S.A.Naida A formula of normal human middle ear. Sound reflection form a tympanic membrane |
Acoustic bulletin, Vol. 5 ¹ 3, (2002) |
| A simple formula describing the process of the acoustic energy transmission in a normal human middle ear is obtained. Stated theory offers the challenge for early diagnostics of the ear diseases. On the base of the original technique of interpretation of tympanograms the preliminary verification of the obtained relations is made. It is shown that normal values of the power coefficients of reflection from the tympanic membrane and the sound transmission are close to 0.5. |
