I have just started to really listen to classical music, and noticed a bad resonance at a certain frequency, thinking it was my headphones, I have tried another pair, and it is still there. It sounds just like a resonance of something, but inside my head. Using EQ, it is around 600Hz, and thinking that it must be me and not both headphones. So my questions are 1) Is this possible, 2) Is this common 3) How do I deal with it?
Hello,
I am not an doctor/ENT but as a hearing care professional I understand a thing or two about the hearing process.
1) yes, this is possible. To calm you down, this is nothing to panic.
2) Could you please try it just with a simple sine tone generator? Is this on both ears or only on one side? Does it have a certain loudness range where it appears? Is it at lower levels or higher levels? How "wide" is the resonant frequency (like the q-factor or bandwith of an equaliser)?
I remember the first week as an hearing care professional apprentice I wanted to check the audiometer. First, I thought the right headphone speaker was broken because I could hear a grainy, distorted ringing with different overtones @ 1 kHz between -5 and 25 db HL, but it disappeared at 30 dB HL and louder. I asked my instructor if she could hear it too. No was the answer. So I switched the sides of the headphone to hear the result. Exactly the same and I realised that there is something resonating in my right ear. With a tone generator in my case the "resonance" occurs from 996 Hz to 1002 Hz. Below or above those frequencies i can a hear a pure sine tone. Like I mentioned before, the resonance has a more grainy character, something like bit-distortion or a lowered sample rate via VST plugin.
It could be everything from the tympanic membrane (a little perforation or scar for example), ossicles, cochlear (inner or outer hair cells), or even just because of the shape of your ear canal. It could be also ear wax like others have mentioned, but personally I or my clients have never made the experience of a resonant tone because of ear wax, normally your hearing impression is dull or muffled, dependent on how much ear wax is in the ear canal.
3) Maybe these are otoacoustic emissions you are hearing. But if it really bothers you please visit an ENT or specialist nearby you for further investigation.
In general, I recommend every adult to visit an ENT at least once in their lifetime so he can check your hearing with a calibrated audiometer. This is nothing special and last maybe 10-20 minutes.
I hope this helps. All the best to you.
Stay focused!
