Methods for Measurements of Impulse Noise

This standard describes methods for measurement of impulse noise and presentation of data. Its scope applies to all kinds of impulse noise, whether discrete event sources, such as quarry and mining explosions or sonic booms, or from multiple event sources such as pile drivers, riveting, or machine-gun firing, but not to sounds from other sources which have specific measurement standards based on the general methods for measurement of quasi steady noise. Data which may be reported include characteristics of the time variation of the sound pressure, with or without specific frequency weighting, and sound exposure level.
