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 …

Objective: Reflectance measured in the ear canal offers a noninvasive method to monitor the
acoustic properties of the middle ear, and few systematic measurements exist on the effects …

Background: Wideband acoustic immittance (WAI) measurements are a relatively new class
of aural acoustic tests that have shown promise as useful tools for evaluating middle-ear …

Acoustic impedance/reflectance measurements were made at various ear-canal pressures
in 20 subjects with a clinical acoustic immittance instrument and an experimental …

Three methods for compensating multiple frequency acoustic admittance measurements for
ear canal volume were studied in 26 men with normal middle ear transmission systems …

Objective: The maturation of the external and middle ear in the human infant has significant
effects on the interpretation of measured ear-canal responses to acoustic stimuli. A tutorial …

This study established a normal middle ear resonance estimated from sweep frequency
tympanometry (250–2000 Hz) and established normal equivalent ear canal volume, static …

Objectives: The development of acoustic reflectance measurements may lead to
noninvasive tests that provide information currently unavailable from standard audiometric …

Background: Wideband acoustic immittance measurements of the middle ear, such as
wideband energy reflectance (ER), can provide information about how the middle ear …
