We Can Distinguish Three Aspects of Any Sound

Multiple Choice

We can distinguish three aspects of any sound. First, there must be a source for a sound; and as with any source, the source of a sound wave is a vibrating object. Second, the energy is transferred from the source in the form of longitudinal sound waves. And third, the sound is detected by an ear or an instrument. Douglas C.
