end of this section, you will be able to define intensity, sound intensity, and sound pressure level and to calculate sound intensity levels in decibels (dB).

Pitch is the ear's response to frequency, and here you can get a better understanding of pitch, its measurement and the perception of pitch.

Study the details of sound from characteristics to speed, ultrasound, infrasound, and other aspects of sound waves.

A physics tutorial on designing an auditorium and solving the problem of sound reflection. Illustrated.

A series of pages written by a sound system design group; the pages provide excellent background information about acoustical topics related to the design and analysis of both sound systems and rooms. Contains a lot of good physics in an...

In this video, musician Jake Shimabukuro uses the pitch of musical notes and vibrations in hertz to illustrate the concept of ratios. This clip is from Center for Asian American Media. In the accompanying classroom activity, students...

Here is described a simple process to 'put a voice on a sunbeam' and transmit it over a distance. It is a fascinating example of amplitude modulation of light using sound vibrations. It then describes how the modulated light is detected...
