Abstract
A three part test procedure to determine the Random Incidence Relative Response Levels of an industrial sound level meter (ISLM) is presented. Test requirements are derived from NIOSH requirements for certifying ISLM sets and from American National Standards Institute specifications. The three procedural parts comprise a method to monitor the ISLM reading without having to read the ISLM scale, the determination of the low frequency response of the ISLM using a 31.5 to 250 Hertz low frequency chamber, and the determination of the Random Incidence Response Levels of the ISLM using an anechoic chamber. The latter procedural part includes a determination of the effect of a windscreen on the ISLM.
