As I have said before I thought that Tinnitus was was quite "normal" because I have had it for so long. To counteract its psychological effects on me, I like to have some sort of back ground noise. In the shed I always have to radio on as well as when driving. If the volume is really low, it drives me mad so I elevate it so I can "listen" to what is being said. I have never been a head banger so top of the scale volumes are not the norm. Even sitting here at the computer I always have music (from my own stocks) playing continuously at a low level you can't hear it at the room's door. Total silence is real torture!! If you wanted to interrogate me, it wouldn't take long to get what ever info I might want, by leaving me in some quiet place
I don't like the way that a day of working with noisy machinery follows you home after work and does affect you insidiously. But there are some noises that are worth the exposure. I was in city traffic years ago and stopped at a red light at the bottom of a long hill. Next to me was a single axle International prime mover with a Detroit Diesel motor. As we waited for the light to change I wound down my window to let in as much "music" as I could when the truck let rip...I was not disappointed....what a sound. It was totally wasted on my wife who only heard "noise" I was hearing a "symphony"Just do it!
Kind regards Rod

After working in the printing industry for 30 years I have a touch of industrial deafness too. The worst machine to operate was the paper folding machine. We had one of ours tested and were told that operating it was on par with standing near a 747 on take off. I never wore ear muffs. My tinnitus started a few years ago after I was caught in an office trying to shut of an alarm system. Like Derek I've learned ways to live with it. On an other note, I have trouble with my TV in that I find myself forever turning up the volume to hear the voices then having to quickly turn it down when the music/action starts. On my old TV's I could access a control panel and up the treble and turn down the bass. The new TV's don't do that now. I went out and looked at Sound Bars but they don't have that functionality either.

Sorry Alex, but here's a bucket of cold water for you. Now I forget the actual specifics, and BobL can supply them, but these muffs are designed for a loud single impact and not for loud continuous noise (I know - "what's the diff?" but apparently there is). As such you may be inadvertently damaging your ears.
The best muffs going are the Peltor H10 (Class 5) which can be supplemented with in-canal buds for super-noise. They are available in conventional, behind the neck, and off the hard hat styles.
This can sometimes be due to lousy mixing when the DVD is produced. From time to time we see a DVD that is very difficult to hear the speech clearly on - most recent example was "Collateral" with Tom Cruise and Jamie Foxx. In fact it is probably the worst example so far. Had the centre (Speech) channel right up but still impossible to understand some low volume speech. Just mud, but most are quite clear.

Shooters muff's have noise reduction ratings (NRR - a general algorithm covering most industrial frequencies) anywhere from around 22dB (small arms) through to 34dB (about the maximum possible without going to a deep sea divers helmet). To improve noise specific to shooting frequencies, some use noise cancelling electronics - this may or may not help in a workshop situation.
Here's a recent review of 10 of the supposedly better shooters muffs https://www.shootingandsafety.com/be...-for-shooting/
8 of them use active noise cancelling but the Glock (NRR 26dB) and the ClearArmor (NRR 34dB) use no batteries.
With a NRR of 34dB I reckon the ClearArmour could make a useful WW muff.
The best muffs going are the Peltor H5 which can be supplemented with in-canal buds for super-noise. They are available in conventional, behind the neck, and off the hard hat styles.
The 34db NRR of the Peltor H10's are achieved by a combination of acoustic absorption and higher pressure to the side of the head so although they are effective at noise reduction they are not the most comfortable muff. A power tool that generates say 90dB at the operators ear only needs a ~25 dB NRR muff to get that down to under 80dB and the provide sufficient hearing protection.

Interesting thread. I get tested by work every two years. Not wishing to hi-jack the thread, I’ll Just mention that i’ve just experienced similar between an optometrist in a retail outlet and an opthomologist specialist and it was an expensive and wasted set of glasses.

The muffs I use are 3M Peltor Optime 105, which have a 30dB noise reduction. I purchased a second set recently from Amazon (USA) for $39 (AUD) including shipping costs.

At my last hearing check we discussed Tinnitus mainly because the Audioligist's partner had it and she wanted to know how I Ignored it so well because her partner couldn't. She then offered me a book to read on it which I refused and she wanted to know why. My experience is to never read or inquire about Tinnitus and just ignore it. I might be lucky because I have always been able to compartmentalise (is that a word?) my life, leave work and never think about it sort of thing so I think that helps. Mine never varies during the day and as I have gotten older it continues to get louder. I first became aware of it when watching an ABC doco that was discussing it and the then current research, at that time they had found that it went away for a few minutes following an injection of adrenalin IIRC. Why did I get it? I think it was from one session of shooting in the army where I shot something like 400 rounds without ear protection but then the ear protection was so poor it would not have mattered.

Even though they have different NRRs, the Peltor Optime 105 (full name is Peltor OptimeTM 105 - H10A, NRR 30dB*) has the same frequency attention profile as the Peltor 10HA (NRR* 34dB) and are exactly the same muff.
* The reason they have different NRR is their NRRs are calculated differently.
From the 3M website.
*The Noise Reduction Rating (NRR) may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided. The 3M™ Peltor™ Optime™ number (105) is a 3M guideline for the maximum time-weighted average A-weighted exposures in which the product, when properly worn and in good condition, can provide adequate protection to meet OSHA hearing conservation guidelines. However, the user must make sure that the specific earmuff and style selected provides appropriate protection. To be effective, the hearing protector should be used within a hearing conservation program that also includes noise level assessments by qualified personnel, training, audiometric testing and engineering controls. 3M™ Optime™ recommendations are based upon testing per Method B of the most recent ANSI standard, S12.6-1997 (R2002). Method B provides data that approximate the upper limits to attenuation that can be expected for groups of occupational users. Properly trained and motivated individuals can potentially obtain greater protection.

which to buy
For the sake of simplicity, is it safe to say that "Peltor Optime 105 (full name is Peltor OptimeTM 105 - H10A, NRR 30dB*) or Peltor 10HA (NRR 34dB)" is the best muff to buy? If one were to spend more, is there better?
I have a pair already, but another sits in my cart for the next order.
I use my tools 4 to 6 hours a day. The DC is on and I wear my Peltor Optime 105's every time. At first they were hot and made my wifes screeching hard to hear, but over time one gets used to the heat....

Without wanting to bog this down into a discussion about muffs.......
My Peltors are labelled 3M Optime 5 Class 5 H10B 290 and the label looks like this one but mine say 5 where it says 5+ and H10B where it says H10A. I presume that the 290 refers to 29db reduction (another pic mentioned 29db). I presume that "A" refers to overhead and "B" refers to behind the neck (which allow a brim hat for lawnmowing etc).
Anyway, they're damned good! One aspect that I like is that even while they cut the noise way down, speech etc from 5 metres or more away is still reasonably audible, which explains why woodpixel still gets the screeching (I'm telling).

My first hearing aids.
I'm really humbled at all the replies and feedback this has generated.
When I posted this I was expecting maybe four five comments.
But wow the amount of feedback is amazing
thank you for such great replies.
One for me stands out the most but they we're are all great.
Derek , thanks your story was humbling.
Like others I've learned now to live with my tinnitus.
Some days are good some bad but mostly good.
I will be doing a lot more research towards hearing aids now.
Thanks everyone Matt

I have had impaired hearing for most of my adult life my career was not that different to yours I now happily wear my heasring aids all day at work and when I play with any sort of PA they go back in there little box in my bag,yes about 5k .
The technology is pretty awesome and they fo rsske dome getting used to.
The funny thing is when people fo notice them thry seem surprised that I have had them for so long.
Still cant hear swmbo most of the time.
Cheers Steve

That is called "selective deafness"
