N Sky, thanks. Can you, or anyone else tell me which airlines recognise this problem, and what I really want is access to scientific report on this problem to wave at our tech pilot/health and safety rep. Any ideas?
Shame about H&S regs accepting the noise level, but this is a spurious argument on their part because it is not the anbient noise that is damaging, it is the nightclub-level of RT volume we need to overcome the ambient din without noise attenuating headset. And they measure ambient noise, not the din at ear level INSIDE the headsets, dont they?
