“…Furthermore, changes in temporal and spectral signal features are other factors for an enhanced annoyance response found in laboratory and field studies [61][62][63]. These results are in compliance with neuro-biological and hearing research on the spectrotemporal filter mechanism of auditory attention [64][65][66][67]. If permanent changes of the temporal and frequency features occur the auditory system has difficulties to habituate and adapt-especially during nighttime.…”

Abstract:Background: A change to new tramways in Graz (Austria) led to severe complaints in residential areas. To understand the underlying reasons for these complaints, a systematic measurement campaign was designed. Methods: Six locations in Graz and two locations in a comparably sized city were selected. Parallel indoor recordings of sound and vibrations were conducted from 8:00 p.m. to 8:00 a.m. (due to sleep problems) at all locations. Results: Vibration levels remained below the limits of the Austrian standard (Wm-weighting) although variability was observed among sites, tram types and pass-bys. A complex characteristic of the acoustic feature space was found with A-weighting (differences between A-and C-weighting of more than 15 dB were observed). C-weighted background to peak noise ratios clearly distinguished "old" from "new" trams. Psychoacoustic indices indicated a high variability between locations and tram types. Roughness and loudness was higher in "new" versus "old" trams at most locations. "New" trams exhibited high sharpness values and variability, especially at higher speeds-when compared with trams from a control city. Conclusions: Standard indicators of sound and vibration were not sensitive enough to uncover the reasons for the complaints. Only the integrated analysis of the ambient soundscape (high signal-to-noise-ratio), the more noticeable sound (in psychoacoustic terms) and the observed high variance of the immissions provided guidance to implement appropriate technical solutions.

“…An alternative advantageous approach would be to use functional neuroimaging and electroencephalography (EEG) which would not only help to individualize psychometric diagnostics by integrating neurobiology and psychoacoustics, but will also allow us to study the specific neural activation patterns of NS reactions. Listening is not only possible through the auditory apparatus but is otoneurological and subjective as well (29).…”

“…Current research has focused on perceived acoustics such as loudness in order to understand the transformation of sensory coding of acoustic stimuli into perception of auditory events (29) and only preliminary attempts have been made to capture the neurodynamical and functional changes underlying NS. However, in doing so we would undoubtedly face the same variability in individual reactions to noise.…”

“…However, in doing so we would undoubtedly face the same variability in individual reactions to noise. Neuroimaging of perceived loudness, for example, is affected by personality and experiential factors which has led to the notion that capturing loudness perception "on an individual basis" might explain the variance in the data (29). Lee et al also found that, contrary to what might be expected, "the least annoying sound results in a lower alpha persistence compared to the most annoying sounds for the noise sensitive participants" (12).…”

“…duration, spectral content and temporal modulation as well many more acoustic and non-acoustic factors, including the particular task or context and personal factors like the individual hearing status (Florentine et al 2011). While the relationship between sound intensity and neural activity in the human central auditory pathway has been extensively studied by means of neuroimaging techniques, only a small number of studies have investigated the interrelation of sound intensity, loudness and the corresponding brain activity (for a review, see Uppenkamp and Röhl 2014). Some auditory functional magnetic resonance imaging (fMRI) studies suggest that neural activation, at least in auditory cortex (AC), might be more a representation of perceived loudness rather than of physical sound pressure level (Hall et al 2001;Langers et al 2007;Röhl and Uppenkamp 2012).…”

We report a systematic exploration of the interrelation of sound intensity, ear of entry, individual loudness judgments, and brain activity across hemispheres, using auditory functional magnetic resonance imaging (fMRI). The stimuli employed were 4 kHz-bandpass filtered noise stimuli, presented monaurally to each ear at levels from 37 to 97 dB SPL. One diotic condition and a silence condition were included as control conditions. Normal hearing listeners completed a categorical loudness scaling procedure with similar stimuli before auditory fMRI was performed. The relationship between brain activity, as inferred from blood oxygenation level dependent (BOLD) contrasts, and both sound intensity and loudness estimates were analyzed by means of linear mixed effects models for various anatomically defined regions of interest in the ascending auditory pathway and in the cortex. The results indicate distinct functional differences between midbrain and cortical areas as well as between specific regions within auditory cortex, suggesting a systematic hierarchy in terms of lateralization and the representation of sensory stimulation and perception.
