Can Fish Hear & Other Noise Exposure Facts?

When I was visiting a supplier in Japan, our host was extremely proud of their koi pond and wanted to demonstrate something. He took us to the pond’s edge and clapped his hands. From the murky depths of the pond emerged huge koi breaking the surface with open mouths. As their reward, he tossed them a handful of fish food.

While everyone else was enamored with his ability to have trained the fish, I was awestruck with the fact that they could hear the sound of clapping deep down into the pond. No wonder dad kept telling me to be quiet or you will scare the fish away.

According to the National Wildlife Federation fish don’t have ears that we can see, but they do have ear parts inside their heads. They pick up sounds in the water through the lateral lines that runs down each side of its body and transmitted to their internal ear.

While human auditory abilities may not be as sensitive as the rest of the animal kingdom, the inner workings of our ears are very sensitive easily damaged. Listening to loud noise for long periods of time can damage the hair cells in the inner ear. Noise-induced hearing loss usually develops gradually and painlessly. We live in a noisy world and hearing loss among Americans is significant. According to the Center for Hearing and Communications, approximately 12% of the U.S. population or 38 million Americans have a significant hearing loss.

For 30 years EXAIR has been designing and manufacturing compressed Super Air Nozzles, jets, knives, and amplifiers that significantly reduce sound levels and compressed air costs. Protect your hearing as well as your employee’s and save money by contacting our application engineers and they will show you how.
