A survey of ambient noise levels in a variety of environments, where fish are found or raised, has been conducted. Included in the survey were regions in the open water of the Chesapeake Bay, fish pens used by aqua farms in several states, and closed cycle tanks used for aqua-culture research and for public exhibitions. One-third octave-band and narrow-band measurements of the ambient noise levels will be presented. Sound recordings will also be played to demonstrate other characteristics of the noise at the different sites. [Work partially supported by Dual Use Technology Program, NAVSEA.]
