I sometimes work around 'loud' machinery. I am careful protecting my hearing so I use earmuffs with radio. Living in condos in past years I also use headphones quite a bit. Like my Sennheiser 380 pro that's quite worn out now. My listening habits do not include playing loud using headphones. I just don't like it.
For my age of just over half a century, I think my hearing is still fine albeit limited now to <14Khz.
Last June I got my first noise cancelling headphone Bose QC35 and I like it a lot. Wireless, the NC works amazingly well - even at work around loud machinery. It does even better job at cancelling out low freq sounds than my earmuffs of decent quality.
But here is the rub: Soon after I got the Bose I started to notice low amplitude high pitched noise in my ears after using them for few hours. Meaning, after I take them off, my ears are 'ringing' It sounds like I am listening to ~2khz noise at low volume. This isn't a serious problem and fades away rather quick and doesn't bother me really. But it's there! And I am limiting my use of them.
I was contemplating writing this post many weeks ago, but decided to wait and make sure there was a clear connection between this ear ringing and the Bose NC headphone. Since I am writing this I am fairly sure there is a connection.
My theory is this has something to do with the N.C. system.
Thoughts ?
