Hydrophones are generally calibrated in acoustic fields with temporally localized (short pulse) or long duration (tone burst) signals. Free-field conditions are achieved by time gating any reflections from the hydrophone body, mounting structures and

Low frequency Acoustics, Underwater Acoustics and Vibration (AUV) phenomena in water are used to detect major natural events such as earthquakes, tsunamis and volcanic activity, and are also used by the International Monitoring System (IMS) of the Co

Inter-laboratory testing is often undertaken between different National Metrology Institutes (NMIs) by comparison exercises with laboratories calibrating the same hydrophones. The expectation is that results will be within a small tolerance with each

Absolute measurement of sound in the ocean is becoming increasingly ubiquitous, a common driver being the requirement for monitoring marine noise in support of regulation for the protection of the marine environment. In these measurements, the perfor

A description is given of the results of a Key Comparison of primary free-field standards for underwater acoustics at frequencies from 1 to 500kHz. This is the first such Key Comparison exercise in the field of underwater acoustic calibration and mea

Underwater radiated noise is often an unintended byproduct of offshore activities, and the increasing levels of man-made sounds in the ocean (whether deliberately generated or not) have led to concern over marine noise pollution and its effect on mar
