Good Practice Guide for Underwater Noise Measurement

The Good Practice Guide for Underwater Noise Measurement presents best practice for in-situ measurement of underwater sound, data processing and the reporting of the measurements using appropriate metrics.

Measured noise levels are sometimes difficult to compare because of the use of different measurement methodologies or acoustic metrics, and results can take on different meanings depending on the application. This leads to a risk of misunderstandings between scientists from different disciplines.

Acoustical oceanography, sonar, geophysical exploration, underwater communications and offshore engineering all require acoustic measurements. More recently, there has been an increased need to make in-situ measurements of underwater noise for the assessment of risk to marine life, such as whales and dolphins.

This Guide addresses the need for a common approach and the desire to promote best practice. It is designed for those making in-situ measurements of underwater sound, for example consultants, offshore developers, oil and gas companies, and developers of marine renewable energy, as well as regulators wishing to base their requirements on a firm scientific foundation.
