Sharks are fierce ocean creatures with strong jaws, sharp teeth, and a great sense of smell. But, even though they are known to be top predators, studies have shown that there are sounds that sharks don’t like.
Sounds that Sharks Don’t Like
Scientists have conducted research to find out which sounds sharks dislike. One sound that sharks seem to hate is the low-frequency pulsing sound of killer whales. Since orcas are predators of sharks, it makes sense that their sounds would scare sharks. A study found that great white sharks quickly swam away when they heard orca sounds, even if there were no orcas in sight.
Metal Chain and Shark Repellent
Another sound that can repel sharks is the sound of a metal chain dragging on the ocean floor. This sound is similar to the sound of a struggling fish, which might attract a shark. However, research shows that when sharks hear this sound, they are less likely to approach.
High and Low-Frequency Sounds and Shark Attraction
High-frequency sounds produced by a boat’s propeller or a swimmer’s kicking legs can attract sharks, while low-frequency sounds such as the sound of waves or a whale’s song may be less appealing.
Music and Shark Behavior
Moreover, some music genres can affect shark behavior. A study found that when heavy metal music was played, sharks became more agitated and less likely to approach a baited line. However, when classical music was played, they were more relaxed and less likely to approach.
It’s important to note that these sounds are not guaranteed to avoid shark attacks. It’s necessary to be cautious and aware of your surroundings when swimming or surfing in the ocean and take necessary measures to reduce the risk of encountering a shark.
In conclusion, sharks are feared predators, but research suggests that certain sounds are unattractive to them. Low-frequency pulsing sounds of orcas and the sound of a metal chain dragging on the ocean floor are examples of sounds that sharks avoid. High-frequency sounds may attract sharks, while low-frequency sounds may be less appealing. Nevertheless, there’s no way to guarantee avoiding a shark encounter, so caution is advised in the ocean.
