Fast sound amplitude

The sound velocity amplitude is the maximum value of the sound velocity . Since this is an alternating quantity, it is usually specified as an effective value or as a peak value. If the particle movement takes place in a transmission medium (mostly air), the following relationship applies between the amplitude of the sound velocity and the deflection amplitude (amplitude or sound amplitude).

${\displaystyle v={2\cdot \pi \cdot f\cdot \xi }={\omega \cdot \xi }\,}$

The unit of sound velocity is m / s.

Where:

Fast sound amplitude ${\displaystyle v\,}$

Frequency in Hz ${\displaystyle f\,}$

Deflection of air particles ( sound deflection ) ${\displaystyle \xi \,}$

${\displaystyle \xi \,}$ is the Greek letter xi, pronounced ksi

Angular frequency = 2 · · ${\displaystyle \omega \,}$ ${\displaystyle \pi \,}$ ${\displaystyle f\,}$
