Abstract:
Driven by the concern that impulsive noise produced by offshore pile driving may lead to mortality of fish larvae, a device was developed for testing the sensitivity of small fish and fish larvae to sound exposure. The device consists of a rigid-walled cylindrical chamber (110-mm diameter, 160-mm height), driven by an electrodynamical sound projector. Samples of up to 100 larvae can be exposed simultaneously to a homogeneously distributed sound pressure and particle velocity field, at a controllable static pressure up to 3 bars. Two configurations are available with either a dominant sound pressure or a dominant particle velocity exposure. Recorded piling noise can be reproduced in a controlled way, in the frequency range between 50 Hz and 1 kHz, at zero to peak pressure up to 40 kPa and single pulse sound exposure levels up to 187 dB re 1 μPa2 s, or peak particle velocity up to 2.2 cm/s and integrated square particle velocity level 124 dB re 1 (nm/s)2 s. Tests are carried out in which sole (Solea solea) larvae at different stages of development were exposed to various levels and durations of piling noise.
