Processamento auditivo, resolução temporal e teste de detecção de gap: revisão da literatura

Abstract

TEMA: processamento auditivo temporal e resolução temporal. OBJETIVO: realizar revisão teórica sobre processamento auditivo e resolução temporal, bem como sobre os diferentes parâmetros de marcadores utilizados em testes de detecção de gap e como eles podem interferir na determinação dos limiares. CONCLUSÃO: o processamento auditivo e a resolução temporal são fundamentais para o desenvolvimento da linguagem. Em virtude dos diferentes parâmetros que podem ser utilizados no teste em questão, os limiares de detecção de gap podem variar consideravelmente.

Temporal resolution with click and pure tone stimuli in youngsters with normal hearing sensitivity

“…The data revealed that subjects presented a very similar performance for both types stimuli used in the RGDT test: the click and the pure tone. When comparing the RGDT test results obtained for the pure tone and click stimuli in this study to those in the reviewed literature, it was observed that the mean final temporal acuity threshold and the clicks in this study highly resemble those described by many other authors (5,(10)(11)(12)(13)(14) when a normal hearing population was studied. The mean final temporal acuity thresholds obtained at other studies in the literature with a population of similar age range to the one in the present study is between 4.77 ms and 12.2 ms (11,(13)(14)(15)(16)(17) .…”

“…Temporal processing, or the temporal aspects of hearing, may be defined as the perception of sounds and their modification in a determined time interval (4,5) . The categories of temporal processing are: the abilities of temporal ordering or sequencing, temporal resolution or discrimination, temporal integration and temporal masking (4,6) .…”

“…The focus of this research was temporal resolution, that can be defined as the ability to detect intervals of silence in the middle of sound stimuli or the shortest duration of silence that a subject may discriminate between two audible signals (4,5) .…”

“…Temporal resolution is fundamental for speech comprehension, as well as for reading because there are intervals of silence in different places in continuous speech (5,7,8) . A specific difficulty of the ability of temporal resolution reveals an injury of the physiological auditory mechanism of temporal processing, and the impairments of temporal processing may be related to phonological processing, deficits in auditory discrimination, receptive language and in reading (3,6) .…”
