# Frecuencias de medición críticos: Español English

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.

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.

#### 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 = Youngs modulus of panel [Nm-2]
