Abstract
Analyses with a waveform analyser were made of the time and frequency domain of impulse noise from both military guns, e.g. rifles, cannons, bazookas and mortars, and explosions. For heavy weapons the most prominent energy content was found to be in the frequency range below 100 Hz. The frequency peak was generally less than 50 Hz. The significance for the A-weighting of noise impulses from weapons is discussed, as well as the different impulse parameters, e.g. peak value, impulse energy and A-duration.Keywords
