Does sound have a dual nature?

Mechanical waves, such as sound, are different of electromagnetic waves because they need a medium to propagate. So, as Alexander mentioned, propagation of mechanical waves are basically vibration in a material stuff. However, this motion CAN be quantized, using a quasi-particle called phonon. read more

Important parts of our experience with sound involve diffraction. The fact that you can hear sounds around corners and around barriers involves both diffraction and reflection of sound. read more

The dual nature of light refers to the fact that light can act as both a wave and a particle. Albert Einstein's photoelectric effect experiment proves that light can behave as a particle while Thomas Young's double-slit experiment shows that it also behaves as a wave. read more

If you consider sound phenomenon you have to consider it as a wave. But if you consider deep within the medium it's own matter waves, you have to accept both the wave and the particle nature of it because if something is making a matter wave, it can also be thought of as a particle. read more
