Abstract
This report describes the development and validation of a new impulsive noise instrument to facilitate the measurement and characterization of impulsive noise and its effects on hearing of exposed workers. The long term objective of developing an impulsive noise instrument is to improve and expand the collection of empirical data on impulsive noise exposures which in turn should facilitate the development of a universally agreed-upon damage risk criterion. A damage risk criterion for impulsive noise will allow NIOSH to update its criteria document on occupational noise exposure and provide recommendations for safe exposures. The report provides an overview of the development, system description, operation, and validation of the impulsive noise measurement system. The meter was evaluated in the NIOSH impulsive noise laboratory using a shock-tube that produces impulses from 130-170 decibels (dB) and in the field at several firing ranges measuring impulse noise levels generated by small firearms from 150-185 dB. The meter outperformed current measurement systems with respect to real-time measurements, ease of use and setup, and providing on the spot assessment of the risk to workers.
