Definition

vector (ISO 80000-2: Mathematics) quantity given by:

a = \frac{\partial u}{\partial t}

where $u$ is sound particle velocity (sound particle velocity) and $t$ is time

grandeur vectorielle donnée par:

a = \frac{\partial u}{\partial t}

où $u$ est la vitesse acoustique d'une particule (sound particle velocity) et $t$ est le temps

Units

Notes

The definition is limited to small-amplitude acoustic disturbances such that the magnitude of the sound particle velocity is small relative to the phase speed (ISO 80000-3: Space and time) of sound.

La définition se limite aux perturbations acoustiques de faible amplitude telles que la norme de la vitesse acoustique d'une particule soit petite par rapport à la vitesse de phase (ISO 80000-3: Space and time) du son.
