“…In the current study, the length of the stimulus was 150 msec-shorter than 200 msec , but longer than 40 msec used in Alain and McDonaldʼs (2007) study. The lack of age-related difference in ORN amplitude during passive listening is consistent with Alain et al (2012) and suggests that 150-msec sound duration is sufficient for older adults to process the mistuned harmonic. In older adults, the effect of musical training on the ORN amplitude was not significant, whereas the ORN was enhanced in younger musicians.…”

“…Although one study found a reduced ORN amplitude in older adults (Alain & McDonald, 2007), a more recent study found that this age-related difference was due to the length of the stimulus (Alain, McDonald, & Van Roon, 2012). When the harmonic complex was short (i.e., 40 msec), older adults were less likely to hear the mistuned harmonic as a separate sound object and this age-related decline coincided with a reduction in ORN amplitude recorded during passive listening (Alain & McDonald, 2007).…”

The ability to separate concurrent sounds based on periodicity cues is critical for parsing complex auditory scenes. This ability is enhanced in young adult musicians and reduced in older adults. Here, we investigated the impact of lifelong musicianship on concurrent sound segregation and perception using scalp-recorded ERPs. Older and younger musicians and nonmusicians were presented with periodic harmonic complexes where the second harmonic could be tuned or mistuned by 1-16% of its original value. The likelihood of perceiving two simultaneous sounds increased with mistuning, and musicians, both older and younger, were more likely to detect and report hearing two sounds when the second harmonic was mistuned at or above 2%. The perception of a mistuned harmonic as a separate sound was paralleled by an object-related negativity that was larger and earlier in younger musicians compared with the other three groups. When listeners made a judgment about the harmonic stimuli, the perception of the mistuned harmonic as a separate sound was paralleled by a positive wave at about 400 msec poststimulus (P400), which was enhanced in both older and younger musicians. These findings suggest attention-dependent processing of a mistuned harmonic is enhanced in older musicians and provides further evidence that age-related decline in hearing abilities are mitigated by musical training.

“…Age-related differences in these ERPs have been investigated in numerous experiments, which mostly showed that these ERPs were enhanced in older adults (or no significant differences were present). Age-related enhancements of P1 or its enhancements magnetic counterpart were found, for example, by Alain et al (2012), Bertoli et al (2005), Fabiani et al (2006), Kovacevic et al (2005), Pekkonen et al (1995), Pfefferbaum et al (1979), and Smith et al (1980). An N1 amplitude increase with growing age was found among others by Amenedo and a (1998), Anderer et al (1996Anderer et al ( , 1998, Ford and Pfefferbaum (1991), and Pfefferbaum et al (1984); but Goodin et al (1978) observed age-related reduction of the N1-P2 amplitude (measured from peak-to-peak).…”

This is the accepted version of Horváth, J., Gaál, Z. A., & Volosin, M. (2017). Sound offset-related brain potentials show retained sensory processing, but increased cognitive control activity in older adults. Neurobiology of Aging, 57,[232][233][234][235][236][237][238][239][240][241][242][243][244][245][246] AbstractIt has been hypothesized that age-related hearing loss is caused not only by peripheral, but also central changes in the auditory system. Many studies utilized event-related potentials (ERPs) elicited by sound onsets to characterize age-related differences in central auditory processing. Age-related ERP enhancements in such studies have often been interpreted in terms of elevated sensitivity to auditory stimulation. Such ERPs, however, comprise various components reflecting different aspects of auditory and task-related processing. The composition of the waveforms may considerably differ for ERPs elicited by other auditory events. In the present study ERPs elicited by tone-offsets were used to characterize processing differences between younger and older adults in a short-go, tone-duration discrimination paradigm. Whereas the onset-related auditory ERP was enhanced in the older adult group, no age-related differences were found in the offset-related auditory ERPs observable at temporal electrodes. In older adults, however, offset-related processing was dominated by an N2 that could reflect enhanced cognitive control activities. Because N2 was present regardless discrimination difficulty, younger adults may have framed the task as offset-detection, whereas older adults represented the task as "genuine" discrimination.

“…One note of caution is that it is difficult to strictly compare the two conditions in the present study because they differed not only in the presence or absence of delay but also in stimulus onset asynchrony and tone duration, as well as in the order number of the manipulated harmonic, all of which can affect the ORN response [15,23]. Yet the occurrence of similar responses despite these differences can also be regarded as a strength in that it supports the generalizability of the observed ORN response in newborns.…”

“…ORN and its magnetic equivalent are sensitive not only to mistuning [15,16,18,19,20,21,22,23] but also to other cues of concurrent segregation such as onset asynchrony [24,25], differences or discontinuities in location [5,26], dichotic pitch [17,27,28,29,30,31], and simulated echo [32,33]. …”

Newborn Infants Detect Cues of Concurrent Sound Segregation

Separating concurrent sounds is fundamental for a veridical perception of one's auditory surroundings. Sound components that are harmonically related and start at the same time are usually grouped into a common perceptual object, whereas components that are not in harmonic relation or have different onset times are more likely to be perceived in terms of separate objects. Here we tested whether neonates are able to pick up the cues supporting this sound organization principle. We presented newborn infants with a series of complex tones with their harmonics in tune (creating the percept of a unitary sound object) and with manipulated variants, which gave the impression of two concurrently active sound sources. The manipulated variant had either one mistuned partial (single-cue condition) or the onset of this mistuned partial was also delayed (double-cue condition). Tuned and manipulated sounds were presented in random order with equal probabilities. Recording the neonates' electroencephalographic responses allowed us to evaluate their processing of the sounds. Results show that, in both conditions, mistuned sounds elicited a negative displacement of the event-related potential (ERP) relative to tuned sounds from 360 to 400 ms after sound onset. The mistuning-related ERP component resembles the object-related negativity (ORN) component in adults, which is associated with concurrent sound segregation. Delayed onset additionally led to a negative displacement from 160 to 200 ms, which was probably more related to the physical parameters of the sounds than to their perceptual segregation. The elicitation of an ORN-like response in newborn infants suggests that neonates possess the basic capabilities of segregating concurrent sounds by detecting inharmonic relations between the co-occurring sounds.
