Temporal Integration and Cochlear Bearing Loss
نویسنده
چکیده
The effect of off-frequency energy on temporal integration measurements was investigated. Temporal integration functions for unfiltered and high pass filtered sinusoids of 20 and 200 msec duration and 1 msec rise-fall times were obtained from 4 normal hearing subjects and 4 subjects with high frequency, cochlear hearing impairments. Independent OF filtering, normal hearing subjects produced integration functions that were similar to those shown by other research. All four hearing impaired subjects showed abnormal temporal integration in the unfiltered condition. When forced to listen on-frequency, two of the hearing impaired subjects demonstrated normal temporal integration. It was concluded that off-frequency energy can confound the measurement of temporal integration.

Diagnostic value of CT and MRI of Temporal Bone in Cochlear Implantation Candidates
Background Cochlear implantation is an approved treatment which can be used to treat severe to profound hearing loss. Imaging before cochlear implant surgery is very important in decision making and assessing the temporal bone anatomy for surgery. We aimed to assess the diagnostic value of high resolution CT scan (HRCT), and MRI of temporal bone in candidate pati...
متن کاملTemporal integration of loudness in listeners with hearing losses of primarily cochlear origin.
To investigate how hearing loss of primarily cochlear origin affects the loudness of brief tones, loudness matches between 5- and 200-ms tones were obtained as a function of level for 15 listeners with cochlear impairments and for seven age-matched controls. Three frequencies, usually 0.5, 1, and 4 kHz, were tested in each listener using a two-interval, two--alternative forced--choice (2I, 2AFC...
متن کاملCornelia De Lange Syndrome and Cochlear Implantation
Introduction: Literature regarding the different degrees of hearing loss in patients with Cornelia de Lange syndrome (CDLS) reports that half of the affected patients exhibit severe to profound sensorineural hearing loss. We present the first pre-school child with CDLS who underwent cochlear implantation for congenital profound sensorineural hearing loss. Case Report: A 3-year-old boy with CD...

Introduction: Cochlear implantation can facilitate the development of communication skills in children with profound hearing loss. The objectives of our study were to determine the average ages at suspicion and diagnosis of hearing loss, amplification, intervention, and performing the cochlear implantation and to investigate the effects of the parents’ level of education and economic circumsta...
متن کاملRole of audiovisual plasticity in speech recovery after adult cochlear implantation
The role of vision on the speech recovery after cochlear implantation is a subject of debate. In our study, we assessed the role of crossmodal reorganization and plasticity in auditory recovery in cochlear implanted deaf patients. Our results demonstrate that the initial functional level of the visual cortex leads to the greater proficiency in auditory recovery. Experienced patients had greater...
