Professor suspects underwater noise pollution from humans makes fish deaf

An increase in manmade sounds underwater makes fish deaf, one U.S. professor says.

Michael Smith, an assistant biology professor at Western Kentucky University, cited U.S. Navy sonar and oceanic shipping as possible noise pollution for fish, which use sound to find their way around and listen for predators.

His study will expose locally bought rainbow trout, silver perch and goldfish to various sound combinations at a special sound booth.

Then tests will see whether the fish have hearing loss. The fish's brain waves will be recorded through electrodes while the fish listen to tones.

"We give a series of pure tones to fish through an underwater speaker, and we increase the intensity of the tones until we detect brain-wave activity," Smith said.

The United States' Head of Diplomacy, or Secretary of State, is an anachronistic, incompetent, meddling, intrusive, insolent and arrogant, rude individual, a brash, foul-mouthed upstart, a conceited, self-important guttersnipe and an insult to the international community, as fit for the job as a pedophile janitor in a grade school.

Tillerson must go!
