The acoustic rearing environment can alter central auditory coding properties, yet altered neural coding is seldom linked with specific deficits to adult perceptual skills. To test whether developmental hearing loss resulted in comparable changes to perception and sensory coding, we examined behavioral and neural detection thresholds for sinusoidally amplitude modulated (sAM) stimuli. Behaviora...

BACKGROUND behavioral and electrophysiological evaluations contribute to the understanding of the hearing system and to the intervention process. AIM to investigate the occurrence of P300 in subjects with congenital severe to profound hearing loss, according to the variables of gender, age and hearing loss level. METHOD the design of this research is a descriptive transversal study. Twenty-...

The microwave auditory effect has been widely recognized as one of the most interesting and significant biological phenomena from exposure. hearing pulsed microwaves is a unique exception to sound waves encountered in human perception. pulses involves electromagnetic waves. This paper reviews research humans animals leading scientific documentations that absorption single pulse impinging on hea...

UNLABELLED The main issue regarding pediatric audiology diagnosis is determining procedures to configure reliable results which can be used to predict frequency-specific hearing thresholds. AIM To investigate the correlation between auditory steady-state response (ASSR) with other tests in children with sensorineural hearing loss. METHODS Prospective cross-sectional contemporary cohort stud...

ra (rheumatoid arthritis) is a chronic multisystem disease with a variety of systemic manifestations. one of these manifestations, is hearing disorder, so study of the relation between ra and hearing disorders is seem important. this was a case-control study which has done from december 2004 to august 2006. this study compared 50 patients with ra, with age, sex and job-matched as control. audio...

Objective: The estimation of perceptive thresholds is a basic element of psychoacoustics. One of the drawbacks of commonly used adaptive algorithms is the lack of reliability when the behavioral response is not robust. To address this issue an adaptive algorithm, TEMA (Threshold Estimation by Managed Algorithm), has been developed. Design: TEMA seeks the 50% point on the psychometric curve base...

BACKGROUND This study examined the relative contribution of genetic and environmental effects on the air-conducted hearing threshold level (0.5-4 kHz) and speech recognition threshold level of the better ear as well as self-reported hearing in older women. METHODS Hearing was measured as a part of the Finnish Twin Study on Aging in 103 monozygotic (MZ) and 114 dizygotic (DZ) female twin pairs...

Background: behavioral and electrophysiological evaluations contribute to the understanding of the hearing system and to the intervention process. Aim: to investigate the occurrence of P300 in subjects with congenital severe to profound hearing loss, according to the variables of gender, age and hearing loss level. Method: the design of this research is a descriptive transversal study. Twenty-n...

Background: Externalizing behavior in deaf children causes many psychological problems for their parents. Aggression and rule breaking behaviors in children with severe hearing loss may cause psychological problems in parents and in managing children's behavior. Consequently, the present study aimed at investigating the effect of parental behavioral training of mothers on reducing the externa...
