Historically, experts tell Yahoo Life, noise pollution meant “unwanted sound.” But that’s subjective. “My music could be sound to me and noise to you,” Rick Neitzel, a University of Michigan professor of environmental health who researches auditory exposures, tells Yahoo Life. Although health hazards related to noise had been recognized since 1968 in the U.S., the definition wasn’t expanded to “unwanted and/or harmful sound” until 2021.
