Critical Frequencies Measurement:

Coincidence frequency is defined as the Optimum efficiency that is achieved when the plate is vibrated such that the wavelength of flexural waves in the plate is equal to the wavelength of acoustic waves in the air , also called critical frequency.

Use this calculator for the measurement of critical frequencies of a given plane.

Just copy and paste the below code to your webpage where you want to display this calculator.


Formula:

f c = [ sqrt(3)c2/pi*d ] * [ sqrt(ρ/Y) ]


where,

fc = Coincidence Frequency [Hz]
c = Speed of sound in air [ms-1]
d = Thickness of panel [m]
ρ = Density of panel [kgm-3]
Y = Young\'s modulus of panel [Nm-2]
