Hi guys I dont know if this is the place to post this but this has been really worrying me so it would be great if you could help me out.
Recently I bought a 12 inch sub and put it in my car, and I noticed that after getting out of the car there would be a humming noise in my ears that would go away after maybe 30 minutes. I wasnt playing the music very loud (half volume, 70-80 db) and its only a single 12 inch sub, yet I get this humming noise in my ears after only 20 minutes of listening. I can listen to much louder things for hours (for example going to the movies, or listening to music without sub) and not get any humming sound in my ears, but when I plug the sub in I get this humming noise even from very low volumes for only short times. It would be great if you could help me out because I just spent 5 hrs installing the sub and I am worried that I will never be able to listen to it. Cheers.

70-80 db is the level of average talking. are you sure it is not louder?

Yep im sure and that is why I am so confused, I tested the decibels. Any ideas on why this might be happening or what to do about it?

Prolonged exposure to loud noises will damage your hearing.

Human beings do a lot of things that torture our ears. I grew up on a farm and we never wore hearing protection around all of the heavy equipment. I have friends that like to go to rock concerts. When I was a younger man I went to a lot of nightclubs. I have a buddy who had a high fever as a kid in a lost his hearing in one ear. As I'm getting older I can already tell a difference in what I can hear.

I think you can still enjoy this hobby in moderation. My rule is that I wear hearing protection anytime I'm doing something that looks like work (say when I'm running a saw to build a subwoofer box, or cutting grass). If I lose my hearing I want to lose it while doing something I enjoy. On days where I feel like cranking my subs up to clipping and hammering away at them I pull out the earplugs.

You might just have sensitivity. No two ears are alike. I hear thing my wife does not and I don't like loud things. Bit of a paradox since I love car audio...

Have you considered seeing an audiologist? If at all possible, to be on the safe side, I really think you should.

Just off the cuff (and based on nothing), I can't help wondering if there might be something about your particular sub and/or application...

...and the extent that others (particularly those with substantial car audio knowledge and experience) may or may not be similarly effected and/or find something unusual or unpleasant about the sound of your sub.

(I'm still grasping at straws here) tell us more about your sub; i.e. driver (and amp) make and model; enclosure internal volume; sealed or vented (and tuning frequency), etc.

On a scale of one to ten, how satisfied are you with the sound quality (and output) of your sub (and does it sound at all unpleasant or strange to you)?

This is what I came here to say. You should really consider seeing a physician to make sure there's no underlying issue that you should take care of.

...and, is this your first sub (and/or sub experience)?
Thanks a lot for the responses guys. This is the first sub that I have owned myself but not the first experience I have had with a sub, my friend has one and I listened to it in his car and got the same humming noise after but we were playing the music very loudly so I assumed that was the cause of it. I am a car audio noob so I apologise if my responses are vague. It is a 12 inch pioneer champions series sub in a ported box, and a GM-3300T pioneer amp. They are probably pretty old as I bought them cheaply second hand. I don't really know much more, I just installed it in the car, adjusted my head unit settings and started playing the music. It sounds great to me (I may be biased because this is my first sub and I may not know what they are supposed to sound like), however the bass is a bit quieter than I expected it to be. I would say that it sounds 7.5/10 to me. It doesn't sound unpleasant or strange at all. I dont really know anything more about it sorry. And I am going to go and see an ear doctor soon. Again thanks alot for your responses.

Actually to be more specific, I thought it was a sealed box when I bought it (i bought the sub and box together) but then a while after I bought it I realised that there were a few small holes drilled in the box, I dont know if this counts as ported or no.

We're all noobs in the beginning (or forever, if you're like me :D). That's nothing to apologize for.

It doesn't seem like your symptoms have got anything to do with your particular sub and application.

As for the few small holes drilled in the box, if that's literally what they are (i.e. shallow holes that are less than 1" in diameter, for example); no, those aren't ports (here's some info on ported/vented cabinets: https://en.wikipedia.org/wiki/Bass_reflex ). Also, a "sealed" (aka acoustic suspension: https://en.wikipedia.org/wiki/Acoustic_suspension ) cabinet is meant to be air-tight; so, to the extent that those holes might prevent the cabinet from being air-tight, you should do what you can to permanently fill those holes, for optimal performance, as such holes would likely create noise, reduced output, reduced power handling, and potentially lead to overexcursion ( https://en.wikipedia.org/wiki/Excursion_(audio) ).

Glad you're going to see a doctor soon. To be on the safe side, I suggest that you refrain from listening to anything likely to induce your humming symptoms until the doctor says it's okay.

Whatever happens, please let us know.

Best of luck.

I performed a google search and based on your symptoms WebMD says you have cancer with a few days to live.

My condolences.

The holes in the box are probably relics from a previous install. A port will look like a round tube (plastic, sometimes PVC) or a rectangular slot.

Have you noticed the buzzing after other noise exposure? Like running power tools?

Hahaha thanks for the responses and information, and no I have never noticed this humming sound ever before, however I have had ringing after listening to live music but that is a completely different sound. For the moment I am going to stop listening to the sub and I will see what the doctor says.

Following up on this thread. I went to the ear nose and throat specialist and he said two things. He first said that there was a lot of earwax in my ears which could have been reverberating due to the low frequencies and causing it, so he removed the earwax, and he said to test out the sub and see if the noise still happened. He also saw that my eustachian tubes (things that make your ears pop on planes) were also alot bigger than in most people, so he gave me some spray to treat that aswell. I got home and tried out the sub, and there was basically no humming in my ears, 1% of what it was before. So im realy happy. Cheers for the advice people.

Wow, that's awesome! You couldn't ask for a more benign diagnosis and simple solution. Thanks for following up!
