particle velocity

2.63  particle velocity. In a sound field, the vector velocity caused by a sound wave of a given infinitesimal part of the medium, with reference to the medium as a whole. Unit, meter per second (m/s); symbols, u, v....

sound exposure

2.62  sound exposure. Time integral of the square of an instantaneous frequency-weighted sound pressure signal. Unit, pascal-squared second; symbol, E, abbreviation, SE. Annotation 1          Where the frequency...

effective sound pressure

2.61  effective sound pressure. At a point, root-mean-square of a sound pressure signal at the time of observation. Unit, pascal...

peak sound pressure
