The potential for creating underwater noise disturbance is one environmental impact that must be
accounted for by wave energy developers to meet the needs of regulatory agencies. This review
study has been conducted to provide a concise knowledge base of the expected underwater noise
conditions in the near shore environment in regions of the Oregon coast where wave energy
projects could be developed and to present an overview of noise measurement methodologies
that would be suitable for the effective regulatory assessment of potential acoustic impacts. This
report is intended as a reference to be used by wave energy developers in the specification and
selection of approaches to underwater noise measurement that would be acceptable to regulatory
bodies, consistent with the state of the industry and cost effective to implement.
In an attempt to address some of the uncertainties surrounding these types of environmental
noise assessment studies, this report provides information on the expected existing ambient noise
conditions, the sound propagation characteristics of the environment, and the expected sources of
noise associated with various types of wave energy devices. Guidelines detailing specific noise
measurement studies are provided, along with a listing of several commercially available devices
that are suitable for performing these measurements.
Oregon Wave Energy Trust and the OSU Libraries cooperate to provide long-term access to OWET reports. OSU's ScholarsArchive is the digital repository for continual access to the report. The OWET website, http://www.oregonwave.org, provides immediate access to OWET funded reports.
