In today's episode, Dr. David Corey, Professor of Neurobiology at Harvard Medical School, answers Adam's question, "Why are loud sounds bad for our ears?" The answer is found in the tiny yet complex structures called "hair cells" within our ears that translate mechanical vibrations into electrical signals. When loud sounds cause these hair cells to move violently, they can tear the tiny filaments that keep them stable or, more seriously, uproot an entire hair cell. Join Adam as he learns about the short- and long-term effects of loud sounds on our hearing. [04:24]
