Prediction of marine mammal auditory-impact risk from Acoustic Deterrent Devices used in Scottish aquaculture

Acoustic Deterrent Devices (ADDs) are used worldwide to deter pinnipeds from predating fish-aquaculture facilities. Desk-based noise-propagation modelling of six commercial ADD models, and a ‘fictional’ ADD was performed, the latter involving alternating source level, frequency, duty cycle, noise-ex...
