  • Systems and methods for middle ear immittance testing
    Patent number: 12016680
    Abstract: Acoustic immittance and other characteristics of ears may be determined by measuring eardrum displacements resulting from application of pressure to the eardrum. For example, optical coherence tomography may be applied to monitor eardrum displacements responsive to a sound. The pressure corresponding to the sound is measured by a suitable instrument such as a microphone. The measured displacements and pressures may be processed to obtain a measure of immitance.
    Type: Grant

    Date of Patent: June 25, 2024
    Assignee: AUDIOPTICS MEDICAL INCORPORATED
