6. Pete Townshend
Pete Townshend is most prominently known as the guitarist and songwriter for The Who. After years of loud concerts and music, Townshend's hearing deteriorated greatly; he has tinnitus and partial hearing loss. Have you ever opened up the Guinness Book of Records and seen the record for the loudest concert ever? It was at the Charlton Athletic Football Club in London on May 31, 1976, and guess who was doing a gig there? No, no, not The Guess Who. It was The Who. This and hundreds of other concerts The Who played have contributed to Townshend's hearing loss over the years. He consulted with an audiologist in 2010, and it was suggested that he use an in-ear monitor, which is especially useful for musicians.
Fun fact: Pete Townshend has never had formal music training; he’s completely self-taught!
