With developments in software and micro-measurement technology, a three-dimensional
middle ear finite element (FE) model can now be more easily constructed to study sound …

In an earlier article in this supplement, Rosowski et al.(pp. 9S–16S) define acoustic
immittance, reflectance, absorbance, and power reflectance (PR), and describe their …

Background: Although tympanic membrane perforations are common, there have been few
systematic studies of the structural features determining the magnitude of the resulting …

The purpose of this study was to examine wideband energy reflectance (ER) at ambient
pressure in adults with a variety of middle-ear disorders. The ER results from 9 participants …

A three-dimensional (3D) finite element (FE) model of human ear with accurate structural
geometry of the external ear canal, tympanic membrane (TM), ossicles, middle ear …

The test performance of a wideband acoustic transfer function (ATF) test and 226-Hz
tympanometry was assessed in predicting the presence of conductive hearing loss, based …

A system with potential for middle-ear screening and diagnostic testing was developed for
the measurement of wideband energy absorbance (EA) in the ear canal as a function of air …

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 …

Measurements of middle ear (ME) acoustic power flow (power reflectance, power
absorption, and transmittance) and normalized impedance (acoustic resistance, acoustic …

Objective: This study tested the hypothesis that wideband aural absorbance predicts
conductive hearing loss (CHL) in children medically classified as having otitis media with …
