Assessment of Conductive Dysfunction: Wideband Acoustic Immittance
The conductive mechanism plays an important role in our hearing: the first stage of signal processing in the auditory system. While it consists of the ear canal, the crucial portion is the middle ear system, which transforms airborne sound into mechanical vibration and helps improve sound transmission into the fluid-filled inner ear. Hearing loss due to dysfunction of the middle ear system may ...
متن کاملWideband acoustic immittance: Concepts and clinical utility
Measurements of middle ear (ME) acoustic power flow and related measures (e.g., reflectance, absorbance, impedance, resistance, and reactance) have several important advantages over other measures of acoustic impedance, such as the clinical “gold standard” measure, tympanometry. In addition to its wide bandwidth and ease of use, the absorbance curve, on a dB scale, has a shape that is similar t...
متن کاملWideband acoustic immittance for assessing middle ear functioning for preterm neonates in the neonatal intensive care unit
BACKGROUND The primary aim of newborn hearing screening is to detect permanent hearing loss. Because otoacoustic emissions (OAEs) and automated auditory brainstem response (AABR) are sensitive to hearing loss, they are often used as screening tools. On the other hand, false-positive results are most often because of transient outer- and middle ear conditions. Wideband acoustic immittance (WAI),...
متن کاملSelf-crimping superelastic nitinol prosthesis and malleostapedotomy: a temporal bone study.
OBJECTIVE The aim of this study was to compare the results of application of 2 types of superelastic nitinol prostheses. STUDY DESIGN Temporal bones study with planned data collection. SETTING Tertiary referral center. SUBJECTS AND METHODS Malleostapedotomy was performed in 15 human temporal bones implanting 3 different prostheses: manually crimping polytetrafluoroethylene (MC-PTFE) pisto...
متن کاملEffects of Negative Middle Ear Pressure on Wideband Acoustic Immittance in Normal-Hearing Adults.
OBJECTIVES Wideband acoustic immittance (WAI) measurements are capable of quantifying middle ear performance over a wide range of frequencies relevant to human hearing. Static pressure in the middle ear cavity affects sound transmission to the cochlea, but few datasets exist to quantify the relationship between middle ear transmission and the static pressure. In this study, WAI measurements of ...
