Description:
In modern times, the idea that sound consists of waves is a generally accepted truth. In ancient times, however, theories about sound ranged from the idea of streams of atoms, proposed by Gassendi, to ray theories, in which sound travels linearly, proposed by Reynolds and Rayleigh.1 However, evidence for the wave theory, such as diffusion of sound around corners and the detection of distinct frequencies of sound by Pythagoras
