What is the NRR (Noise Reduction Rating) for this model?
1965657
Not very high. These are cheap, Chinese made ear protection. I use them with my lawn mower and other stuff like that in the garage. If you need some serious noise cancellation for stuff like shooting guns, or anything construction related, then I would buy a different pair.

Don't know, But I shoot large caliber rifles and operate very noisy equipment with them and they work as good as my expensive pair. You will not be disappointed at this price. Hope this helps!

Just for the record, earmuffs don't HAVE decibels, they ATTENUATE (reduce) sound pressure levels. This reduction is expressed in dB by what's know as the NRR (noise reduction rating). For electronic earmuffs, this one is pretty high at 25 dBs - if the manufacturer's rating can be believed. The thinner, lighter ones are usually around 22 dB, and the very expensive ones can be as high as 30 dBs. The non-electronic ones are much cheaper and reduce sound by much more than the electronic ones (except for the super expensive ones).

I couldn't give you the NRR number, however, I worked in a very crowded area with echos and these work amazing at blocking outside noise and allowing you to hear the radio traffic. I've used multiple designs and I have always continued with this one. I have only ever had one defective one that was muffled sound and it was immediately replaced. The only "downsides" is if you are extremely active and have little ears then these may fall out. It is very difficult to hear out of the ear that you have the plug in, but that is because it is doing it's job properly and blocking the outside noises. It does a great job!

I do not recall, but it has performed better than the original equipment and is much quieter.

There is not much background noise from the unit. It is very clear. We use it daily on the back porch and have no issues.

The unit is quiet, and will not cause you to use hearing protection. Compared to all of my other equipment, it is the least intrusive.

While I dont have the exact specs, I can tell you that its nearly silent when it switches on. I have it sitting on top of my unit sucking air straight out of the receiver vents and its very quiet. I really don't think noise is an issue with this thing. Doesn't even produce vibration noise.

The noise level is very acceptable, considering the fact that you have no electric. Solid generator. Bought mine 6 yrs ago, money well spent.

It does make some noise when running but is much quieter than previous units I have owned. I would estimate between 40 and 60 decibels when operating

Not sure on a rating but it is very quiet. For a while I had squealing problems on the exhaust blower like something was rubbing and I would use silicone spray on it. I was going to try and take it apart and fix it but all of a sudden it stopped making the noise.

I cannot say for 100% certain. It seems reasonably quiet (certainly NOT silent), but I'm running it in a server room with a couple of servers that kick out major decibels, so I don't have an accurate sense of this machine's noise level. Sorry.

It is whisper quiet. For goodness sake, how can someone else be the judge of your white noise needs? It's 30 bucks! Buy the d*mn thing and try it for yourself. If you don't like it you can sell it again here.

The one I purchased and installed is relatively quiet. I don't notice any noise. I'm happy with the purchase.

Don't know--haven't had any problems or noises with mine. Call for tech support.

Not sure, but with the Nitro piston it is quiet and powerful. Unbelievable quiet I've been told by people with other brands.

I do not have or ever used a model XTR-140 0r 145---The XTR-265 I currently use in one of my vehicles is well worth the moneyI paid. If you have a companion that is annoyed with the sound of loud units, the 265 is what you want, it lets you know in a more refined way. Has some false signals but most of the time, it is your best highway friend. I like Whistler Detectors.

The factory setup is virtually noise free. Put the stock unit back on truck. I will probably put a good filter in the box & leave it alone. Wasted $260.
