Jay, I have a Husqvarna brand safety helmet for logging ops. It has a plastic "Lawrence of Arabia" cape thing on the back of the helmet to keep sawdust and debris from going down the back of your neck. It also has a metal mesh flip up visor to protect your eyes. It has attached muffs that can fold up out of the way or just pull them away from your ears and they snap into an outer position. Then to prepare for making noise you just push in on them and they snap over your ears. The muffs are pretty effective. I have a 32 inch bar Husky with an engine like a small dirt bike and this sucker is loud. If I were to use it for long I would sure want to stuff the foam inserts in and use the muffs too. Id your Stihl like this? I haven't seen other brands besides Husky.
NOTE regarding buying plugs, muffs, etc. The NRR (Noise Reduction Rating is not LINEAR. It is logarithmic. It gives noise reductions in dB. So if you see one set of muffs listed as 26 and another set at 29 don't be fooled. the higher rated set is not just a little over 10% better. Each 3 dB is a doubling of power level. A set with a NRR of 29 cuts the sound down twice as much as a set rated at 26.
Our ears are also logarithmic in response and things that sound twice as loud actually have a much greater difference. Our perception of the loudness of sounds is not accurate and judging when sound is loud enough to harm you is not easy. Netter to be safe than sorry.
Oh, by the way... When life hands you lemons, get some tequila and salt and call me!
