Recent studies suggest that noise pollution can harm whales directly by damaging their hearing, and in extreme cases, causing internal bleeding and death. More commonly, it appears that excessive or prolonged noise can cause behavioral changes that interfere with the health and survival of the animals.

Noise pollution is defined as annoying or harmful levels of noise. The cumulative effects of noise pollution can affect our physical and mental health. Reducing noise pollution can be achieved through regulation, improved building methods, better product design, noise barriers and better planning.
How can pollution affect whales?
Some affected whale populations are set to die out within a generation. The PCBs that whales, dolphins and porpoises absorb from their food end up being stored mainly in their fatty tissue (blubber). The levels of PCBs in an animal’s blubber will build up over time as it consumes more and more contaminated fish.
How does ocean noise affect whales?
Vessel-generated underwater noise can affect humpback whales, harbor seals, and other marine mammals by decreasing the distance over which they can communicate and detect predators and prey.
Why is noise pollution bad for the ocean?
Noise can travel long distances underwater, blanketing large areas, and potentially preventing marine animals from hearing their prey or predators, finding their way, or connecting with mates, group members, or their young. Decreased species diversity in whales and dolphins was related to an increase in seismic noise.
How does noise pollution affect sea animals?
These rising noise levels can negatively impact ocean animals and ecosystems. Higher noise levels can reduce the ability of animals to communicate with potential mates, other group members, their offspring, or feeding partners.
Does underwater noise affect whales?
Vessel-generated underwater noise can affect humpback whales, harbor seals, and other marine mammals by decreasing the distance over which they can communicate and detect predators and prey.
How does boat noise affect whales?
“As ship noise increases, it’s literally – not metaphorically –it’s literally shrinking the whales’ world,” he said. ” It’s shrinking the range over which their calls are audible, which means it’s shrinking the range at which the whales can stay in contact, coordinate their movements, share their prey.
How are whales adapting to noise pollution?
In an increasingly noisy ocean, how are whales adapting? Parks and her colleagues conducted acoustic research on two closely-related species, North Atlantic and South Atlantic right whales, and found that they had shifted communications to a higher frequency.
How does water pollution affect whales?
Some affected whale populations are set to die out within a generation. The PCBs that whales, dolphins and porpoises absorb from their food end up being stored mainly in their fatty tissue (blubber). The levels of PCBs in an animal’s blubber will build up over time as it consumes more and more contaminated fish.
How does noise pollution affect humpback whales?
Recent studies suggest that noise pollution can harm whales directly by damaging their hearing, and in extreme cases, causing internal bleeding and death. More commonly, it appears that excessive or prolonged noise can cause behavioral changes that interfere with the health and survival of the animals.
How does ocean noise affect blue whales?
High levels of noise from shipping, oil and gas exploration, naval sonar training and construction are drowning out the ocean’s natural sounds. This diminishes the ability for whales, dolphins and other marine life to communicate, feed, breed and survive. In severe cases, it can lead to injury or even death.
How does noise pollution affect whales and dolphins?
The most striking consequence of ocean noise pollution is the stranding of whales and dolphins. Strandings have been observed to be particularly frequent after naval sonar manoeuvres. Extreme sound events like these inflict vascular damage on the brain, lungs and other organs.
How does underwater noise pollution impact whales?
And the impacts are now being documented across marine ecosystems, from whales down to plankton. Underwater noise pollution has been linked to disrupting normal behaviors, masking communication, impairing feeding, and increasing stress levels; even causing permanent injury or death.
