“…The results show a worse performance in all these tests among the elderly. There was a poorer performance in the left side hearing when compared to the right side for the same group, showing the effects of chronological age in dichotic hearing tests 4 . Quintero et al (2002) compared the performance of elderly individuals with normal hearing ones and those with symmetrical sensorineural hearing loss -characteristic of presbycusis, by means of disyllable recognition test in a dichotic task (SSW).…”

Speech understanding disorders in the elderly may be due to peripheral or central auditory dysfunctions. Asymmetry of results in dichotic testing increases with age, and may reflect on a lack of inter-hemisphere transmission and cognitive decline. Aim:To investigate auditory processing of aged people with no hearing complaints. Study design: clinical prospective.Materials and Methods: Twenty-two voluntary individuals, aged between 55 and 75 years, were evaluated. They reported no hearing complaints and had maximal auditory thresholds of 40 dB HL until 4 KHz, 80% of minimal speech recognition scores and peripheral symmetry between the ears. We used two kinds of tests: speech in noise and dichotic alternated dissyllables (SSW). Results were compared between males and females, right and left ears and between age groups.Results: There were no significant differences between genders, in both tests. Their Left ears showed worse results, in the competitive condition of SSW. Individuals aged 65 or older had poorer performances than those aged 55 to 64. Conclusion:Central auditory tests showed worse performance with aging. The employment of a dichotic test in the auditory evaluation setting in the elderly may help in the early identification of degenerative processes, which are common among these patients.

“…Similarly, frequency modulation detection was poorer in older than younger subjects and age-related differences were larger at 500 Hz than at 4000 Hz (He et al, 2007). Age-related changes in cognitive functioning, including selective attention, may also negatively affect performance on auditory processing tasks, such as frequency discrimination (Hallgren et al, 2001;Humes, 1996;Humes, 2005;Humes et al, 1991;Humes et al, 2005;Humes et al, 1996;Humes et al, 2006;Humes et al, 1994). Therefore, it is likely that age-related changes in the peripheral, central auditory and cognitive systems contribute to age-related declines in the ability to detect small changes in frequency.…”

“…Indeed, research has demonstrated that the DLT performance of elderly is decreased compared to younger participants (Alden, Harrison, Snyder, & Everhart, 1997;Bouma & Van der Endt, 1993;Gelfand, Hoffman, Waltzman, & Piper, 1980;Hallgren, Larsby, Lyxell, & Arlinger, 2001;Martin & Cranford, 1991;Strouse, Wilson, & Brush, 2000a). Also, an age-related increase of ear asymmetry has been reported: performance of the LE has been found to decrease stronger than performance of the RE (Jerger, Alford, Lew, Rivera, & Chmiel, 1995;Jerger, Chmiel, Allen, & Wilson, 1994;Strouse et al, 2000a;Strouse, Wilson, & Brush, 2000b).…”

However, this finding is still controversial since some aging studies have failed to find such an effect (Gelfand et al, 1980;Martini et al, 1988) or found that age effects could only be perceived in focussed attention conditions, in particular when attention had to be focussed at the LE (Alden et al, 1997;Bouma & Van der Endt, 1993;Hallgren et al, 2001). Findings of decreased LE performance in elderly suggest that aging differentially affects functional hemispheric asymmetry.…”

In the present study, dichotic listening performance of 31 older adults was compared with performance of 25 younger adults under free and focussed attention conditions. In addition to an age-related general decrease in performance, we observed in the focussed attention condition increased asymmetry in the elderly group: the decrease of recall performance was stronger for the left ear (LE) than for the right ear (RE), while the increase of localisation errors was greater for the RE than for the LE. Identifying and localising digits appear to be different processes mediated predominantly by the left and right hemisphere, respectively. Since agerelated reduced performance is strongest for the ear ipsilateral to the hemisphere dominant to that particular function, these findings may be ascribed to decline of corpus callosum functioning resulting in decreased interhemispheric interaction rather than to a selective decline of right hemisphere functions.Age-related decline in cognitive functioning in healthy older adults appears to be restricted to tasks that demand more effortful processing. On tasks demanding automatic processing, elderly adults perform similarly to younger adults. Agerelated decline most probably is a consequence of deficits in selective attention needed during effortful processing (Kinsbourne, 1980). In the present research, we studied age differences in dichotic listening performance. The dichotic listening test (DLT) is an excellent tool for examining age-related cognitive decline since it involves different degrees of attentional and memory processing.The DLT is a non-invasive procedure to study the lateralisation of cerebral functions. Kimura (1961) developed the standard DLT, in which pairs of spoken digits are presented through a headphone. In each trial, three digits are sequentially presented to the left ear (LE), while at the same time three other digits are sequentially presented to the right ear (RE). The participants are asked to report as many digits as possible after each trial. Kimura (1967) found that verbal stimuli presented to the RE are reported more accurately than verbal stimuli presented to the LE.According to the structural model proposed by Kimura (1967), this right-ear advantage (REA) is a consequence of the functional anatomical organisation of the central-auditory system and the cerebral representation of language functions.
