The sea is no longer a world of silence, many noises are generated by maritime traffic, oil drilling, etc. Oil and gas seismic explorations and offshore wind farms also generate waves that have negative effect on cetaceans. This noise pollution affects cetaceans that have very sensitive hearing because they use sound for communication and echolocation to move and hunt.

Consequences of this pollution are diverse and sometimes fatal: disruption of communication between cetaceans, behavioural changes, abandonment of feeding areas, disorientation leading to beaching, internal bleeding, stress that may affect reproduction, etc.

The level of noise pollution is increasing and it is imperative to further investigate its effects on cetaceans in order to take necessary measures.
