To reduce the impact of high power underwater sound sources, Acoustic Risk Mitigation Policies have been drawn up and are currently under implementation. Basically, ARMP are aimed at preserving particularly populated areas and critical habitats, and at reducing or stopping emissions if animals are within a defined distance. Among tested approaches, passive acoustics has shown to be an efficient tool to (a) expand knowledge about marine mammal distribution in space and time (i.e. with surveys), (b) characterise biological and artificial sources, (c) evaluate effects of sound exposure on animals' behaviour, and (d) monitor, detect, locate and track vocalising animals within, or approaching, a sound exposure area. Instruments and protocols for the passive acoustic detection of marine mammals developed at the University of Pavia are described.

Abstract
To reduce the impact of high power underwater sound sources, Acoustic Risk Mitigation Policies have been drawn up and are currently under implementation. Basically, ARMP are aimed at preserving particularly populated areas and critical habitats, and at reducing or stopping emissions if animals are within a defined distance. Among tested approaches, passive acoustics has shown to be an efficient tool to (a) expand knowledge about marine mammal distribution in space and time (i.e. with surveys), (b) characterise biological and artificial sources, (c) evaluate effects of sound exposure on animals' behaviour, and (d) monitor, detect, locate and track vocalising animals within, or approaching, a sound exposure area. Instruments and protocols for the passive acoustic detection of marine mammals developed at the University of Pavia are described.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
