Noise levels and hearing protection

[Torque2]

Trying to assist in getting sensible ear protection for ground handling staff on the ramp. Does anyone have a link or information on general percieved noise levels on an airport ramp in particular with turbine/jet engines running ie maximum epdb/day etc? Thanks

Try the Cranfield Institute (I think that's the right name) they carry out research into aspects of aviation. Sorry I don't have a URL for them.
