My right ear doesn't seem to be as loud as my left ear, especially when listening to music with low frequency bass response. When I hum at a low pitch, I can only feel vibrations from my throat go to my left ear, not my right. This has been happening for the past several weeks, and I had recently been to a doctor to check my hearing, and he said it was fine. I think the major issue might be headphone use. I do use headphones moderately, but at low volumes. An issue I would think of is the clamping force of my headphones might be too much for my head, thus blocking my eustachian tube. I tried the Valsalva maneuver, where you close your nostrils and blow air through your mouth, but this has not caused any changes in improving my hearing. I was listening to music on my headphones once at low volumes, and it caused my right ear to ring loudly for several seconds, and after that it had stopped being as loud as my left ear. Sorry for throwing this information out in such a random fashion, but I would really like to know what I can do. Being almost 15, I don't want to lose my hearing at such an early age. Would someone be able to tell me the next best course of action?
