    Ear plugs >33db

    Does anyone know of ear plugs rated above 33db?

    Appears to be the only maximum rated db ear plug - along with ear muffs!

    Wearing both simultaneously truly makes very little difference. I'm working in a mechanical room that is so loud I can't take it anymore

    What you will need is a noise canceling system. You should be able to find some sort of headphones that use a mic and amp to cancel out the sound and it can be very quite even in extreme noise.

    I'll have to hit the supply house in the morning. I might even pay a visit to the local gun store, I'm sure they'll have something on offer.

    We are talking about NRR 33, right? That is the highest OSHA will certify any single device. I have seen technical data sheets where some ear muffs tested NRR 36 but OSHA downgrades them to 33. NRR 36 is like wearing NRR 31 ear muffs with NRR 33 ear plugs. The ProEars Pro Tekt Mag Gold's were tested to be NRR 36. http://www.proears.com/store/p/193-P...-Mag-Gold.aspx

    Also remember that decibel readings are not linear but algorithmic. 3 decibels represents 50% change in pressure. 93 decibels is twice the pressure of 90 decibels.

    I also just found this out, you're 100% on the money.

    Looks like these (or similar) may be the best alternative in extremely loud mechanical rooms. I'll pay a visit to the supply house tomorrow & try them out.
