Bessel's functions are often used in acoustics for describing circular membranes behaviour (exploited by most of the musical instruments). They are the solutions of the wave equations using polar coordinates. Set the properties of the membrane Bessel's functions describe the vibrational modes of the membrane.

Itâs not an equation or anything, but a way to describe a property of something. Hereâs the easy definition, and a way to remember it.
