I saw an ad on television once for a large newspaper chain and their slogan was; Never Stop Thinking. Audiometrically, there is no difference between her data and those seen in fifth case above. It is possible that one may hear sounds such as your own pulse or the contractions of your muscles which is referred to as pulsatile sonus complete. This causes thickening of mucous of the inner ear, so that the mucous cannot drain from the Eustachian tubes.
