Impulsive Noise

A noise level that fluctuates over a range greater than 10 dB during observation is classified as impulsive.

Impulsive sounds, such as gun shots, hammer blows, explosions of fireworks or other blasts, are sounds that significantly exceed the background sound pressure level for a very short duration.

C-weighted levels have been found useful for ratings of gun shots (ISO 1987).
