  • Anthropogenic underwater sound such as ship radiated noise, pile driving noise. underwater explosive blast and so on, affects marine animals. This study describes the effects of underwater noise on fishes. The characteristics of noise, fish hearing and response, and sound propagation loss are analysed based on existing results and measured data in marine construction site. Finally, the safety zone range of fish on man made underwater noise is derived.

  • Underwater impulsive sound such as underwater blasting noise, piling noise and stone breaking hammer affects marine animal hearing response and organs. This study describes the characteristics of various impulsive noise from waterfront construction site and their effect on fish. Time constant, peak pressure, energy and SEL(sound exposure level) of four different underwater impulsive sounds are quantified. Auditory and non-auditory tissue damage ranges are derived by comparing their quantities to the exposure criteria for fish. Damage ranges of auditory tissue and non-auditory tissue of underwater boring blast of 150 kg of charge, are about 100 m and 300 m, respectively. Other three impulsive sounds also gives damage effects but less than that of underwater boring blast.
