NTRODUÇÃO: A presbiacúsia acarreta dificuldades na interpretação do sinal sonoro com uma influência acrescida na perceção do discurso na presença de ruído. Pretende-se estudar as habilidades do processamento auditivo cen-tral na discriminação da fala no ruído, em pessoas idosas.MATERIAL E MÉTODOS: A amostra foi constituída por 20 sujeitos, com idades compreendidas entre os 67 e os 92 anos. Todos realizaram otoscopia, timpanograma, audiograma tonal simples e teste de fala no ruído. Este estudo é do tipo descritivo-correlacional e transversal.RESULTADOS: A curva audiométrica apresenta declínio significativo (p < 0,001) com o aumento das frequências tes-tadas, a partir da frequência dos 500 Hz, apresentando o ouvido esquerdo melhores resultados do que o ouvido direito, com significância estatística (p = 0,043), apenas nos 250 Hz. No teste de fala no ruído, os resultados do ou-vido esquerdo evidenciaram uma média de acertos de 21,5% na relação sinal/ruído de 10 dB, tendo um aumento significativo (p < 0,001) na relação sinal/ruído de 15 dB cuja média de acertos foi 26,3%. O ouvido direito exibe uma média de acertos de 17,3% e de 27,85% na relação sinal/ruído de 10 dB e de 15 dB respetivamente, com um aumen-to significativo (p = 0,002) na relação sinal/ruído de 15 dB.CONCLUSÃO: Tendo em conta os resultados, em que o teste de fala no ruído apresenta uma média de acertos inferior aos 50% em ambos os ouvidos, chegámos à conclusão que quanto menor for a relação sinal/ruído maiores as dificul-dades na compreensão da fala. Assim, a avaliação audiológica da pessoa idosa deve incluir a avaliação periférica e central.

Background: Impairment in speech perception is a common feature of older adults. This study aimed at evaluating the acute and sub-acute (after three months) effects of auditory training on central auditory processing in older people with hearing loss. Methods: A nonrandomized study was conducted enrolling 15 older adults with hearing loss and an average age of 78.6 ± 10.9 years. All participants underwent a baseline otoscopy, tympanogram, audiogram and speech-in-noise test with a signal-noise ratio (SNR) of 10 and 15 dB. Afterwards, auditory training intervention was implemented consisting of 10 training sessions over 5 weeks. Participants were divided into two groups: group 1 (G1) underwent auditory training based on a speech-in-noise test; group 2 (G2) underwent a filtered-speech test. Auditory processing was evaluated at baseline (T0) immediately after the intervention (T1) and 3 months after the intervention (T2). Results: Group 1 were quite efficient regardless of the SNR in the right ear with statistically significant differences from T0 to T1 (p = 0.003 and p = 0.006 for 10 dB and 15 dB, respectively) and T0 to T2 (p = 0.011 and 0.015 for 10 dB and 15 dB, respectively). As for the left ear, the increase of success was statistically significant for the SNR of 10 dB and 15 dB from T0 to T1 (p = 0.001 and p = 0.014, respectively) and from T0 to T2 (p = 0.016 and p = 0.003). In G2, there was a significant variation only from T0 for T1 in the left ear for an SNR of 10 dB (p = 0.001). Conclusion: Speech perception in noise significantly improved after auditory training in old adults.

Background Postural instability is a possible symptom in children with otitis media, which often occurs in this population. The child with balance disorders usually has intolerance to sudden movements, difficulties in moving in the dark, nausea, vomiting and numerous fall events. To verify whether changes in the middle ear can influence the balance postural in children from 3 to 5 years. Methods The sample consisted of 31 children of both sexes, aged between 3 and 5 years. To collect data, a tympanogram was used to analyze the integrity of the tympanic membrane and the Modifid Clinical Test of Sensory Integration and Balance (MCTSIB), with four different sensory conditions, to assess static postural balance. Results Regarding the tympanogram, it was verified that the majority of the sample showed no changes, 45.2% of which were type A and 32.3% of type C1. Regarding the type B and C2 tympanogram, it was found that 12.9% of the sample had type B tympanogram and 9.7% type C2. When comparing these values with the MCTSIB results, there were no significant differences between the tympanogram with changes (B and C2) and the tympanogram without changes (A and C1), regarding the child's balance performance. Conclusions In this study, it was concluded that the alterations of the middle ear, proved through the tympanogram, did not influence the postural balance. However, it was found that the unilateral changes reported by the tympanogram, suggest higher values of postural oscillation, compared to bilateral changes.
