hearing protection

Hello there

I have a NAC intercom helmet with earpuffs (Peltor H540A) and a mic/speakers/radio connection.

In my early days of PPG 10+ years ago I didn't wear much hearing protection and probably suffered some hearing loss.

Now, I fly with this helmet along with ear plugs (German made high quality foam).

However, I still feel that the noise level is too high.

Does anybody know of any ear muffs (preferably w/radio connection) that is better in terms of protection?

Cheers!

Bjornar

Hi Bjornar, looking at your picture it seems the NAC is based on the Peltor Optime III ear cups, as is the Microavionics kit.

I haven't found anything better then these, the quoted attenuation rating is 35dB, so you can compare others to this.

Cheers, Alan

The Peltors attached to my helmet have 35 dB SNR. For a discussion about SNR (Single Number Rating) vs NRR (Noise Reduction Rating), look here:

The ratings are different (and in general the SNR rating gives a higher value than the corresponding NRR rating).

My 540As (which presumably are the same as the Optime IIIs), seems to have a very high rating (34 dB SNR for the Helmet Version). I have not been able to find any higher rating than that. But I will continue to look.
