The Demonstration: Someone speaks into a microphone that is connected to an oscilloscope and you can see the patterns creates by their voice. Quick Physics: Sound is a wave that caused by vibrations in the air. A pure musical sound, such as a whistle, will produce a sine wave like the one shown above.Someone just talking with produce an irregular wave because it is a combination of sounds and the sounds waves add together to get the composite shown on the oscilloscope.The Details: You can see sound waves when a microphone is connected to an oscilloscope.A microphone changes the sound waves into an electrical signal. The oscilloscope then shows what these electrical waves look like.For a pure sound of only one frequency, like a tuning fork or whistling, the wave looks smooth and regular (as in the picture below). pure musical sound, such as a whistle, will produce a sine wave like the one shown above. Someone just talking with produce an irregular wave because it is a combination of sounds and the sounds waves add together to get the composite shown on the oscilloscope.
