Article Abstract
Spontaneous otoacoustic emissions (SOAEs) and stimulus frequency otoacoustic emissions (SFOAEs) have been described from lizard ears. Although there are several models for these systems, none has modeled the characteristics of both of these types of otoacoustic emissions based upon their being derived from hair cells as active oscillators. Data from the ears of two lizard species, one lacking a tectorial membrane and one with a chain of tectorial sallets, as described by Bergevin et al. ["Coupled, active oscillators and lizard otoacoustic emissions," AIP Conf. Proc. 1403, 453 (2008)], are modeled as an array of coupled self-sustained oscillators. The model, originally developed by Vilfan and Duke ["Frequency clustering in spontaneous otoacoustic emissions from a lizard's ear," Biophys. J. 95, 4622-4630 (2008)], well describes both the amplitude and phase characteristics of SFOAEs and the relation between SFOAEs and SOAEs.
Background: The purpose of the research was to examine the prevalence rates of screening for genetics and hearing simultaneously in neonates and provide scientific evidence for the beneficial application of newborn screening in the Southeast China population.
Methods: Between June 2015 and March 2023, 27,843 newborns were enrolled in the study. All participants were screened by otoacoustic emissions at 2 days of age.
Objective: The objectives of the study were to (i) evaluate the effectiveness of wideband absorbance (WBA) at ambient pressure (WBA), tympanic peak pressure (WBA), and 0 daPa (WBA) to identify conductive hearing loss (CHL) in infants and (ii) compare the sensitivity and specificity of the three WBA tests with that of high-frequency tympanometry (HFT) and transient-evoked otoacoustic emissions (TEOAE).
Method: A total of 31 ears with hearing thresholds no greater than 20 dB HL (reference group from 20 infants [mean age: 3.1 weeks]) and 47 ears with CHL from 31 infants (mean age: 3.
Background: Little is known about audiovestibular function in psoriasis, a chronic systemic inflammatory disease that affects 2% of the world's population.
Objectives: To investigate audiovestibular function in patients with psoriasis.
Methods: In this prospective case-control trial, we enrolled 33 patients with psoriasis and 30 healthy controls.
The Test of Basic Auditory Capabilities (TBAC) consists of 19 discrimination and identification tasks selected to study individual differences in audition. In one TBAC study, performance was measured for 340 normal-hearing subjects, but no investigation into possible sex differences was undertaken. That dataset now has been re-analyzed by sex.
Auditory neuropathy spectrum disorder (ANSD) is often missed by standard hearing tests, accounting for up to 10% of hearing impairments (HI) and commonly linked to variants in 23 genes. We assessed 122 children with HI, including 102 with sensorineural hearing loss (SNHL) and 20 with ANSD. SNHL patients were genotyped for common variants using qPCR, while ANSD patients underwent whole exome sequencing, with variants analyzed across 249 genes.
