The method is used for calculating the middle ear acoustic immittance bymeasuring electrical impedance of a receiver. The method comprises the following steps of applying pressure to the ear canal of a subject in a predetermined ear canal pressure range; sending a soundpressure signal with determined frequency range and amplitude to the ear canal of the subject through the receiver; based on a pre-built receiver detection circuit, measuring the input electrical impedance of the receiver; according to the input electrical impedance of the receiver, and based on a pre-established acoustic immittance calculation
