METHOD AND SYSTEM FOR RAPIDLY DETERMINING AND DISPLAYING THE DEPTH OF EAR TIP PLACEMENT TO IMPROVE THE RELIABILITY OF HEARING TESTS

摘要

Methods and systems for rapidly determining and displaying the depth of ear tip placement to improve the reliability of hearing tests may comprise in a hearing assessment system comprising a control system and a probe with a sealing ear tip, a microphone, and a sound source: measuring a pressure versus frequency of an ear canal, determining a first half-wavelength frequency of the ear canal using the measured pressure versus frequency and/or or from the phase of the ear canal reflectance, and calculating a distance between the hearing probe and an eardrum in the ear canal based on the determined first half-wavelength frequency. Subsequent measurements of the ear canal may be performed using the calculated distance. The calculated distance may be stored in a memory in the control system for the subsequent measurements of the ear canal. The calculated distance may be displayed on a gauge on the control system.
