“…An important caveat, however, is that the model did not produce higher estimates of criterion SNR at threshold for younger listeners. Previous studies of children have argued that efficiency is poorer in younger listeners in a number of behavioral tasks, including those using psychophysical Grose, 1991a, 1994;Hartley and Moore, 2002;Hill et al, 2004) and speech stimuli (Stuart et al, 2006;Stuart, 2008). A failure to produce higher estimates of criterion for younger children in the present experiment could indicate a poor model fit.…”

Several lines of evidence indicate that auditory temporal resolution improves over childhood, whereas other data implicate the development of processing efficiency. The present study used the masking period pattern paradigm to examine the maturation of temporal processing in normalhearing children (4.8 to 10.7 yrs) compared to adults. Thresholds for a brief tone were measured at 6 temporal positions relative to the period of a 5-Hz quasi-square-wave masker envelope, with a 20-dB modulation depth, as well as in 2 steady maskers. The signal was a pure tone at either 1000 or 6500 Hz, and the masker was a band of noise, either spectrally wide or narrow (21.3 and 1.4 equivalent rectangular bandwidths, respectively). Masker modulation improved thresholds more for wide than narrow bandwidths, and adults tended to receive more benefit from modulation than young children. Fits to data for the wide maskers indicated a change in window symmetry with development, reflecting relatively greater backward masking for the youngest listeners. Data for children >6.5 yrs of age appeared more adult-like for the 6500-than the 1000-Hz signal. Differences in temporal window asymmetry with listener age cannot be entirely explained as a consequence of a higher criterion for detection in children, a form of inefficiency.

“…While masker modulation is often associated with improved speech perception in adults, the magnitude of this benefit differs widely across stimuli and conditions (e.g., Buss et al, 2009). Some data indicate a child/adult difference in the ability to benefit from masker modulation (Hall et al, 2012), although this is not always observed (Stuart et al, 2006;Stuart, 2008). It is therefore of interest to evaluate the benefit associated with masker modulation across listener age.…”

In adults, masked speech recognition improves with the provision of a closed set of response alternatives. The present study evaluated whether school-age children (5-13 years) benefit to the same extent as adults from a forced-choice context, and whether this effect depends on masker type. Experiment 1 compared masked speech reception thresholds for disyllabic words in either an openset or a four-alternative forced-choice (4AFC) task. Maskers were speech-shaped noise or twotalker speech. Experiment 2 compared masked speech reception thresholds for monosyllabic words in two 4AFC tasks, one in which the target and foils were phonetically similar and one in which they were dissimilar. Maskers were speech-shaped noise, amplitude-modulated noise, or two-talker speech. For both experiments, it was predicted that children would not benefit from the information provided by the 4AFC context to the same degree as adults, particularly when the masker was complex (two-talker) or when audible speech cues were temporally sparse (modulated-noise). Results indicate that young children do benefit from a 4AFC context to the same extent as adults in speechshaped noise and amplitude-modulated noise, but the benefit of context increases with listener age for the two-talker speech masker.

“…A literatura indica que o reconhecimento de fala das crianças normo-ouvintes é mais afetado por condições adversas como no ruído e/ou em ambiente reverberante quando comparadas aos adultos e esse desempenho pior em crianças para percepção da fala no ruído é esperado até os dez ou doze anos de idade (13)(14)(15)(16)(17)(18)(19)(20)(21). Os estudos supracitados não utilizaram ruído difuso, como as quatro caixas de campo livre adotadas no presente trabalho.…”

RESUMO Introdução:A habilidade em compreender a fala é afetada por muitos fatores durante as avaliações, principalmente no ruído, sendo ainda mais complexa para crianças nessas condições. Objetivo:Analisar a percepção da fala em crianças com audição normal em diferentes situações de ruído. Método:Forma 4CXS). Resultados:A análise estatística revelou diferença significativa entre as seguintes situações: RD com RF; RT com RF; sendo pior com 4CXS, onde foi encontrada diferença para RD, RT, RC, RE e RF. Para a análise de correlação com a idade, houve significância entre a idade em função dos valores HINT apenas para o ruído à frente. Conclusão:As diferenças significativas nos resultados de percepção da fala entre as diferentes condições de escuta no ruído na população estudada sugerem cautela na escolha do estímulo em avaliações de percepção da fala no ruído em crianças deficientes auditivas. Assim, pesquisas nessa linha são necessárias para estabelecer os parâmetros e variáveis relacionadas à sua aplicação e a interpretação dos resultados. Palavras-chave: audiologia, ruído, percepção da fala, testes de discriminação da fala. SUMMARY Introduction:The ability to understand a speech is affected for several factors during the evaluation mainly noise, and being more complex for children in these conditions. Objective:To analyse the speech perception in children with normal hearing in different situations of noise. Method:Study's way transversal cut. It was used the Brazilian Hearing in Noise Test(HINT) in 21 children with 7-14 years old with hearing inside the normality patterns and without cognitive alterations. Randomly was applied, sentence lists in the following situations: silent (S), noise in front (FN), noise at right (RN), noise at left (LN) noise at 180 o (TN) and compared the result of compound noise (CN) with diffuse noise from 4 sound fields in 45 o , 135 o , 225 o and 315 o (4CXS). Results:The statistics analyse showed the following situations: RH with FN; TN with FN; being worse with 4CXS, where was found difference for RN, TN, CN, LN and FN. To annalyse the age correlation, there was significance between age in HINT value functions just for noise in front. Conclusion:The significative differences in the speech perception results among the different conditions of hearing in noise in the studied population suggest caution in choosing the stimulus in speech perception evaluation in noise in auditive deficiency children. So, researches in this line are necessary to establish the parameters and variables related to their application and results interpretation.
