Impulsive noise definition
Impulsive noise means sound characterised by brief excursions of sound pressure (acoustic impulses) that significantly exceed the background sound pressure. The duration of a single impulsive sound is usually less than one second.
Impulsive noise means noise characterized by brief bursts (usually less than one (1) second in duration) of sound pressure which exceed the sound pressure of the ambient environment.
Impulsive noise means all non steady noise usually characterised as impact or impulse noise;
Examples of Impulsive noise in a sentence
Impulsive noise may cause negative effects of different magnitude, according to the characteristics of the noise emissions.
Recalling also the work carried out for the implementation of the Marine Strategy Framework Directive of the European Union, noise can be classified in two categories: - Impulsive noise, defined as a sound emitted by a point source comprising one or more pulses of short duration and with long gaps between these pulses1 - Continuous noise, commonly defined as background noise without distinguishable sources2.
More Definitions of Impulsive noise
Impulsive noise means a noise of short duration usually less than one second and of high intensity, with an abrupt onset and rapid decay.
Impulsive noise. ” means either a single sound pressure peak (with either a rise time less than 200 milliseconds or total duration less than 200 milliseconds) or multiple sound pressure peaks (with either rise times less than 200 milliseconds or total duration less than 200 milliseconds) spaced at least by 200 millisecond pauses.” Minn. R. 7030.0020, subp. 6 (2017).
Impulsive noise means a noise generating excursions of usually less than one second.
Impulsive noise means a noise characterized by brief excursions of sound pressures whose peak levels are very much greater than the ambient noise level, such as might be produced by the impact of a pile driver, punch press or a drop hammer, typically with one second or less duration.
Impulsive noise means a single noise event or a series of single noise events, which causes a high peak noise level of short duration (one second or less), measured at a specific location. Examples include, but are not limited to, a gun shot, an explosion or a noise generated by construction equipment.
Impulsive noise means a noise usually less than one second in duration, characterized by brief excursions of sound pressure (acoustic impulses) which significantly exceed the ambient environmental sound pressure.
Impulsive noise means a noise containing excursions usually less than one second, or sound pressure level 20 dB(A) or more over the ambient sound pressure level using the fast meter characteristic.
