I joined in 1993 and have flown helicopters since then until 6 years ago. My hearing started heading downhill in 2002 until now when I am MLD as a result, after a downgrade in 2016 FFS..... and H ‘very bad’ in each ear (high tone/speech range) diagnosed by RAF doctors and recorded as NIHL. I guess 3 years on Pumas and 15 years on Chinooks will do that (almost all Pre-CEPs). Funnily enough since I stopped flying and started staff work in earnest any further hearing loss has been considered age related.... think I have a case? Should I flag it now or wait for retirement aged 60, though? Also does anyone have a letter/note that was written years ago about the SH 4B4L helmet Pre CEPs and how bad they were at noise reduction?
