Be quiet or you’ll scare the fish. How many times have you heard that? But is it true or is it a myth?
Yes and no, according to fishing pro Tom Redington.
Since sound doesn’t travel well between air and water, loud talking or screaming will be barely noticeable to the fish underwater. They won’t get spooked or scared.
However, sound that occurs underwater is loud and travels fast. So jumping up and down in a boat, especially an aluminum boat, is loud and can spook the fish. Even dropping pliers in the bottom of the boat can scare fish.
