ANSI ASA S1.4 Part 1 Electroacoustics - Sound level meters - Part 1 Specifications (IEC 616721)

RegSenseEnforcement and Audits - OSHAEnforcement and Audits - OSHAAcoustical Society of America (ASA)Safety & HealthHearing Conservation and NoiseGeneral Industry SafetyIndustrial HygieneConsensus StandardsIndustry Consensus StandardEnglishFocus AreaUSA

This standard covers three basic types of sound level meters: Types 1, 2, and 3 with Type 3 having the most stringent performance requirements. Among other things, the standard requires that sound level meters be designed to minimize vibration effects from airborne noise, and that modifications to sound level meters be demonstrated to meet the standard’s requirements and specifications. OSHA references ANSI S1.4 in its 1910.95 standard on occupational noise exposure.
