About This Item

New methods are available to assist in evaluating the risk of impulse noise-induced hearing loss from inflatable devices, for example, airbags and seat belt pretensioners. This document presents some background on impulse noise measurement techniques and assessment criteria. Related information relative to test details, for example, preamplifier specifications and filtering methods and criteria, will be discussed in a future recommended practice. The sample rate advocated for noise measurements in 2003 was "50 kHz" however when J247 was completed we decided "48 kHz" was more appropriate. To maintain consistency between these two documents I went ahead and made that same change, so now J2531 advocates "48 kHz". The reason for advocating any sampling rate at all was to maintain consistency between test labs.
