Noise Dosimeter Performance.
NTIS: PB 233 486 :39 pages
Eight brands (three samples of each kind) of commercially available audiodosimeters were performance tested. Each unit was placed in an anechoic chamber and subjected to various acoustic signals to measure its a-weighting response and overall integration accuracy. All units met the a-weighting tolerance for type II sound level meters, and six brands were within the Bureau's overall accuracy requirements of +/-2 dba referred to input.
