Abstract: The characteristics of underwater noise covering ambient, biological and those noises generated by economic activities in waters of Terengganu are studied by using passive acoustics technique. Noise data were collected at several locations in Kuala Terengganu coastal waters including Bidong Island and Merang Jetty. Additional data were also collected from freshwater environment in Kuala Terengganu River and Kenyir Lake for the purpose of comparison to the marine environment. The underwater recording system consists of a hydrophone, amplifier, laptop and processing software. Sound processing and analysis were carried out using Sound Forge 7.0, Raven Pro Ver. 1.3, Matlab R2008a and Audacity software to generate noise spectrum and spectrograms.
