Acoustics & Vibrations

Wave speed, frequency and wavelength

v=f\lambda

correlates the propagation speed, frequency and spatial period of a single frequency traveling wave.

Acoustics & Vibrations

L_p=20\log_{10}\frac{p_{rms}}{p_0}

uses a logarithmic scale to express the magnitude of the root mean square sound pressure relative to the reference value.

Acoustics & Vibrations

f'=f\frac{c+v_o}{c-v_s}

calculates the change in received frequency when the observer and the sound source move along the line connecting them.

Acoustics & Vibrations

x(t)=A\cos(\omega t+\phi)

describes the periodic displacement of a linear undamped oscillator.
