Abstract
The frequency characteristics of sound transmission loss in the ear have been measured as a function of the static pressure difference across the tympanic membrane as well as the static pressure difference between the inner ear fluids and the middle ear. The measurements have been performed on cadaver ears from Norwegian cattle. On average, for an increasing static overpressure in the ear canal up to 10 cm of water in magnitude, the transmission loss below 1 kHz increases rapidly to about 13 dB for positive overpressures and to about 9 dB for negative, and then more slowly to about 28 and 26 dB at 60 cm of water. At higher frequencies the transmission losses become smaller, but are markedly different for positive and negative overpressures in the ear canal. The sound transmission in the ear is little influenced by a pressure increase in the inner ear fluids.
