Question

john has played his music loudly for years. now, in his 20s, he finds he has a continuous ringing in both of his ears. what would john probably be diagnosed with?

regardless of the disorder, john will ultimately require a cochlear implant.
tinnitus, which is a nerve - based disorder that has no permanent cure
damage to the pinna, which can be corrected with surgery
conduction - based hearing impairment, which hearing aids may be able to help

Explanation:

Tinnitus is characterized by a continuous ringing in the ears. It can be caused by long - term exposure to loud noise, like John's case. Cochlear implants are for severe hearing loss, not always needed for tinnitus. Pinna damage affects outer ear shape mainly, not typically associated with ringing. Conduction - based hearing impairment is about sound transmission issues, not ringing.

Answer:

B. tinnitus, which is a nerve - based disorder that has no permanent cure
