“…Components are believed to be associated with sensory or cognitive information processing and are often measured by their amplitude and latency [26]. Latency is a time interval between stimulus onset and response [27] and amplitude is "The maximum extent of a vibration or oscillation, measured from the position of equilibrium" and is directly related to the intensity of a sound. [https://en.oxforddictionaries.com/definition/amplitude] Auditory perception as a reflection of sensory processing can be expressed by the ability to detect changes in different sound dimensions, such as frequency and intensity.…”

“…[https://en.oxforddictionaries.com/definition/amplitude] Auditory perception as a reflection of sensory processing can be expressed by the ability to detect changes in different sound dimensions, such as frequency and intensity. Natural sounds in the environment, such as speech and music, are complex acoustic signals that involve changes in intensity and frequency [27]. Therefore, abnormalities in amplitudes and latencies of ERPs in response to changes in frequency and intensity may contribute to the understanding of extreme behaviors related to sensory hypersensitivity in daily life [28].…”

Background: This study aimed to compare the neurophysiological responses to sound in adults with hypersensitivity compared to adults without hypersensitivity, and correlate the daily-life experiences to the neurophysiological manifestations. Material and Methods: The Adolescent/Adult Sensory Profile (AASP) was administered to 27 adults, separated by their cutoff scores. Differences in neurophysiological responses were measured by N 1-P 2 Event-Related Potentials (ERP) in response to auditory changes in frequency and intensity. Reactions to daily sounds were measured by the hyperacusis questionnaire. Correlations between AASP, hyperacusis questionnaire, and ERP were measured. Results: The basic ability to detect a change in stimuli manifested in N 1 waveform was not significantly different. However, participants with hypersensitivity presented a stronger P 2 response and a higher hyperacusis score. Daily expressions of auditory hypersensitivity correlated (p = 0.05-p = 0.01) with larger ERP responses. Conclusions: Auditory hypersensitivity as reflected in daily scenarios is evident in neurophysiological manifestations measured by ERPs. Understanding the relationship between the neural mechanisms of auditory hypersensitivity and its daily expressions, may optimize participation and wellbeing for people with hypersensitivity.

“…An abrupt change in a continuous sound evokes a clear cerebral response, peaking at approx. 100–180 ms following a change onset in sound frequency [1,2,3,4], sound intensity [1,5,6,7,8,9,10], sound location [1,11,12,13], or timbre [14].…”

“…Thus, the cerebral response seems to be a type of auditory change-related cerebral response (called “Change-N1”, and its magnetic counterpart “Change-N1m”). Change-N1 is also evoked by an abrupt decrease (dec-Change-N1) [8,9,16], as well as an abrupt increase (inc-Change-N1) in sound pressure.…”

Effects of Sound-Pressure Change on the 40 Hz Auditory Steady-State Response and Change-Related Cerebral Response

The auditory steady-state response (ASSR) elicited by a periodic sound stimulus is a neural oscillation recorded by magnetoencephalography (MEG), which is phase-locked to the repeated sound stimuli. This ASSR phase alternates after an abrupt change in the feature of a periodic sound stimulus and returns to its steady-state value. An abrupt change also elicits a MEG component peaking at approximately 100–180 ms (called “Change-N1m”). We investigated whether both the ASSR phase deviation and Change-N1m were affected by the magnitude of change in sound pressure. The ASSR and Change-N1m to 40 Hz click-trains (1000 ms duration, 70 dB), with and without an abrupt change (± 5, ± 10, or ± 15 dB) were recorded in ten healthy subjects. We used the source strength waveforms obtained by a two-dipole model for measurement of the ASSR phase deviation and Change-N1m values (peak amplitude and latency). As the magnitude of change increased, Change-N1m increased in amplitude and decreased in latency. Similarly, ASSR phase deviation depended on the magnitude of sound-pressure change. Thus, we suspect that both Change-N1m and the ASSR phase deviation reflect the sensitivity of the brain’s neural change-detection system.

“…Previous studies have mainly focused on temporal integration and thresholds in relation to duration and level. The effects of changes in sound level (Martin and Boothroyd, 2000;Dimitrijevic et al, 2009;Nishihara et al, 2011;He et al, 2012;Soeta and Nakagawa, 2012), frequency (Martin and Boothroyd, 2000;Dimitrijevic et al, 2008;Pratt et al, 2009;Yamashiro et al, 2011;He et al, 2012;Weise et al, 2012Weise et al, , 2018Vonck et al, 2019;Zhang et al, 2021), and location (Zhang et al, 2021;Fan et al, 2022) on brain responses have been investigated. A larger change caused larger N1 and P2 responses, which are typical responses of auditory evoked potentials (AEPs) and fields.…”

Air conditioners are typically installed in buildings and vehicles to control thermal conditions for long periods of time. Air conditioners generate certain types of sounds while functioning, which are among the main noise sources in buildings and vehicles. Most sounds produced by the air conditioner do not change with time, and the sound quality of steady sounds has been investigated. However, air conditioners can generate low-level impulsive sounds. Customers complain of the discomfort caused when these sounds disturb the silence in their living rooms and bedrooms. This study aimed to determine the physical factors that have a significant effect on physiological responses to low-level impulsive sounds produced by air conditioners. We used physiological responses because it is difficult for people to evaluate sounds psychologically when they are sleeping or are not focused on the sounds. The A-weighted equivalent continuous sound pressure level (LAeq) and the factors extracted from the autocorrelation function (ACF) were evaluated as physical factors. Participant responses on electroencephalography (EEG) were evaluated. The correlation between the EEG responses and ACF factors was determined. The LAeq, peak, and delay time to the first maximum peak of the ACF were identified as significant factors for physiological responses to low-level impulsive sounds.
