|a Temporal and Spatial Variations in Sound Produced by a Wave Energy Converter: Sound produced by wave energy converters may affect marine mammal behavior and information is limited, so this study was done to ensure sound levels do not exceed agreed thresholds. Acoustic measurements of the WEC included the type of sound produced, the variation of sound vary in space, and in time. With the NWEI Azura, the primary mechanism for sound production was the hydraulic generator, with secondary production from wave interaction, and primarily produced sound at frequencies less than 3 kHz. From further research efforts at the Navy's Wave Energy Test Site (WETS) in Hawaii, acoustic measurements indicated that the sound from individualWEC devices is of limited environmental consequence, with the intensity and frequencies of sound well below those produced by recreational watercraft and ocean-going container vessels at a range of several hundred meters. As expected for this scale of WEC, no operating states have been identified under which the acoustic emissions exceed regulatory thresholds.
