How do dolphins react to noise?

Dolphins use sound for echolocation, communication and social interaction. Therefore, noise and other disturbances in their environment can have many negative impacts on dolphins, such as:

- Impaired echolocation: Loud noise can mask the sounds that dolphins use for echolocation, making it difficult for them to find food and avoid predators.

- Disruption of communication: Noise can interfere with the communication between dolphins, making it difficult for them to coordinate their movements and group activities.

- Stress and physiological effects: Chronic exposure to loud noise can cause stress and other negative physiological effects in dolphins, such as reduced immune function, increased heart rate and changes in behavior.

- Hearing damage: Long-term exposure to high levels of noise can damage the hearing of dolphins, leading to permanent hearing loss.

- Habitat displacement: Dolphins may avoid noisy areas, leading to changes in their habitat and distribution patterns.
