James Robinson wrote: Our company investigated supplying ENR headsets in a high noise area, but decided not to, since there was no demonstrated value. In short, ENR only works on lower frequencies, and those frequencies typically don't affect hearing as much as higher frequencies. ANR can be designed to work on any frequency. I suggest your company might want to check out the Bose ANR headphones (nonaviation). They seem to block out all frequencies. Great hearing protectors in a noisy environment.

The groom just asked the band to play "Your cheatin' heart", and the bride just requested "Don't come home a'drinkin' with lovin' on your mind".
