Impulse sound definition
Impulse sound means either a single pressure peak or a single burst (multiple pressure peaks) for a duration of less than one second as measured on a peak unweighted sound pressure measuring instrument or "C" weighted, slow response instrument and specified by dB and dBC respectively.
Impulse sound means sound of short duration, generally less than one second, especially of high intensity, abrupt onset and rapid decay, and often rapidly changing spectral composition.
Impulse sound means sound of short duration, much less than one second, with an abrupt onset and rapid decay, separated in time by at least one second.
More Definitions of Impulse sound
Impulse sound. (or noise) means sound consisting of a single pressure peak, or a sequence of such peaks, or a single burst with multiple pressure peaks whose amplitude decays with time, or a sequence of such bursts.
Impulse sound means either a single pressure peak or a single burst of multiple pressure peaks which occur for a duration of less than one second as measured on a peak unweighted sound level meter.
Impulse sound means a short burst of acoustical energy such as that produced by weapons fire, a punch press, or a drop hammer. A pressure time history of a single impulse includes a rapid rise to a maximum peak pressure followed by a somewhat slower decay, both occurring within 1 second.
