Īge-related changes have been documented in the auditory periphery, the auditory portions of the central nervous system, and in many non-auditory portions of the cortex that are believed to mediate various cognitive functions. In cognitively intact elderly with presbycusis and poor speech discrimination, CAPD may be present in 5–10% of patients. Although prevalence data are not available, its prevalence appears to increase with age. While loss in peripheral hearing sensitivity explains many of the listening problems of elderly persons, age-related declines in general cognitive skill and central auditory processing also appear to contribute. Įlderly often have more difficulty understanding speech than younger adults, particularly in noisy and challenging listening situations. Moreover, it can be modified by top-down attentional control. The right-ear advantage (REA) in dichotic listening (DL) reflects stimulus-driven bottom-up asymmetry in speech processing. ĭichotic listening (DL) has been used to estimate the language lateralization and auditory attention both in children and in adults. There has been strong evidence of weaknesses in dichotic listening among children with a variety of learning, language, and reading problems, and evidence suggests an aging effect on the perception of dichotic stimuli. The ability to both integrate and segregate binaural information during normal listening is essential in accurate speech perception and localization, especially in difficult listening situations. Conclusionĭichotic listening ability was significantly affected in elderly patients.ĭichotic listening refers to listening to different acoustic events presented to each ear simultaneously. The elderly group scored significantly depressed scores of dichotic digits’ test, especially in the left ear than in the adult group. Both cases and control groups were subjected to otological examination, immittancemetry, puretone audiometry, speech audiometry, and central auditory processing assessment by the use of central questionnaire for elderly and dichotic digits (version II) test. Forty-five adult individuals (control group) with the age range 32–57 years, with no history of neurological disorders. Participant were 46 individuals within the age range of 60 to 89 years with no history of neurological disorder or cognitive impairment, and all the participants were of high social class. This was a case-control study conducted at the Audiology Unit, ENT Department. The aim of the present study was to explore the effects of aging on dichotic listening performance. This necessitates the need for central auditory evaluation in association of peripheral auditory evaluation. Elderly patients frequently suffer from problems in speech discrimination especially in noisy situation, and they also have several problems from using amplifications devices especially binaural amplification.
