We review recent progress in understanding the physical and physiological mechanisms
that generate otoacoustic emissions (OAEs). Until recently, the conceptual model underlying …

BACKGROUND It has long been recognized that unidentified hearing loss at birth can
adversely affect speech and language development as well as academic achievement and …

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 …

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 …

Objectives: To develop normative data for wideband middle-ear reflectance in a newborn
hearing-screening population and to compare test performance with 1-kHz tympanometry for …

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

Objective: Universal newborn hearing screening (UNHS) test outcomes can be influenced
by conditions affecting the sound conduction pathway, including ear canal and/or middle ear …

Previous studies have evaluated representation of the fundamental frequency (F 0) in the
frequency following response (FFR) of infants, but the development of other aspects of the …

Objectives: The purpose of this study was to evaluate the test performance of wideband
absorbance (WBA) in terms of its ability to predict the outer and middle ear status as …
