In 1995 a comprehensive book on the relation between marine mammals and noise had been published, and it did not even mention strandings. In 2013, research showed beaked whales were highly sensitive to mid-frequency active sonar. Blue whales have also been shown to flee from the source of mid-frequency sonar, while naval use of mid- and high- frequency side-scan sonar was deemed 'the most probable cause' of a mass stranding of around 50 short-beaked common dolphin ("Delphinus delphis") on 9 June 2008 in Falmouth Bay, Cornwall, UK.
