Building-up principles of auditory echoscope for diagnostics of human middle ear




middle ear, reflection coefficient, electroacoustic transducer, sound conducting tube


The building-up principles of diagnostic unit for determining the acoustic impedance with enhanced accuracy have been formulated using a case study of developing a laboratory prototype of auditory echoscope. This unit enables us to assess the condition of human middle ear both qualitatively and quantitatively and also determine the appropriate parameters by measuring the coefficient of acoustic reflection from tympanic membrane.
