Tolerance of harbour porpoise hearing to single airgun impulses

• Harbour porpoises are negatively affected by intense sound at lower levels than marine mammal species tested so far.
• A noise exposure criterion combining peak pressure (200 dB re 1µPa) and energy flux density (164 dB re 1µPa^2s) should be applied for anthropogenic activities.
• The cumulative effect of multiple exposures and continuous signals on harbour porpoises needs to be tested.
• Simple and effective sound mitigation measures need to be developed and ap-plied wherever possible.
• Seals (harbour seal + grey seal) need to be considered in this context too.
