“…This explained why in some cases the ASSR thresholds were lower than those of behavioral hearing, especially at 1 and 2 kHz. These CFs are the least deviation between ASSR and behavioral hearing thresholds reported by many studies [9,13] .…”

Objective: It was the aim of this study to explore the use of auditory steady-state response (ASSR) to multiple simultaneous stimuli for threshold estimation in young children. Method: The subjects consisted of 40 children, aged from 6 months to 5 years, with variant degrees of sensorineural hearing loss. Simultaneous tonepips (0.5, 1, 2 and 4 kHz) with an amplitude modulated at different rates from 77 to 103 Hz were presented to both ears by insert phones. All children were tested with ASSR and age-appropriate behavioral tests. Results: We found that (1) ASSR thresholds were usually higher than behavioral thresholds with a difference of 8–15 dB, (2) the behavioral thresholds were significantly correlated with ASSR thresholds (p = 0.000), and (3) there was a great difference between ASSR thresholds and behavioral thresholds found in a child with auditory neuropathy. Conclusion: Being objective, frequency specific and well correlated with behavioral thresholds, ASSR to multiple simultaneous stimuli was proven to be a good tool to predict behavioral hearing thresholds.

“…Previously available evoked potential methods are too time consuming and the accuracy of the results greatly depends on the expertise of the evaluator [Stapells, 2000]. With the present technique we can minimize testing time without any appreciable loss of accuracy [John et al, 2001;Perez-Abalo et al, 2001]. Also, different statistical methods can be used to eliminate the bias introduced by human expertise in the interpretation of the results [Picton et al, 1987;Stapells et al, 1988;Dobie and Wilson, 1989;Valdes et al, 1997].…”

The Low and High Frequency Auditory Steady State Responses Mature at Different Rates

The age-related changes in the fast rate (70–110 Hz) auditory steady state response elicited by multiple-frequency tones (MSSR) that were amplitude-modulated (AM) are reported here. The MSSR was recorded in a sample of 64 well babies distributed into three age groups: 0–29 days (n = 25); 1–6 months (n = 26); 7–12 months (n = 13). Four simultaneously presented AM tones (0.5, 1, 2 and 4 kHz) were delivered monaurally through TDH 49 earphones, at different intensities (between 90 and 30 dB SPL). Clear developmental changes were found between birth and 12 months of age in response threshold, amplitude and detectability. Statistical analysis revealed that these changes occurred at different rates for low- and high- frequency responses. Nonetheless adult-like hearing thresholds were estimated reasonably well in most newborns and well babies, for all frequencies tested. Therefore the MSSR technique could be useful for objective frequency-specific audiometry beginning at birth.

“…That is, although neural-phase effects on behavioral performance have been demonstrated for a wide range of frequencies covering the classic delta (2, 4, 12, 28), theta (7,8), and alpha (7,10,14) bands, any single study has focused on only one frequency at a time. To be specific, although several studies have entrained neural oscillations at two or more different frequencies simultaneously (28,29) or entertained the possibility of phase effects in multiple frequency bands (7), no study of which we are aware has examined phase-phase effects on behavioral performance.…”

Our sensory environment is teeming with complex rhythmic structure, to which neural oscillations can become synchronized. Neural synchronization to environmental rhythms (entrainment) is hypothesized to shape human perception, as rhythmic structure acts to temporally organize cortical excitability. In the current human electroencephalography study, we investigated how behavior is influenced by neural oscillatory dynamics when the rhythmic fluctuations in the sensory environment take on a naturalistic degree of complexity. Listeners detected near-threshold gaps in auditory stimuli that were simultaneously modulated in frequency (frequency modulation, 3.1 Hz) and amplitude (amplitude modulation, 5.075 Hz); modulation rates and types were chosen to mimic the complex rhythmic structure of natural speech. Neural oscillations were entrained by both the frequency modulation and amplitude modulation in the stimulation. Critically, listeners' target-detection accuracy depended on the specific phase-phase relationship between entrained neural oscillations in both the 3.1-Hz and 5.075-Hz frequency bands, with the best performance occurring when the respective troughs in both neural oscillations coincided. Neural-phase effects were specific to the frequency bands entrained by the rhythmic stimulation. Moreover, the degree of behavioral comodulation by neural phase in both frequency bands exceeded the degree of behavioral modulation by either frequency band alone. Our results elucidate how fluctuating excitability, within and across multiple entrained frequency bands, shapes the effective neural processing of environmental stimuli. More generally, the frequency-specific nature of behavioral comodulation effects suggests that environmental rhythms act to reduce the complexity of highdimensional neural states.auditory perception | psychophysics | neuroscience L ow-frequency neural oscillations have recently been proposed to play a crucial role in perception (1-4). This is because lowfrequency neural oscillations reflect fluctuations in local neuronal excitability, meaning they influence the likelihood of neuronal firing in a periodic fashion (4-6). The result is that the probability that a (near-threshold) stimulus will elicit a neuronal response is not a uniform function of time but, instead, depends on the phase of the neural oscillation into which the stimulation falls. Indeed, the dependence of behavioral performance on neural oscillatory phase has been demonstrated in the visual (7-11) and auditory (12-15) domains.The role of neural oscillatory phase in perception is suggested to be of particular importance when stimuli possess temporal regularity (1,11,16,17). Precise alignment of neural oscillations with rhythmic stimuli is accomplished via entrainment, which is a process by which two oscillations become synchronized, or phaselocked, through phase and/or period adjustments (18). Through entrainment, perception of rhythmic stimuli is optimized when high-energy portions of a signal are aligned with periods of high excitab...
