“…In support of research studies examining the infl uence of background noise on CV processing (Martin et al, 1997;Shtyrov et al, 1998;Martin et al, 1999;Kozou et al, 2005;Martin & Stapells, 2005), the N1 and P2 activation in the anterior region appeared to be reduced and/or delayed Sequence and timing of a single trial. One trial contained three spoken words, prime (S1), target (S2), and probe (S3), separated by inter-stimulus intervals (ISI) as specifi ed.…”

“…The impact of noise on early cortical components such as the P1, N1, P2, MMN and P3a, primarily linked with pre-attentive stages (Martin et al, 1997;Shtyrov et al, 1998;Martin et al, 1999;Kozou et al, 2005;Martin & Stapells, 2005), has been well established while listening to speech syllables, and is generally characterized as reduced amplitudes and/ or delayed latencies at vertex electrode sites that are typical to early auditory perception.…”

“…Jaramillo et al (2001) found that speech stimuli were more efficiently processed than harmonical tones (non-speech stimuli) as reflected by an enhanced MMN and P3a ERP components. In agreement, Kozou et al (2005) found that speech and non-speech sounds of approximately equal complexity were processed differently in both silence, and noisy conditions. In silence, speech stimuli elicited an MMN response that had smaller amplitude and a longer duration than that elicited by equally complex non-speech stimuli.…”

“…The entire task consisted of a total of 1,000 auditory stimuli, with an interstimulus interval of 850 ms. Stimuli were delivered through two loudspeakers at a distance of 100 cm from the subjects, delivering approximately 75 dB SPL to both ears. Continuous white noise with a bandwidth from 125 to 8,000 Hz was added to the signal to create a signal-to-noise ratio of 10 dB [Kozou et al, 2005]. The two loudspeakers were positioned so that they were angled at 45° to the subjects' ears and at 90° to each other.…”

Mismatch negativity (MMN) has been widely used to study the function of central auditory processing in the elderly. However, current research has not yet considered the effect of noise and high-frequency hearing threshold on MMN in the elderly. The aim of this study was to evaluate the effect of aging and high-frequency hearing loss on speech-related MMN in noisy backgrounds. Additionally, the possible mechanisms of central auditory processing dysfunction in the elderly were investigated. Fifty people aged 61-80 (70 ± 5.8) years were recruited for this study. They were divided into a 61- to 70-year-old group and a 71- to 80-year-old group. Fifty younger adults aged 21-40 (31 ± 5.3) years were recruited as healthy controls. Pure-tone hearing thresholds were recorded. A speech discrimination score (SDS) and a speech-evoked MMN under white noise with a bandwidth from 125 to 8,000 Hz background condition were recorded. The relationships between SDS and MMN latency and amplitude were analyzed. The effects of age and binaural 2,000-, 4,000- and 8,000-Hz pure-tone hearing thresholds on MMN latency and amplitude were analyzed. We found that the hearing thresholds of 2,000, 4,000 and 8,000 Hz in the 61- to 70-year-old and 71- to 80-year-old groups were higher than those in the control group. The SDS in a noisy background in the 61- to 70-year-old and 71- to 80-year-old groups were lower than those in the control group. Speech-evoked MMN latency was longer in the 61- to 70-year-old and in the 71- to 80-year-old groups than in the control group (215.8 ± 14.2 ms). SDS and speech-evoked MMN latency were negatively correlated. Age and speech-evoked MMN latency were positively correlated, as were the binaural 4,000- to 8,000-Hz pure-tone hearing thresholds and speech-evoked MMN. This study suggests that in elderly subjects, the function of preattentive central auditory processing changes. Additionally, increasing age and high-frequency hearing thresholds create a synergy in neurons that is weakened in the MMN time window, which may be a cause of central auditory processing disorders in elderly subjects in noisy background conditions.
