4 I convinced my parents to get me a music device with headphones when I was eleven. When I was fifteen, I started going to conc
erts at indoor arenas and large amphitheaters. At the big concerts, you could always find me next to the speakers. A year later I was also going to all-ages shows at clubs—and you know where I'd park myself. After a concert or a club gig, I'd occasionally notice ringing in my ears afterward. But by the next day it would be gone. Yet that post-event ringing gradually got louder and louder, and it took longer and longer to disappear. Then one day last year I realized that the ringing was 24/7, except when I was asleep. I also had to face the fact that, more and more often, I was asking, “What did you say?” in conversations. Based on paragraph 4 of the passage, what conclusion can the reader make about the author?
