Noise induced hearing loss is all about the 'dose' of noise. The period
of exposure is relevant as well as the sound pressure level. The
frequency of the noise is also important - although a simple db(A) level
is usually enough to indicate a potential problem.

An interesting snippet here:
http://www.jehr-online.org/volume2/issue1/6/index.asp

I once helped a student do some tests on hand-arm vibration level
exposure from motorcycle handlebars. They were a bit rough and ready
without exactly the right equipment, but they confirmed why my poor old
digits tingle after a good thrash on the Morini,

Those old police A65s must have been perilously close to giving
patrolmen 'white finger'.

De Reynaud's Syndrome (spelling? have I got the name right?) is a nasty
thing here. A friend suffers from it. The combination of cold and even
minor vibration was enough to turn her fingers quite white.



Correct. It can be brought on by hand-arm vibration but can also be associated with arthritis type disease without exposure to vibration.

Being subject to a bit of incipient hip seizure, brought on in part I suspect by a hefty thwack falling off over the finish line of Hartland Quay hill climb many years ago, I reckon my hand problems are probably more down to arthritis. A daily dose of Glucosamine + Chondroitin keeps things moving fortunately - highly recommended! Had to get rid of the Saturno because I couldn't cope with the clip-ons and rear-sets any longer and thought carpal tunnel syndrome might be setting in.
