This project aims to control the effects of noise on cetaceans by developing automated classification methods to detect and identify acoustic sources. It also emphasizes the need to establish standards to measure underwater noise and monitor existing noise sources.

Underwater noise – low frequency continuous sound The ambient noise level measured by a statistical representative sets of observation stations in Regional Seas where noise within the 1/3 octave bands 63 and 125 Hz (centre frequency) should not exceed the baseline values of year [2012] or 100 dB (re 1µParms; average noise level in these octave bands over a year).
