The ratio of standard ear tympanogram and the area of the eardrum

The ratio of the tympanogram width (gradient) at a frequency of 226 Hz, which is standard for impedancemetry of the human middle ear, flexibility, the area of the eardrum and the angle that characterizes its obliquity, was theoretically and experimentally confirmed. It is determined that the magnitude of the outer ear canal volume coincides with an equivalent volume of the women's and children's middle ear at the resonance frequency.
