Tinnitus since age two. Only advice I can is give your ears plenty of rest, avoid caffeine + coffein. Get noise sensitive plugs n use at all times + ear muffs for extra noisy places. /Bo

Well, Guys,

Welcome to the hazards of noise! I've had tinnitus for many, many years and it never stops. It does, however, change in apparent intensity and annoyance but in no predictable or consistant manner. Mine was caused by being exposed to the noise of many Dyna-Jets and, especially, standing within 15 feet of Aeromarine's 210 lb. thrust, 8 in. pulsejet. I was there to help make adjustments in fuel flow so that the engineers and technicians could record all the results. None of the others wore any kind of protection but only Jerry Nolin admitted to his hearing damage. All this took place in 1950-1952.

About 20 years ago, my ear and hearing doctor warned me that ANY exposure to loud sounds can cause damage, its severity and permanance depending on the actual intensity, frequencies, and duration of exposure. In fact, he assured me that damage is cumulative because the sensing "hairs" that trigger our brains to perceive sound break off and never regrow. As others have noticed, temporary tinnitus and/or deafness also takes place but, though not always apparent at the time of exposure, permanent injury ALWAYS results. The doctor also warned me to wear hearing protection any time ambient noise is loud enough to cause people to raise their voices to be heard. In my case, that was almost all day, every day at the various machine shops where I worked during my career.

Avoidance of caffeine, he advised, is of help in keeping down the increase in severity of a person's tinnitus but it does not reduce or stop the conse-quential hearing loss. As has already been said, there is no known treatment or cure for this kind of loss. Sorry.

Jerry

Yea I have noticed the damage depends a lot on the design. Some are incredibly peircing with very sharp wave forms and others have more rounded peaks that make a lot of difference in the acceleration / deceleration.

Its something like the difference of jumping head first onto a concrete floor or jumping head first into a swimming pool.

A TP-180 70 lb thrust engine running at 5lbs thrust will produce much lower intensity and overall sound energy than a dynajet running at 5 lbs thrust. If you want a quiet pulsejet make one really big that runs really low.

Talking like a pirate does not qualify as experience, this should be common sense, as pirates have little real life experience in anything other than smelling bad, and contracting venereal diseases

Thanks everyone for advice etc. It looks like I have permanent ringing fortunately it's faded or my brain has mostly tuned it out, it's sort of a faint hiss now. I now only notice it when it's really quiet or I've first put my earmuffs on before working. If there is some noise in the background or I'm doing something I don't notice it.
I'm definately much more sensitive to noise, stuff that never bothered me now has me reaching for the volume knob or earmuffs.
Thanks once again.
Cheers

Think accumulative: Give it some more damage and you will start to loose the communications with the back ground noise. I have found my self so bad that I have to look people in the face in order to know what they are saying! I found over the years I can lip read good! I can now turn the volume off on the TV and know whats going on. At work we have 36 swamp box coolers running. Lots of machine running .. People talking.. Sound system piping music into the room!..

White noise or Pink noise of the right sort can blind me audiably!!!

When in the Air Force , I had a supervisor send me for a hearing test because I missed phone calls. I could not hear it over the equipment white noise. They said I was fine as when I was in a sealed sound proof booth with head phones on, I could hear around the 3oohz to 7oohz normal voice tones...HAAAAAAA! The med tent STAMPED ME servicable......

Pete Twonsend of The Who has become an advocate for hearing safety.
Apparantly he has severe tinnitus now.

http://en.wikipedia.org/wiki/Tinnitus

http://www.ata.org/home/inthenews.html

http://www.hearnet.com/about/about_acco ... ents.shtml

I have a set of the Peltor Worktunes earmuffs.

http://www.elvex.com/com-muffs.htm

http://www.nextag.com/hearing-protectio ... earch-html

I really like them. The problem is when I am just using a die-grinder
for a minute, or just blowing off the lawnmower with a leafblower
real quick, or other situations where I am not exposed to uncomfortable
levels of noise, or it is only a little loud for a very short duration...
because then I don't want to stop what I'm doing to go get earplugs
or earmuffs.

When I pickup my angle grinder, the earplugs and safety glasses are
pretty much automatic... but some tools I just forget that they too
are worthy of caution.

The key is religious use of hearing protection. It might be wise to have
a pair of earplugs on a string so I can hang them around my neck any
time I am in my Laboratory, even if I don't plan to use power tools.

I have some hearing loss, and mine is also of the type where I cannot
pick out the conversation I want to hear from the background noises.

It also seems like I now hear sounds from behind me too strongly, and
I have a hard time hearing what's in front of me when there is sound
behind me.

I'm also an extremely light sleeper, so there is one possible slight benefit,
but certainly not worth the hassles associated with hearing loss.

This thread (or maybe a similar post with a summary of useful info from
this thread) might be worthy of a "Sticky".

Maybe a topic area dedicated to safety?

Likewise. If I'm in a crowd of people who are all talking, or an environment with a lot of background noise, I'm effectively deaf. The work doctor can only spot a slight default in the hearing in one ear, though, and I've had that since I was 7 or so. My hearing loss, I believe, was caused by too many motorcycles (screaming motors and helmet noise) and too many punk concerts.

That's because you've had you head up to the tailpipe so often you've blown holes in the backs of your earlobes :)

hearing

Due to the constant type of noise emitted by the P.J. I would like to try out a set of Noise Cancellation type head phone. Has anyone out there tried them?

I try to keep my head out of my tailpipe!

BTW, when I first started to learn sign language, my instructor (who knew
a thing or two about audiology) immediately guessed that I hear unequally
from right to left ear when I told him I have trouble distinguishing what I
want to hear from ambient noise.

Apparantly unbalanced hearing is common for people with this type of hearing difficulty.

Prices on commercially available ones (Bose, Sony, etc.)
Have come down quite a bit... probably cheaper than building
a set on your own.

Hearing, or lack there of.

Post by Rossco » Wed May 16, 2007 9:59 pm

Hey Guys, sorry to hear there is so many of us in this catigory.

It isnt a joke, newcomers, do something about it now!

I am bad in one ear especialy, and listen to people with my head turned one way, (some pick up on this, others probably just think im strange)
and the family can watch or hear the tv from down the street.
Mine is industrial deafness from machinery, tools and mostly large rifles.
Ofcourse, pj's will not have helped at all, and in the past, i have been careless at my own expence.

I didnt know about the caffeine!? bloody hell, next youll be saying i have to give up beer and smoking too! No wonder I dont likes doctors.
