Conventionally the testing of hearing aid algorithm is accomplished by conducting listening test on hearing impaired, but these tests are not only time consuming but also causes exhaustion, especially in aged patients. Simulation based testing proves to be better option for preliminary evaluation of developed algorithm. A novel methodology based on wavelet transform is designed for dichotic pre...

In dichotic listening, a right ear advantage for linguistic tasks reflects left hemisphere specialization, and a left ear advantage for prosodic tasks reflects right hemisphere specialization. Three experiments used a response hand manipulation with a dichotic listening task to distinguish between direct access (relative specialization) and callosal relay (absolute specialization) explanations ...

Background: Chess is a game that involves many aspects of high level cognition such as memory, attention, focus and problem solving. Long term practice of chess can improve cognition performances and behavioral skills. Auditory memory, as a kind of memory, can be influenced by strengthening processes following long term chess playing like other behavioral skills because of common processing pat...

PURPOSE To compare the performances of children with dyslexia and a control group in behavioral tests of (Central) Auditory Processing and Long Latency Auditory Evoked Potentials (P300). METHODS Participants were 22 individuals with dyslexia (study group) and 16 individuals with typical development (control group). All individuals underwent behavioral and electrophysiological assessment of (C...

When two white noises differing only in phase in a particular frequency range are presented simultaneously each to one of our ears, a pitch sensation may be perceived inside the head. This phenomenon, called ’binaural pitch’ or ’dichotic pitch’, can be produced by frequency-dependent interaural phasedifference patterns. The evaluation of these interaural phase differences depends on the functio...

INTRODUCTION Hearing loss is one of the most common problems in elderly people. Functional side effects of hearing loss are various. Due to the fact that hearing loss is the common impairment in elderly people; the importance of its possible effects on auditory memory is undeniable. This study aims to focus on the hearing loss effects on auditory memory. MATERIALS AND METHODS Dichotic Auditor...

One test of dichotic listening utilizing nonverbal stimuli is included on the VA-CD Tonal and Speech Materials for Auditory Perceptual Assessment, Disc 1.0. It is a test using three tone complexes that meet the definition of musical chords. The dichotic chords were included as a complement to the three dichotic speech procedures on the VA disc because musical chords may depend on right hemisphe...

The role of attention in the differentiation of auditory processing disorders from attention deficit disorders is gaining considerable interest in both the clinical and research arenas. It has been well established that when attention is directed to one ear or the other on traditional dichotic tests, performance can be altered. However, preliminary studies in our laboratory have shown that dich...

INTRODUCTION AND OBJECTIVE Hearing disorders among school-age children are a current concern. Continuing studies have been performed in Poland since 2008, and on 2 December 2011 the EU Council adopted Conclusions on the Early Detection and Treatment of Communication Disorders in Children, Including the Use of e-Health Tools and innovative Solutions. The discussion now focuses not only on the ef...
