Noise and vibration in Helicopters
Hi,
I'm currently flying the S-92. Vibration is - in my view - the biggest problem, because of the impact on the hearing.
As Health and Safety rep. for the Pilots at my base and AAP IFALPA rep for Norway (Norsk Flygerforbund - Norwegian ALPA) I'm about to give a speech on Noise and Vibration in Helicopters at the end of April to a Flight Safety Forum.
The current speed restriction from Sikorsky helps....
70% torque is good...
6 AVC's are better than 3....some times.
....but in the hangar - only AC - and the cockpit screen cooler fans running, 110 dB has been measured.....OUTSIDE the S-92!!
Hush kit is available (2-3 dB as I recall, correct me)
I'm very interested in :
- your type of hearing protection equipment flying the S-92 and other large helicopters
- your experience on the equipment (yearly flying hrs, torque setting,S-92..)
- do you have tendency to - or do you have tinnitus? Any corrolated hearingloss?
- links to scientific research (I do have the Norwegian ones and the one made in Southhampton back in 1988)
- your thoughts on how to solve the problems

If will - ofcourse - respect your privacy, and I do not need any personal information.
Just trying to get an overall picture, because everybody is talking about it, and not many are doing something about it.
Best regards
