Underwater acoustics. Measurement of radiated underwater sound from percussive pile driving Ingestion-build-63436 Manufacturers of single-mode optical fibres1 Scope This document describes the methodologies, procedures, and measurement systems to be used for the measurement of the radiated underwater acoustic sound generated during pile driving using percussive blows with a hammer. A major motivation for undertaking measurements of the sound radiated during percussive pile driving is as part of an assessment of impact on aquatic fauna required by regulatory frameworks. This document describes a generic
