Well, I had a hearing test about two years ago and was told I have a huge, huge, hole in the octave around 2k...I don't notice it except sometimes life just sounds like I am in a tunnel, but I suspect my brain compensates most of the time. My top end is fine. But they said the loss was likely from being around loud noise...I was a DJ for years wearing headphones, and then had a recording studio, on top of playing in bands, and am now paying for it. I really am more concerned about not standing a foot away from my (very loud) RCM for even a minute or less. So I'm happy that the steam seems to work well without the RCM, and records even seem to sound better to me without the vacuum. Of course, from a man admitting hearing loss, but I do think I'm not missing anything.
Oh, and I'm 37 - take care of your hearing!!!
