Hmm, for NATS their stated limit is indeed 20dbhr loss, where as the CAA quote 35dbhr (bit of a difference).
My ear is no worse than -5dbhr on all frequencies except 500Hz (1000HZ and 2000Hz show no loss) where there is an apparent 30dbhr loss which is worrying. NATS medical bods this morning said its all on a case by case basis but I still feel sick. Off to do another audigram tomorrow to see what happens
