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 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).

Examples of Impulsive noise in a sentence

• Impulsive noise has high peaks of short duration and a sequence of such peaks.Intermittent noise is characterised by the level suddenly dropping to the background noise levels several times during a measurement, with a noticeable change in noise level of at least 5 dB.

• With the implementation and deepening of the "west-east power transmission" strategy, China has gradually formed a number of large receiving terminal systems such as Beijing, Shanghai and Guangzhou.

• Impulsive noise has high peaks of short duration or a sequence of such peaks.Intermittent noise is characterised by the level suddenly dropping to the background noise levels several times during a measurement, with a noticeable change in noise level of at least 5 dB.

• Impulsive noise may cause negative effects of different magnitude, according to the characteristics of the noise emissions.

• Impulsive noise survey on power line communication networks up to 125 kHz for smart metering infrastructure in systems with solar inverters in Turkey.

More Definitions of Impulsive noise

Impulsive noise means all non steady noise usually characterised as impact or impulse 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 short bursts of a acoustical energy, measured at a receiving property line, characterized by a rapid rise to a maximum pressure followed by a somewhat slower decay, having a duration not greater than one second and a field crest factor of 10 dBA or more. Impulsive noise may include, for example, noise from weapons fire, pile drivers, or punch presses.

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 variation in sound level that involve maxima at intervals of greater than one per second;

Impulsive noise means a noise generating excursions of usually less than one second.

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.
