The bus is certainly queiter that the Boing(sp). But having done research of the subject trying to get ANR headsets supplied, it has been proven that it is not the ambient noise which causes hearing loss. It is the raised radio volume, to hear clearly over the ambient noise. Therfore, even with the bus noise levels, an ANR headset makes a huge difference. With my Sennheiser ANR headset, I have the RMP on min vol, as opposed to mid volume with company Sennheiser headsets. Much less tiring day!
It is funny tho when FO spots my radio turned down, and tries to be 'helpfull Harry' by turning it up for me.......
