Sound system:Device that harnesses acoustic startle response due to be tested on Scottish farms

摘要

The deployment of conventional high-power acoustic deterrent devices (ADDs) to keep marine mammals away from fish farms work on the principle of inducing pain in the auditory system of target animals.The ADDs, sometimes also labelled acoustic harassment devices (AHDs), emit sound at very high source levels and duty cycles. But the long-term success of these devices is generally limited and habituation -a decrease in responsiveness to the signal - isoften a significant problem in contexts where food motivation is involved
