Mar 2, 2015 · The volume of sound is measured in decibel (dB), which are a measure of air pressure. Sound pressure level (SPL) or sound level Lp is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels (dB) above a standard reference level.
- The sound intensity is $I = \xi^2 \omega^2 c \rho$ where $\xi$ is the particle displacement, $\omega$ the frequency, $c$ the speed of sound and $\...

The air presure required in your fork will vary depending on the model of fork, and the style of your bike. For DebonAir, SoloAir, and Dual Postion Air, you will determine require pressure based on the percent sag, the amount of full travel that the suspension compresses when the ride is on the bicycle in a normal riding position.
The compressions are regions of high air pressure while the rarefactions are regions of low air pressure. The diagram below depicts a sound wave created by a tuning fork and propagated through the air in an open tube.
