Spatial release from masking (SRM) occurs when spatial separation between a signal and masker decreases masked thresholds. The mechanically-coupled ears of Ormia ochracea are specialized for hyperacute directional hearing, but the possible role of SRM, or whether such specializations exhibit limitations for sound source segregation, is unknown. We recorded phonotaxis to a cricket song masked by...

BACKGROUND Auditory processing and auditory sensibility to high Frequency sounds. AIM To characterize the localization processes, temporal ordering, hearing patterns and detection of high frequency sounds, looking for possible relations between these factors. METHOD 32 hearing fourth grade students, born in city of São Paulo, were submitted to: a simplified evaluation of the auditory proces...

The anatomy and function of the peripheral auditory system differs from person to person (sometimes to a clinical degree), but such differences are probably not correlated with linguistic knowledge. For example, the distribution of French speakers’ peripheral auditory sensitivities are probably no different from the distribution of auditory sensitivities of speakers of any other language. That ...

INTRODUCTION Tinnitus is a perception of sound without external source. For complete assessment of tinnitus, central auditory processing abilities should be considered in addition to the routine psychological evaluation of tinnitus characteristics. Temporal processing is one of the important auditory skills that are necessary for complex higher level auditory processing. MATERIALS AND METHODS...

OBJECTIVE To compare hearing performance relating to the peripheral and central auditory system between solvent-exposed and non-exposed workers. METHODS Forty-eight workers exposed to a mixture of solvents and 48 non-exposed control subjects of matched age, gender and educational level were selected to participate in the study. The evaluation procedures included: pure-tone audiometry (500 - 8...

The purpose of the study was to assess the prevalence of auditory and vestibular symptoms in workers exposed to occupational noise. There were examined medical records of 175 workers with noise-induced hearing loss who attended an occupational health reference center in the city Campinas, Southeastern Brazil, from 1997 to 2003. The variables studied were frequency of symptoms of hypoacusis, tin...

Establishing neural determinants of psychophysical performance requires both behavioral and neurophysiological metrics amenable to correlative analyses. It is often assumed that organisms use neural information optimally, such that any information available in a neural code that could improve behavioral performance is used. Studies have shown that detection of amplitude-modulated (AM) auditory ...
