I’m deaf as a proverbial post. Ironically, the biggest contributing factor to my defective hearing was probably exposing my ears to loud after-market exhausts for long periods when I was younger. And wind noise.

I read an article which stated that the human ear should not be exposed for any length of time to a decibel level above that of the noise generated by the average hairdryer. A fairly accurate rule of thumb – do you need to raise your voice to be heard?

Sorry to put a “spanner in the works” but I wish I had protected my ears more when I was younger.
