发明名称 Method for the recording of acoustic parameters for the customization of hearing aids
摘要 Acoustic parameters of an ear are recorded by measuring the impedance of the ear canal. A first pressure microphone measures the sonic pressure. A second pressure microphone measures the sonic pressure through a calibrated acoustic resistance. The sound energy flux is determined by the difference between the measured sonic pressures. The impedance is calculated from these results.
