Purpose: Show the wave shape of various sounds.
Description: This setup can be used to look at the wave shape of the speaking voice, singing, whistling, playing musical instruments, musical synthesizers, oscillators with speakers, etc. The oscilloscope trace shown is that of a male voice singing the vowel "ee" with a frequency of about 160 Hz. The photographs from the oscilloscope above compare the sounds of a square wave with a clarinet (top), a sawtooth wave with a crumhorn (center), and a triangular wave with a recorder (bottom).
