Wideband acoustic immittance measurement apparatus for human ear resonance
A recently granted patent (Publication Number: US11992309B2) discloses a wideband acoustic immittance measurement apparatus designed for determining wideband acoustic immittance in the human ear. The apparatus includes an ear probe with an acoustic output port emitting sound into the ear and an acoustic input port receiving sound, along with a loudspeaker and microphone for sound emission and detection. A processor is utilized to provide output audio signals, receive input audio signals, and determine wideband acoustic immittance as a function of frequency, identifying middle ear resonances based on the immittance data.
Furthermore, the patent details the identification of middle ear resonances based on determined wideband acoustic admittance at specific resonance frequencies, where conductance and gradient criteria are met. The processor is also capable of identifying multiple middle ear resonances and determining parameters of the wideband acoustic immittance at these resonances. Additionally, the apparatus includes features such as an air pump for applying static pressure to the ear canal, allowing for the determination of wideband acoustic immittance as a function of frequency and static pressure. The frequency range of the output audio signal is specified to span from 200 Hz to 3 kHz or 4 kHz, providing a comprehensive analysis of the ear's acoustic properties.
