Materiel Design Standard for Noise Levels of Army Materiel Command Equipment

摘要

HEL Standard S-1-63C is the U. S. Army Materiel Command's design standard for noise. It establishes the acoustical noise levels permitted in and around all equipment designed, developed and procured by AMC, and specifies the testing requirements and measurement techniques for determining conformance to the noise limits. Adherence to the provisions of this standard should assure compliance with TB Med 251. The noise levels and test procedures of this standard are intended to cover typical operational conditions and are based on considerations of hazard to hearing, speech intelligibility, aural detection and appropriate state and federal noise limits.
