Desempenho de escolares de 7 a 12 anos no teste Gaps-in-Noise

OBJETIVO: Investigar o desempenho de escolares de 7 a 12 anos de idade, sem queixas auditivas, no teste Gaps-in-Noise (GIN). MÉTODOS: Todas as crianças foram submetidas à otoscopia, audiometria tonal, logoaudiometria, medidas de imitância acústica e teste dicótico de dígitos. Somente realizaram o teste GIN os escolares com resultados dentro do esperado nos referidos testes (37 crianças, sendo 20 de escola particular e 17 de escola pública). Uma vez que não houve diferença entre o desempenho das crianças de escola pública e escola particular, o grupo foi tratado como único. RESULTADOS: Foram encontrados os seguintes valores médios no GIN por faixa etária: 7 anos (5,65 ms); 8 anos (5,12 ms); 9 anos (4,87 ms); 10 anos (5,1 ms) e acima de 11 anos (4,75 ms). CONCLUSÃO: O limiar médio de detecção de gap na orelha direita foi de 5 ms e na orelha esquerda foi de 5,19 ms. Não houve diferença entre as diversas faixas-etárias, orelhas e gêneros, no que se refere aos limiares de detecção de gap avaliados pelo GIN.

Habilidades de resolução temporal em músicos violinistas e não músicos

INTRODUCTION: The temporal resolution is the perception of a time interval in which the individual discriminates two sounds being a skill involved in music. OBJECTIVE: To identify the performance of temporal resolution in musicians and no musicians violinists and correlate it with the average of the thresholds of low frequencies and acute as well as the time of exposure to music daily. METHOD: This study was characterized by be prospective and compared between two groups, one consisting of 20 violinists and other musicians for 20 semi no musicians matched for age and education were submitted to audiological evaluation and to the test Gaps In Noise (GIN) to evaluate the temporal resolution. RESULTS: The test performance of the GIN group of musicians was not significant in the control group is in the right ear (RE) or left (LE). The correlation between the average high frequencies for the LE with the GIN test was (p = 0.001) in the control group. The average frequencies for both ears in the group of musicians was statistically significant and the highest values for RE (p = 0.001). CONCLUSION: There was no difference between the performance of the GIN test for both groups as well as the correlation between duration of daily exposure to music and GIN. The audiometric threshold of high frequencies seemed to be relevant for testing GIN.

Teste GIN (Gaps-in-Noise) em ouvintes normais com e sem zumbido

the Gaps-in-Noise (GIN) test assesses the auditory temporal resolution skill. Studies have described the GIN test an instrument of easy application and with good sensitivity and specificity. to compare the results of the GIN test in normal listeners with and without tinnitus and to correlate the obtained results with pure tone thresholds and age. hearing tests were performed in 44 subjects (hearing threshold up to 25 dB HL in the frequencies of 0.25 to 8 kHz). Two groups were considered for comparison: the Control Group with 23 subjects, 8 men and 15 women, aged between 22-40 (mean 29.7), and the Research Group with 18 tinnitus patients, 3 men and 15 women, aged between 21-45 (mean 31.3). All subjects underwent pure tone audiometry, speech tests, acoustic immittance measurements and the GIN test. For the statistical analysis, the significance level of 0.05 was adopted. considering pure tone audiometry, the overall mean for hearing thresholds was significantly higher for the Research Group when compared to the Control Group (p = 0.001). The comparison between the groups for the performance in the GIN test indicated that the Control Group detected gaps with a shorter time interval than the Research Group (p < 0.001). There was no correlation between the age of the subjects and the level of the GIN test. the GIN test identified deficit in the hearing skill of temporal resolution in patients with tinnitus. In the studied age group (21 to 45 years) there was no correlation between age and the results obtained in the GIN test.

GIN (Gaps-In-Noise) Performance in the Pediatric Population

The recently developed Gaps-In-Noise (GIN) test has provided a new diagnostic tool for the detection of temporal resolution deficits. Previous reports indicate that the GIN is a relatively sensitive tool for the diagnosis of central auditory processing disorder ([C]APD) in adult populations. The purpose of the present study was to determine the feasibility of the GIN test in the pediatric population. This was a prospective pseudorandomized investigation. This investigation involved administration of the GIN to 72 participants divided into six groups of normal children ranging from 7 through 18 years of age. The approximate GIN threshold (the shortest gap duration for which at least four of six gaps were correctly identified) served as the dependent variable. Results were analyzed using an ANOVA to examine between- and within-group differences. No statistically significant differences were seen in GIN thresholds among age groups. In addition, within group analysis yielded no statistically significant differences between ears within each age group. No developmental effect was seen in GIN thresholds between the ages of 7 and 18 years. Children as young as age 7 are able to complete the GIN with no significant difficulty and perform at levels commensurate with normal adults. The absence of ear differences suggests that temporal resolution as measured by the GIN is an auditory process that develops relatively early and symmetrically (i.e., no laterality or ear dominance effects). The GIN procedure appears to be a feasible measure of temporal resolution in both pediatric and adult populations.

Speech Recognition and Temporal Processing in Middle-Aged Women

This study was designed to examine speech understanding ability and temporal processing in middle-aged women with normal or near-normal pure-tone thresholds. Speech understanding, temporal processing ability, and self-assessed hearing were measured in groups of younger and middle-aged females. Participants were younger and middle-aged females (n = 12 per group) with normal hearing through 4000 Hz bilaterally. Subjects were drawn from nonclinical populations. Speech understanding was measured in the presence of steady-state noise and competing speech, with and without perceived spatial separation of the target speech and masker. The Gaps-In-Noise (GIN) test (Musiek et al, 2005) was used to assess temporal resolution ability. In addition, subjects completed a questionnaire with several items from the Speech, Spatial, and Qualities of Hearing Scale (Gatehouse and Noble, 2004) to gauge their subjective ability to understand speech in complex listening situations. Data were analyzed via repeated-measures ANOVA and Pearson r correlations. Results showed that the performance of the middle-aged subjects was significantly poorer than that of the younger participants in the presence of a spatially coincident speech masker. Although performance in this listening condition was unrelated to pure-tone thresholds, it was strongly correlated with scores on the GIN test. Speech understanding performance in the presence of a steady-state masker was related to high-frequency pure-tone thresholds. These results suggest that some middle-aged women with little or no pure-tone hearing loss experience listening difficulty in complex environments. Results also suggest a strong relationship between temporal processing and speech understanding in certain competing speech situations.

The Effect of Presentation Level on the Gaps-In-Noise (GIN©) Test

The Gaps-In-Noise (GIN) test is a new procedure used in the diagnosis of central auditory processing disorders. Performance on the GIN is recorded as approximate gap detection threshold and percent correct. In order to utilize the GIN test clinically, it is important to know how presentation level influences performance on the GIN. To this end, ten normal-hearing adults were administered the GIN at 5, 10, 15, 20, 25, 30, 35, and 50 dB SL with regard to threshold to GIN noise. Results indicated that performance for both the approximate gap detection threshold (A.th) and percent correct improved with increasing presentation level. Performance at 35 dB SL was not significantly different from the standard clinical presentation level (50 dB SL). Gaps that were between 5 and 8 msec in duration tended to show more variation across presentation levels. Although an influence of presentation level was noted, this influence should not be manifested at the standard clinical presentation level.

GIN (Gaps-In-Noise) Test Performance in Subjects with Confirmed Central Auditory Nervous System Involvement

The purpose of the present study was to investigate the value of a new gap detection procedure called Gaps-In-Noise (GIN) for assessment of temporal resolution in a clinical population. The test consists of 0 to 3 silent intervals ranging from 2 to 20 msec embedded in 6-sec segments of white noise. The location, number, and duration of the gaps per noise segment vary throughout the test for a total of 60 gaps presented in each of four lists. The GIN procedure was administered to 50 normal-hearing listeners (group I) and 18 subjects with confirmed neurological involvement of the central auditory nervous system (group II). Results showed mean approximated gap detection thresholds of 4.8 msec for the left ear and 4.9 msec for the right ear for group I. In comparison, results for group II demonstrated a statistically significant increase in gap detection thresholds, with approximated thresholds of 7.8 msec and 8.5 msec being noted for the left and right ears, respectively. Significant mean differences were also observed in the overall performance scores (i.e., the identification of the presence of the gaps within the noise segments) of the two groups of subjects. Finally, psychometric functions, although similar for short and long duration gaps, were highly different for gaps in the 4- to 10-msec range for the two groups. A variety of psychoacoustic procedures are available to assess temporal resolution; however, the clinical use of these procedures is minimal at best. Results of the present study show that the GIN test holds promise as a clinically useful tool in the assessment of temporal resolution in the clinical arena.
