Actually the notch is usually between 2.7-3K which is the resonant frequency of the outer ear/canal combination. When testing anyone who had a lot of noise exposure (often military) they had that notch as the low point of their response graph. At 4/6 and 8K the response was anywhere from 10-40db better.
