What are complex sound waves?

A sound which has more than one (sine-wave) frequency component is a complex sound. A periodic sound is one which repeats itself at regular intervals. A sine wave is a simple periodic sound. Musical instruments or the voice produce complex periodic sounds. They have a spectrum consisting of a series of harmonics.

What are the 3 types of sound waves?

Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves. Keep reading to find out what qualifies them as such. Longitudinal Sound Waves - A longitudinal wave is a wave in which the motion of the medium's particles is parallel to the direction of the energy transport.

Is noise a complex wave?

Sound created in nature are very complex. We can use an oscillator to create less complex waves but even relatively simple waves, such as a square wave, are many times more complex than a sine wave.
