Zusammenfassung englisch
Functional marine mammal acoustic communication evolved under natural ambient noise levels, which makes communication vulnerable to anthropogenic noise sources. In this report, we consider the potential long-range effects ofairgunnoise on marine mammal communication range. During the propagation process, airgun impulses are reflected multiple times from the sea surface, refracted in sound channels and reverberated, leading to signal stretching that may result in a continuous received sound.
