Détails
This standard describes the measurement systems, procedures, and methodologies used for the
beam aspect measurement of underwater sound pressure levels from ships for a given operating
condition. The resulting quantities are reported as nominal source level values in one-third octave
bands. It does not require the use of a specific ocean location, but the requirements for an ocean test
site are provided. The underwater sound pressure level measurements are performed in the far-field
and then corrected to a reference distance of 1 m. This standard is applicable to any and all surface
vessels either manned or unmanned. This standard is not applicable to submerged vessels or to
aircraft. Measurement systems are described for measurement of underwater sound pressure levels
and also the distance or range between the underwater transducers and the subject vessel.
Processing and reporting of the data are described, and informational guidance is provided. This
standard does not specify or provide guidance on underwater noise criteria.
