It is important to select appropriate stimuli and test conditions for developing standardized spatial audiometric tests . In three experiments, binaural detection thresholds (BDTs) for a target signal, located at either 0, 45, 90, 135, 180, 225, 270, or 315° azimuth, were measured in the presence of a masker positioned at one of these eight locations . Target signals included spondaic words fro...

The staggered discontinuous Galerkin (SDG) method has been recently developed for the numerical approximation of partial differential equations. An important advantage of such methodology is that the numerical solution automatically satisfies some conservation properties which are also satisfied by the exact solution. In this paper, we will consider the numerical approximation of the inviscid B...

Introduction Auditory perception can be enhanced by musical training and practice. Considering the multiple brain areas involved in learning, good auditory perceptual skills contribute to phonological awareness, speech recognition presence of noise, reading, syllable recognition, other language skills. Material methods There were 30 adults between 18 27 years old who participated. They divided ...

UNLABELLED Phonological speech disorders are characterized by abnormal development towards the adult target pattern; its etiology is unknown. It is thought the this condition results from auditory processing disorders involving the abilities required for human beings to understand what is heard. AIM To investigate the relationship between auditory processing and the acquisition of disordered ...

Auditory evoked potentials (AEPs) and behavioral tests were used to evaluate auditory processing in 10 children aged 7 to 11 years who were diagnosed as learning disabled (LD). AEPs included auditory brainstem responses (ABRs), middle latency responses (MLRs), and late cortical responses (P1, N1, P2, P3). Late cortical responses were recorded using an active listening oddball procedure. Auditor...

Background: auditory processing (AP) and phonological awareness (PA) in children with and without phonological disorders. Aim: to compare the performance of children with and without phonological disorders in a PA test; to verify the possible relationship between performances in distinct tasks of this test with the performance in the AP evaluation. Method: participants were 44 children with and...

OBJECTIVE To verify the auditory selective attention in children with stroke. METHODS Dichotic tests of binaural separation (non-verbal and consonant-vowel) and binaural integration - digits and Staggered Spondaic Words Test (SSW) - were applied in 13 children (7 boys), from 7 to 16 years, with unilateral stroke confirmed by neurological examination and neuroimaging. RESULTS The attention p...

One protocol developed for the Tonal and Speech Materials for Auditory Perceptual Assessment audio compact disc was the masking-level difference (MLD) for spondaic words in which the words and broadband noise were mixed and recorded at 16 selected signal-to-noise ratios. Four words were recorded at each level. Because it was impossible to monitor the word presentations at negative signal-to-noi...

Thirty-six blast-exposed patients and twenty-nine non-blast-exposed control subjects were tested on a battery of behavioral and electrophysiological tests that have been shown to be sensitive to central auditory processing deficits. Abnormal performance among the blast-exposed patients was assessed with reference to normative values established as the mean performance on each test by the contro...
