2007 US Contest Rules
The hearing loss is also attributed to tanks and helicopters. Years ago I
began having almost painful hearing at certain frequencies so I went and had my hearing checked. The doctor looked at my hearing graph and immediately guessed that I was either in tanks or helicopters. He was right, as I was a SAR swimmer for 3 years in the navy, and although I wore sound attenuators, when possible, the damage was still done. He said it was very easy syndrome to detect. So always wear headsets. Doug "Ian Strachan" wrote in message ups.com...

That is, other than hearing-loss ;-) True. Myself, I (almost) always wear a headset when running a Motor Glider engine in the air. In the UK Air Force there was a syndrome called "Shackleton Ear" which was permanent deafness on certain frequencies. The Shack had four Griffon piston engines (a sort of "double Merlin") and flew maritime patrol sorties many hours long. People who got "the ear" were generally those who took off their headsets for long periods of time. Ian Strachan Lasham Gliding Centre, UK |
