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.
