I once heard (I forget where) that when you're around loud noises, the tiny hairs in your ears that filter sound end up being flattened out, causing your ears to ring after the loud noises are gone. Once the hairs rise back up (which can take a few hours to a few days), they can filter sound again and the ringing goes away, although it takes longer for the hairs to rise back up (and eventually, less of them will) the more you're around the loud noises. I'm not sure if this is true and/or if I butchered the explanation that I received at one point in my life.

I've been in bands since I was 13, playing guitar and drums. Even when it's completely quiet, I can hear some ringing real faintly in the background, but it's never really quiet enough for that to happen all that often. I don't really trust myself with mixing recordings though haha.

I can hear when electronic equipment is turned on, off, or left on, which is kinda cool I guess...it's like being a super hero.
 
I spent three years installing stereos in cars, the last two years was nothing but big ghetto jammin systems for drug dealers in the Tampa Bay area. I built a lot of systems that would play music at 150db. That is loud enough to make your vision go blurry. The loudest system I helped build did 162db with the doors open, it would ne louder with the doors closed but we were worried about breaking glass so we never tested it with the doors closed. It sucked the air out of my lungs for the few seconds I listened to it.

What is scary is that the customers never wore hearing protection, I was the only one in the shop to do so.

The shop car actually set a world record at 174.5db with only 5 15's. It had about 5000 watts going to each 15 and 24 batteries to power it. All of this was crammed into a Geo Metro.

I worked in a sawmill once. I didn't wear earplugs one day and it took 2 days for my hearing to come back. I spent 2 years setting up sound, lighting and video for big concerts and never went without hearing protection. Some people never had any and always left with a headache.

I am now a truck driver. The company just issued me a brand new Volvo to drive, I was in a Freightliner. The Volvo is so quieter that I'd actually quit if they told me to drive another Freightliner. The road noise reduction in the Volvo is so much better that it makes you wonder if Freightliner is just living off their name.

BTW, I'd love to see Sage Francis, and will when I get the chance.
 
sorry to be a bit random.. but this just made me think of how helpful stemcell research would be for deaf people.
imagine impllanting the tissue to repair/replace it..
wow, but then i guess you could do it with every organ in the body and live forever... wow can of worms!
lol

BOOOO stem cells research is immoral, stop killing the innocent babies! :p
 
the against me show is coming to town on monday. i might have to check it out. sage francis is decent, but against me is one of my favorites. i'll be sure to bring ear plugs...
 
How does the db system work exactly?

For example, when I'm on the bus I can barely hear my iPod, even when turned up to 'high' decibel levels. And yet, when people talk to me on the bus, i can hear them loud and clear. So is their talking more damaging than listening to the iPod?

Here's the bit - and headphones are a good example. Everyone has been on one end, or another, of somebody listening to earbuds getting asked a question... When responding, they yell to the other person, completely unaware they're yelling. We automatically adjust our voices to surrounding noise levels. Ever notice that after 5 minutes of talking on a train, jet, concert or bus, your voice starts to get raspy - but you can talk all day at home? Cause you're being that much louder in order to communicate.

I can't remember the medical term - but people do it all the time. It's why people tend to crank up the stereo for a good song, then have to crank it up a little louder an hour later for the next good song, ect...

Another example is when you listen to the radio on the highway at a reasonable volume - but when you get home, and start the car the next day - it's always too loud, and you need to turn it down.

A change of 1db is the smallest amount of change a person can hear

A change of 10db sounds like it is either half of twice as loud as before.

Doubling power into a stereo system will only get you an extra 3db, if you aren't near the speakers limits(compression)

Doubling the amount of speakers without increasing power will only get you an extra 3db.

It takes quite a bit of power to make a lot of noise.
 
It sounds like Tinnitus. I get this in my right ear in the form of a high-pitched static noise that's really annoying. It's more prominent when I'm in a quiet environment.

I'm going to the doctor soon to check out what I can do about it. It's more of a nuisance than anything else and it comes and goes...or maybe I'm just getting used to it :confused:
