This video and article contains minor spoilers for A Star Is Born.

One of the central storylines of A Star Is Born is Jackson Maine’s (Bradley Cooper) struggle with hearing loss and tinnitus, made worse by the fact that he’s a famous musician who performs live concerts and exposes himself to loud sounds on a daily basis. In the film, Maine visits an otolaryngologist, played by Cooper’s real otolaryngologist, Dr. William Slattery, who advises him to wear in-ear monitors to help block sound and manage his condition. Last week, Dr. Slattery invited us to his offices in L.A. and talked us through some of the science behind Jackson Maine’s condition.
