About a month ago, I woke up and found that I was suddenly half deaf in my left ear. My hearing was also obviously impaired in my right ear, but not as much as the left. In addition, I could hear no deep bass in either ear. I have no idea what could have caused this. My hearing response got lower and lower below about 200Hz and dropped suddenly after 100Hz. I could hear absolutely nothing at any volume below 40Hz. I used to be able to hear clearly down to 15Hz. I saw a doctor about it and finally was referred to an audiologist, who I saw a week ago. The audiologist tested various frequencies, from 250Hz up. She did not test below 250Hz, but she said that based on my test, my hearing was better than most 5-year-olds'. To this, I told her that most 5-year-olds must be deaf (expletive), and asked if she considered my deep bass response to be important. She said to come back in a week if I'm still having problems. I had been having the same problems for over 3 weeks at that point. My hearing has slowly recovered, but it is not anywhere near what it used to be. It's like I'm hearing my whole life through a cheap pair of "detailed" or "neutral" headphones, and it causes constant misery. My hearing response constantly changes. Sometimes I can barely hear what people are saying over the phone, and sometimes it isn't too terrible, but it never reaches what it was. It seems like I shouldn't be complaining. If my current hearing tests so well right now, then my ear must have been more golden than the pot at the end of the rainbow before I lost most of it. Now I'm normal, I suppose. I don't really know who to ask, other than a community of audio lovers. What should I do, Head-Fi? edit- I don't know if this is in the wrong section; I'm a nub. My ability to hear low frequencies has recovered the least. The rest of my hearing is bad but still existent.
