ABSTRACT
Objective To keep the intensity of sound constant and reduce the effect of ear canal difference on detection process.Methods Real-time detection of the probe tone in ear canal was carried out and by control ling the output circuit of the probe tone through the digital signal compensation algorithm,to realize real-time digital tympanometry of ear system and the function of constant pressure control.Results The results showed that the probe tone remained constant at 226 Hz for the measurement of middle ear and tympanometry was accurate.Conclusion The study simplified system configuration and provides basis for the clinical application.
