23、ted underwater sound during percussive pile driving.Sound is often an unintended by-product of man-made activities, and the increasing number of sound-producing human activities in oceans, seas, lakes, rivers and harbours have led to concern over noise pollution from unwanted sound and its potential
24、 effect on aquatic life. In some countries, there is already incipient regulation with regard to the impact of the radiated underwater sound, requiring acoustic monitoring for environmental impact assessment during construction projects.Percussive pile driving can be a significant source of low-freq
