Analyzing reverse middle-ear transmission: noninvasive Gedankenexperiments.
The phenomenological framework outlined in the companion paper [C. A. Shera and G. Zweig, J. Acoust. Soc. Am. 92, 1356-1370 (1992)] characterizes both forward and reverse transmission through the middle ear. This paper illustrates its use in the analysis of noninvasive measurements of middle-ear and cochlear mechanics. A cochlear scattering framework is developed for the analysis of combination...
متن کاملTitle : The Role of Resonance in Middle Ear Transmission
The rodent middle ear transmits sound pressure to the inner ear with high fidelity: in the frequency domain middle ear transmission is broad-band with a delay-like phase-frequency relationship, and in the time domain the time waveform is preserved. High fidelity transmission occurs despite the presence of pronounced mechanical resonances in the tympanic membrane (TM) and acoustic resonances in ...
متن کاملMiddle ear forward and reverse transmission in gerbil.
The middle ear transmits environmental sound to the inner ear. It also transmits acoustic energy sourced within the inner ear out to the ear canal, where it can be detected with a sensitive microphone as an otoacoustic emission. Otoacoustic emissions are an important noninvasive measure of the condition of sensory hair cells and to use them most effectively one must know how they are shaped by ...
متن کاملOssicular motion related to middle ear transmission delay in gerbil.
The middle ear transmits sound efficiently from the air in the ear canal (EC) to the fluid filled cochlea. In gerbil, middle ear transmission produces a constant pressure gain between the EC and the cochlea of ∼25 dB from 2 to 40 kHz, and a delay-like phase corresponding to a ∼25-30 μs delay. The mechanisms by which the air-born signal is collected and delivered to the cochlea are not thoroughl...
متن کاملDecrease in Middle Ear Resonance Frequency During Pregnancy
Many physiological changes occur during pregnancy. The aim of the study was to reveal whether there is a change in middle ear resonance frequency during pregnancy. A prospective case-control study was designed at a tertiary referral center. The study included 46 pregnant women at the third trimester (27-40 weeks) and 43 nonpregnant voluntary women. All the study subjects underwent pure-tone aud...
