Comparison of acoustic immittance measures obtained with different commercial instruments.
Three acoustic admittance measurements (tympanometric peak pressure, peak compensated static acoustic admittance, and tympanometric width) were compared across seven commercially available acoustic immittance systems. Forty-nine adult subjects (45 females and 4 males), 16 to 50 years of age (mean = 27.7 years), with normal middle ear function participated in this investigation. Small but statis...
متن کاملAssessment 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 کاملAcoustic Immittance, Absorbance, and Reflectance in the Human Ear Canal.
Ear canal measurements of acoustic immittance (a term that groups impedance and its inverse, admittance) and the related quantities of acoustic reflectance and power absorbance have been used to assess auditory function and aid in the differential diagnosis of conductive hearing loss for over 50 years. The change in such quantities after stimulation of the acoustic reflex also has been used in ...
متن کاملDigital instrument for measurement of aural immittance: A preliminary report
Development of techniques for measurement of aural acoustic immittance (AAI) is reviewed . Measurement characteristics of selected AAI instruments are compared. Real-ear data obtained with a digital instrument are presented. Review of data support the suggestion that digital AAI instruments promote development of quantitative measurement protocols with greater efficiency and power.
