BACKGROUND To screen the newborn by Transient evoked Otoacoustic emission and to assess the incidence of hearing damage and associated risk factors. METHOD This longitudinal prospective observational study was conducted at a tertiary care hospital in India. A total of 415 babies were included in the study. All the newborns were evaluated with Transient evoked Otoacoustic emission (TEOAE) whic...

Introduction Deafness is one of the most important sensory disturbances at birth. Hearing loss can affect the development of speaking and learning during life. Early diagnosis and intervention improve language outcome. The  current study aimed to determine the frequency of profound congenital hearing loss in healthy newborn infants in Fars province. Methods In a multicenter prospective study, f...

Background: Congenital hearing loss delays many aspects of a child's development, including speech and socio-cognitive development. The aim of this study was determine the results of infant hearing screening with transient evoked otoacoustic emission (TEOAE) in Moradi Hospital, Rafsanjan, Iran: 2014. Materials and Methods: In this descriptive cross-sectional study from 6017 infants born in Nik...

To understand how the inner ear-generated sound, i.e., otoacoustic emission, exits the cochlea, we created a sound source electrically in the second turn and measured basilar membrane vibrations at two longitudinal locations in the first turn in living gerbil cochleae using a laser interferometer. For a given longitudinal location, electrically evoked basilar membrane vibrations showed the same...

This paper describes the implementation and performance of a nonlinear time-domain model of the cochlea for transient stimulation and human otoacoustic emission generation. The nonlinearity simulates compressive growth of measured basilar-membrane impulse responses. The model accounts for reflection and distortion-source otoacoustic emissions (OAEs) and simulates spontaneous OAEs through manipu...

Click-evoked otoacoustic emissions (CEOAEs) and acoustical responses evoked by bandlimited Gaussian noise (noise-evoked otoacoustic emissions; NEOAEs) were measured in three normal-hearing subjects. For the NEOAEs the first- and second-order Wiener kernel and polynomial correlation functions up to the sixth order were calculated by cross correlating the noise stimulus and the emission response....
