Aplicação do teste de lateralização sonora em idosos

Abstract: Background: the ability to determine the direction of a sound source is based on the fact that sounds reach both ears at different times, phase, intensity and/or frequency. The perception of a sound source favors speech intelligibility in noisy environments. Aim: to identify the minimum time of interaural delay -produces lateralization to the ear which the stimulus reached first -through ascendant and descendent techniques, using the Sound Lateralization Test in elderly individuals with normal hearing threshol… Show more

“…This alteration can be associated with aging, for proper physiological modifications derived from pathological processes responsible for the clinical presentation of several of diseases occur in this life stage (13), a noticeable of which is presbycusis. The degenerating effects of aging can involve both the inner ear and CNS (14). Besides presbycusis, a HP alteration can also occur as a result of the metabolic changes and, regarding the age factor, those directly affecting the cerebral mechanism (15).…”

“…A presença de alteração no teste de escuta dicótica pode estar relacionada com a perda auditiva periférica ou com a própria idade, pois segundo autores 4,5,7 os efeitos do envelhecimento podem envolver tanto a parte periférica quanto central da audição e, quando o fator idade está relacionado diretamente com a perda auditiva periférica, esta pode estar dificultando ainda mais a escuta dicótica nos idosos. 9,10 Comparando os resultados desta pesquisa com os dados do grupo referenciado pelo padrão do autor 21 foi possível observar que; a DC apresentou diferença embora não significativa e semelhança no valor da EC.…”

“…6 Os efeitos degenerativos do envelhecimento podem envolver tanto a orelha interna quanto o sistema nervoso central (SNC). 4 Além da presbiacusia, alterações do processamento auditivo (PA) também podem acontecer, devido às mudanças metabólicas, e ao fator idade, que afetam diretamente o mecanismo cerebral. 5 O PA é a habilidade que os indivíduos possuem para utilizar os estímulos sonoros que escutam, portanto, é necessário que o sinal acústico seja analisado e interpretado para que se transforme em uma mensagem com significado.…”

“…In a research with elderly individuals, with normal hearing thresholds in the frequencies which are most import for speech recognition, Fonseca & Iório (2006) aimed to identify the minimum time of interaural delay -produces lateralization to the ear which the stimulus reached first -through ascendant and descendent techniques. The results bring sophisticated information about the hearing process of elderly individuals.…”
