I am one of those people. I love music, and my hearing has recently been tested as "perfect", but I got the hearing test at the request of my wife because she thought I had a hearing problem. For me, everything is good until I am exposed to a loud environment. People around me can talk/understand each other just fine, but I get overwhelmed. After discussing my problem with the audiologist, he recommended a neurologist. I don't think there's a cure for what I have, and I've lived with it as an adult for 40 years. I just downloaded this app to my (Android) phone. I see that it has 10k downloads so far. I am looking forward to using it.
