Purpose: Worldwide demand for accessible hearing health technology continues to increase
while the numbers of hearing healthcare specialists are grossly inadequate to meet this …

Objectives: The purpose of this study was to obtain behavioral hearing thresholds for
frequencies between 0.125 and 20 kHz from a large population between 10 and 65 yr old …

The reliability of nine measures of the stimulus level in the human ear canal was compared
by measuring the sensitivity of behavioral hearing thresholds to changes in the depth of …

Objective: This study compares measurements of ear-canal reflectance (ECR) to other
objective measurements of middle ear function including audiometry, umbo velocity (VU) …

Objective: The goal of the present study was to investigate the clinical utility of
measurements of ear-canal reflectance (ECR) in a population of patients with conductive …

Quantifying ear-canal sound level in forward pressure has been suggested as a more
accurate and practical alternative to sound pressure level (SPL) calibrations used in clinical …

This paper proposes an alternative approach to acoustic Thévenin calibration of an ear
probe. An existing methodology derives the Thévenin-equivalent source parameters from …

Sound pressure level in-situ measurements are sensitive to standing-wave pressure minima
and have the potential to result in over-amplification with risk to residual hearing in hearing …

The ear-canal acoustic impedance and reflectance are useful for assessing conductive
hearing disorders and calibrating stimulus levels in situ. However, such probe-based …

Measurements of the ear-canal reflectance using an ear probe require estimating the
characteristic impedance of the ear canal in situ. However, an oblique insertion of the ear …
