Righto Chook I was doing some thinking while rolling silage with the loader last night. Is it possible that the Peltor earcups with the dual shell are relaying outside noises to me if the speaker is touching the plastic cup and speaker pressed against my ear, like the tin cans and string principle? I remember that when I put them in there was alot less room in there than with the Bilsom Viking V3 although they were physically bigger on the outside. Its like an exhaust that drones in your car, you think you can put up with it until you can"t anymore.My headaches are caused by noise not pressure. I have some Uvex earmuffs that I use and they will give me pressure headaches after 5-6 hrs, but man are they quiet.Is noise cancelling is in the microphone, ANR is a second speaker to cancel out sound waves?Can you have an open face helmet without the wind/engine noises transmitting over the radio? Can a windshield around the front part of the mic be used?Intercoms? Ideas? I would like to use VHF ( I have icom A6 ) and UHF too. Music input would be nice but not a necessity.I live in Augusta. Found your phone number in Tony"s radio topic. Do you mind if I ring you?Birdy - some of the new helmets are carbonfibre so they are a lot stronger for that purpose

Chooky is right with the hearing loss as I can vouch for that. You will not hear a lot of sounds like your family members or your mates, small children, or a noise in your gyro that is telling you it needs attention now !!!! So look after the hearing with the best protection you can and remember you are looking at $10,000 plus to try to get some hearing technology help each time you have to replace the previously procured devices. And the rebates from the medical insurances is a joke not even a tenth of the cost. I have had mine for 7 years and need replacements as they are not bringing the sounds to my hearing ability now. So I can be referred to the deaf old grumpy bugger now. : ;DThese hearing devices can not be used in your ear muffs or under any hat that sound bounces off as you get those squeals in the ears that drive you nuts.So if you have to pay $2000.00 for a top skidlid with the best hearing protection it is cheaper in the long run. Cheers Des GarvinG"day there Des, you are very correct about looking after your hearing & today there are a number of ways to have excellent communications with excellent protection ....hearing that is

Its like an exhaust that drones in your car, you think you can put up with it until you can"t anymore.A)Matt, yes. You want as much isolation as you can get between the outside of the helmet and your ears.Is noise cancelling is in the microphone, ANR is a second speaker to cancel out sound waves?A)The ANR (active noise reduction) is purely for your hearing. You are correct in that the principle relies on cancelling the noise within the ear cup. Any noise or static that the radio receives will still be heard. The microphone is another story. We have some tricks to reduce the wind noise but again the Flycom excel at this by using their rubber "beard" which encloses the microphone and your mouth within a small area. The downside is on a hot day it can get uncomfortable. Everything in aviation is a compromise.Can you have an open face helmet without the wind/engine noises transmitting over the radio? Can a windshield around the front part of the mic be used?A)See above.Intercoms? Ideas? I would like to use VHF ( I have icom A6 ) and UHF too. Music input would be nice but not a necessity.A)Hmmm- We have a station owner who also requires the VHF/UHF combination and for him I used a Micro avionics system. It takes a bit of setting up, is not cheap and you need separate PTT switches for each radio. The other issue here is that you also require the Micro avionics helmet as part of the solution. I live in Augusta. Found your phone number in Tony"s radio topic. Do you mind if I ring you?A)No I don"t mind. I am home tonight.Regards....Chook.
