scope:

This standard prescribes instrumentation and procedures required for the measurement and analysis of, and maximum acceptable sound level criteria for, airborne sound generated by shipboard equipment.

Airborne sound measurements are conducted to demonstrate that equipment levels are within the limits specified herein.

This standard supplements specifications and similar documents applicable to all shipboard equipment.

Implementation guidance is provided in section 6.

Two basic types of measurement are required by this standard: Weighted sound pressure (average for all measurements and peak for selected measurement) levels; and octave band sound pressure levels.

Airborne sound acceptance criteria are specified in 5.1.

Equipment is acceptable when none of the airborne levels measured at the designated locations exceed the applicable acceptance criteria.

intended Use:
