Definition: time integral of squared, instantaneous A-frequency-weighted sound pressure over a stated time interval or event, such as an aircraft flyover. The frequency weighting may be other than A, if so specified

NOTE 1 – Duration of integration is implicitly included in the integral, and need not be reported explicitly.

NOTE 2 – The unit of sound exposure is the pascal-squared second (Pa2s), if time is in seconds ; the pascal-squared kilosecond (Pa2ks), if time is in kiloseconds ; the pascal-squared hour (Pa2h), if time is in hours.
