The acoustical output of marine-seismic airguns is determined from recordings of the sound pressure made on hydrophones suspended below a floating barge from which the airguns are also deployed. The signals from multiple types of airguns are considered and each type is operated over a range of deployment depths and chamber pressures. The...

This report is the result of Phase 2 of a two-phase project for the standardization of measurement, processing and reporting procedures for offshore oil and gas exploration and production-related sound sources. This project was carried out for the E&P Sound and Marine Life Joint Industry Programme of the International Association of Oil & Gas...

Environmental risk assessment for impact pile driving requires characterization of the radiated sound field. Damped cylindrical spreading (DCS) describes propagation of the acoustic Mach cone generated by striking a pile and predicts sound exposure level (LE) versus range. For known water depth and sediment properties, DCS permits extrapolation...

Regulations for underwater anthropogenic noise are typically formulated in terms of peak sound pressure, root-mean-square sound pressure, and (weighted or unweighted) sound exposure. Sound effect studies on humans and other terrestrial mammals suggest that in addition to these metrics, the impulsiveness of sound (often quantified by its kurtosis...

As countries explore renewable energy opportunities, offshore wind farms are being developed along coastlines. To construct these wind farms, piles are driven into the seafloor as foundational structures for the turbines. Pile driving involves risk of noise pollution that can affect marine fauna. To mitigate these risks, risk assessments and...
