Sentence examples for middle ear response from inspiring English sources

Consequently, small nonlinear distortions may also be present in the middle ear response in the auditory frequency range.

We recorded the middle ear response to sound stimuli from 3 to 11 kHz at 80 dB SPL.

The weighting function W[kf] shown in Equation (8) represents the effect of the ear canal and the middle ear frequency response [24, 25].

We might, therefore, expect TGFβ pathway mutants to impact upon the middle ear's response to the hypoxia that develops in chronic OM.

In order to extract the perceptual components of the audio spectrum, a mapping reflecting the outer and middle ear frequency responses is applied on the spectral components, yielding the "Outer ear weighted DFT outputs" given as F e [ k f, n ] = F [ k f, n ] ⋅ 1 0 W [ k f ] 20.

Although up-regulated expression of S100A8 and S100A9 genes were observed in an animal model of otitis media (OM), their expressions have not been studied in human middle ear epithelial cells in response to the OM pathogen or in patients with recurrent or chronic OM (recurrent OM/RecOM or chronic OM with effusion/COME).

It has been approximately fifty years since Reysenbach de Haan [53] and Fraser and Purves [55] espoused that the evolutionary revamping of the middle ear was a corrective response to the selective pressures resulting from the large decrease in amplitude that occurred because of the transition between aerial and aquatic hearing environments.

The induction rate of mBD-2 expression in TLR2 KO mice middle ear epithelial cells in response to NTHi WCL was substantially lower than that of wild type mice (Fig 3B).

MacArthur and co-workers have published a study of middle and inner ear responses to trans-tympanic heat killed NTHi versus uninjected controls (GSE49122) [ 40].

The integrity of cochlear function in this population is provided by the presence of evoked oto-acoustic emissions and/or cochlear microphonics (CM), and the abnormal neural transmission or dys-synchrony is indicated by the absence of auditory brainstem responses and middle ear muscle reflexes.
