    Hi all,

    I have been flying my S1-S for several months. We had to pull a jug for a worn valve guide. In the break-in period that followed, I spent a couple of hours at full throttle. My ears are still ringing. I actually went to an audiologist today to see how much damage I had done. Conclusion is that I have to figure out how to reduce the cabin noise level. I'm already using silicon ear plugs under a David Clark with the Oregon Aero upgrades.

    I currently have the factory 4 into 2 short stacks. I talked to the folks at Raven who have a four into one, but they said that wouldn't really help the noise level. I am looking into cross over options. I also understand that in Europe, mufflers are required for many aircraft.

    Anyone have any good ideas on how to save my ears?

    Regards,

    My S1S has the sky dynamics 4-1 and is also LOUD. I am using clarity aloft under a helmet and found the noise level to be much more tolerable. The hearing protection was the top reason for going to the helmet.

    I started using a clarity aloft and that made a huge difference. Putting it under a helmet would help more. Or even toss a DC headset over top, or just a plain old pair of passive ear muffs. lots of easy answers but having both in ear and over ear passive noise reduction is the best bet. ANR doesnt perform well in extremely loud cockpits as the cancelling signal clips.

    The noise level in a Pitts is about 120db = permanent hearing damage after 30 minutes. I always wore foam ear plugs along with my David Clark headset. The BF9-2 is not nearly as noisy as a Pitts, and does not require foam ear plugs.

    I use CEP-USA earbuds wired into an ANR headset. I think that's about the best protection you can get.

    Telex 50d works well. I modifeid a bonehead gunner to accomodate it.

    HGU-33 with custom Bose x noise cancelling.
    I understand some taller folks have trouble fitting a full sized helmet inside a canopy.

    Bose A20 is not overwhelmed by the noise in mine. It works really well.

    CEP with my ANR helmet was my answer to a similar problem in my Skybolt. I can actually turn the radio volume down now...

    Best solution is ANR headset with CEP's I have a unique job and have tried every major ANR headset on the market (bose A20, lightspeed zulu, lightspeed tango, clarity aloft, DC X, AKG. The Bose A20 is the best. But when coupled with CEP's nothing touches that combo.

    The ANR cleans out the low freq. the ear plugs take out the high and knocks the low. When you put ear plugs in you can't hear the radio so you need to turn it all the way up. The CEPs are basically ear plugs and you don't have to jack the radio up.

    I used the Halo headset in my S1 and found it to be as quiet as my Bose in my Pacer ; I actually think the Halo's are quieter than the Bose overall. Might be worth trying out.
    I found the silicone ear plugs do not work as well as foam. I recommend trying foam ear plugs and see if you have the same issue. The Halo headset uses foam btw.

    I'm wearing a D/C headset in a cloth helmet. If I use earplugs, I can barely hear the radio. It's a comfortable enough rig but not very effective in noise reduction. Unfortunately in my younger days I abused my ears with loud motorcycles, airplanes and Army helicopters. Flying Cobras for a tour in Vietnam I returned to my "back in country" physical to be told by the flight surgeon, "Do you know you have a profound loss of hearing"? I said what?

    At this stage of my life I need to protect what little hearing remains so I use the Bose 20 in the RV4 which does a great job in that application. In the Pitts the flights only last about 30 minutes but it does ring your bell. I'm now leaning towards the Bonehead solution and would like to know how comfortable that helmet is from the guys here familiar with it.

    Thank you for your response.

    Cheers, Hans

    So how do you work the CEP with the Bose A20? Do you cut the wires that provide radio signal to the speakers in the headphones and splice in the CEP? Or just leave the bose headphone jack unplugged and plug in the CEP instead? Very interested in trying this combo. I'm flying open cockpit with Lightspeed Zulu AND foam ear plugs and it absolutely sucks.

    Thanks
    Paul

    I was a singer in the 70's, before that CL model airplanes, was taught how to fly in the 60's and 70's,where yelling over the noise was the norm, 2,000 in Twin Beechs, DC-3, B-25, 3,000 hrs in 727, then I started flying the Pitts Specials. Loud, noisy vibration wise, but made so much better by a helmet with an ANR system. My stuff is old, I'm checking out the systems mentioned here.
