scope:

This standard establishes acoustical noise limits and prescribes testing requirements and measurement techniques for determining conformance to the noise limits specified herein.

This standard applies to the acquisition and product improvement of all designed, or purchased (non-developmental items) ground systems, subsystems, equipment, and facilities that emit acoustic noise. This standard is intended to address noise levels emitted during the full range of typical operational conditions.

This standard provides criteria for designing materiel having noise levels that:

a. Minimize noise induced hearing loss.

b. Achieve acceptable speech communication in a noisy environment.

c. minimize aural detection by an enemy.

d. minimize community annoyance.

intended Use:
