    The influence of cultural background on the soundscape experience in public spaces has been widely acknowledged. However, most studies have not used standardized protocols for soundscape perception data collection, nor have they gathered large datasets across different regions of the world to investigate possible cultural differences. This study explored the relationships between soundscape descriptors, perceived dominance of sound sources, and overall soundscape qualities and whether these relationships differ across world regions. A database of over 2000 soundscape surveys was collected in situ in outdoor public spaces in Europe and China. Results highlighted differences in how European and Chinese participants perceived the pleasantness and dominance of different sound sources. Specifically, the positive correlation between perceived pleasantness and natural sounds was stronger for European participants. For Chinese participants, vibrant soundscapes were positively correlated with perceived dominance of natural sounds, whereas in Europe, they were associated more with human-generated sounds. Perceived loudness had a greater effect on the appropriateness dimension for the Chinese sample than that for the European sample. This study provides a deeper understanding of how the geographical/cultural context can influence soundscape perception in public spaces and suggests that such country-specific factors should be considered when designing urban soundscapes

    Effects of Soundscape Complexity on Urban Noise Annoyance Ratings: A Large-Scale Online Listening Experiment

    Noise annoyance has been often reported as one of the main adverse effects of noise exposure on human health, and there is consensus that it relates to several factors going beyond the mere energy content of the signal. Research has historically focused on a limited set of sound sources (e.g., transport and industrial noise); only more recently is attention being given to more holistic aspects of urban acoustic environments and the role they play in the noise annoyance perceptual construct. This is the main approach promoted in soundscape studies, looking at both wanted and unwanted sounds. In this study, three specific aspects were investigated, namely: (1) the effect of different sound sources combinations, (2) the number of sound sources present in the soundscape, and (3) the presence of individual sound source, on noise annoyance perception. For this purpose, a large-scale online experiment was carried out with 1.2k+ participants, using 2.8k+ audio recordings of complex urban acoustic environments to investigate how they would influence the perceived noise annoyance. Results showed that: (1) the combinations of different sound sources were not important, compared, instead, to the number of sound sources identified in the soundscape recording (regardless of sound sources type); (2) the annoyance ratings expressed a minimum when any two clearly distinguishable sound sources were present in a given urban soundscape; and (3) the presence (either in isolation or combination) of traffic-related sound sources increases noise annoyance, while the presence (either in isolation or combination) of nature-related sound sources decreases noise annoyance

    Consensus Definition of Misophonia: A Delphi Study

    Get PDF
    Misophonia is a disorder of decreased tolerance to specific sounds or their associated stimuli that has been characterized using different language and methodologies. The absence of a common understanding or foundational definition of misophonia hinders progress in research to understand the disorder and develop effective treatments for individuals suffering from misophonia. From June 2020 through January 2021, the authors conducted a study to determine whether a committee of experts with diverse expertise related to misophonia could develop a consensus definition of misophonia. An expert committee used a modified Delphi method to evaluate candidate definitional statements that were identified through a systematic review of the published literature. Over four rounds of iterative voting, revision, and exclusion, the committee made decisions to include, exclude, or revise these statements in the definition based on the currently available scientific and clinical evidence. A definitional statement was included in the final definition only after reaching consensus at 80% or more of the committee agreeing with its premise and phrasing. The results of this rigorous consensus-building process were compiled into a final definition of misophonia that is presented here. This definition will serve as an important step to bring cohesion to the growing field of researchers and clinicians who seek to better understand and support individuals experiencing misophonia

    INTRODUCTION: A history of childhood trauma is an important determinant for understanding the development of psychiatric and physical disorders. The chronic inflammatory disease, psoriasis, has been reported to be affected by childhood psychological stressors. Early life stress is also a well-known contributor to major depression. The current study aims to clarify a possible association between levels and types of childhood trauma with psoriasis severity and major depression. METHOD: Sixty-four patients diagnosed with mild-to-severe psoriasis (male = 27, mean age = 52.51 ± 14.72 years and female = 37, mean age = 42.76 ± 14.45 years, age range = 21–77) were admitted to our study between April 2014 and September 2014. For the diagnosis of psoriasis, the single most recently developed lesion was examined dermoscopically and histopathologically. We evaluated the history of childhood trauma with the Childhood Trauma Questionnaire and diagnosis of major depression with the Mini International Neuropsychiatric Interview (MINI 5.0.0 current). The participants were scanned for their severity of psoriasis with Psoriasis Area and Severity Index 75 (PASI 75). Initially, the data were checked for normality using Kolmogorov–Smirnov/Shapiro–Wilk’s tests, histograms, and probability plots. Because normality of the data could not be assumed, we evaluated childhood trauma subscales and psoriasis by running Kendell’s tau-b correlation coefficients for bivariate comparisons. Mann–Whitney U test was conducted to assess the differences in childhood trauma severity of each subscale between two groups of depressed and non-depressed patients with psoriasis. Ultimately, we ran chi-square analysis to evaluate the association between gender and depression. RESULTS: Emotional (0.325), physical (0.614), sexual (0.963) abuse, and emotional (0.331) neglect were positively correlated with higher severity of psoriasis (p < .01). Subsequently, emotional (U = 372, p = .43), physical (U = 387, p = .049), sexual (U = 297, p = .0005) abuse, emotional (U = 299.5, p = .001), and physical U = 372, p = .031) neglect were significantly higher in psoriasis patients with depression compared to non-depressed (p < .05). CONCLUSION: The findings of the current study underline the relationship between childhood trauma and major depression, as well as childhood trauma and psoriasis. The increased level of emotional, physical, sexual abuse, and emotional neglect was linked to elevated severity of psoriasis. Likewise, all childhood trauma subtypes appeared to be more severe in the group of psoriasis patients with major depression. Investigation of childhood traumatic experiences, and major depression in individuals with psoriasis, the screening of depressed patients for psoriasis, and the cross-referencing of the outcome can be expected to provide remarkable findings, new approaches for diagnosis and treatment, as well as implications for promulgating new legislation

    The Psychophysiological Implications of Soundscape: A Systematic Review of Empirical Literature and a Research Agenda

    The soundscape is defined by the International Standard Organization (ISO) 12913-1 as the human&rsquo;s perception of the acoustic environment, in context, accompanying physiological and psychological responses. Previous research is synthesized with studies designed to investigate soundscape at the &lsquo;unconscious&rsquo; level in an effort to more specifically conceptualize biomarkers of the soundscape. This review aims firstly, to investigate the consistency of methodologies applied for the investigation of physiological aspects of soundscape; secondly, to underline the feasibility of physiological markers as biomarkers of soundscape; and finally, to explore the association between the physiological responses and the well-founded psychological components of the soundscape which are continually advancing. For this review, Web of Science, PubMed, Scopus, and PsycINFO were searched for peer-reviewed articles published in English with combinations of the keywords &lsquo;soundscape&rsquo;, &lsquo;environmental noise/sound&rsquo;, &lsquo;physiology/physiological&rsquo;, &lsquo;psychology/psychological&rsquo;, and &lsquo;perceptual attributes/affective/subjective assessment/appraisals&rsquo;. Previous research suggests that Electrocardiography (ECG) and Vectorcardiography (VCG) biometrics quantifying Heart Rate (HR), stimulus-locked experimental design, and passive listening with homogeneous populations are predominantly applied to characterize the psychophysiology underlying the soundscape. Pleasantness and arousal are the most frequent psychological descriptors for soundscape subjective appraisals. Likewise, acoustic environments are reported to inconsistently evoke physiological responses with great variability among studies. The link between the perceptual attributes and physiological responses of soundscape vary within and among existing literature. While a few studies detected a link between physiological manifestations of soundscape and the perceptual attributes, the others failed to validate this link. Additionally, the majority of the study findings were limited to one or two physiological responses

    This paper evaluates the proportion and the audiological and other characteristics of patients with symptoms of misophonia among a population seeking help for tinnitus and/or hyperacusis at an audiology clinic (n = 257). To assess such symptoms, patients were asked "over the last 2 weeks, how often have you been bothered by any of the following problems? Feeling angry or anxious when hearing certain sounds related to eating noises, lip-smacking, sniffling, breathing, clicking sounds, tapping?". The results of routine audiological tests and self-report questionnaires were gathered retrospectively from the records of the patients. Measures included: pure tone audiometry, uncomfortable loudness levels (ULLs), and responses to the tinnitus impact questionnaire (TIQ), the hyperacusis impact questionnaire (HIQ), and the screening for anxiety and depression in tinnitus (SAD-T) questionnaire. The mean age of the patients was 53 years (SD = 16) (age range 17 to 97 years). Fifty four percent were female. Twenty-three percent of patients were classified as having misophonia. The presence and frequency of reporting misophonia symptoms were not related to audiometric thresholds, except that a steeply sloping audiogram reduced the likelihood of frequent misophonia symptoms. Those with more frequent misophonia symptoms had lower values of ULLmin (the across-frequency average of ULLs for the ear with lower average ULLs) than those with less frequent or no reported symptoms. The reported frequency of experiencing misophonia symptoms increased with increasing impact of tinnitus (TIQ score ≥9), increasing impact of hyperacusis (HIQ score >11), and symptoms of anxiety and depression (SAD-T score ≥4). It is concluded that, when assessing individuals with tinnitus and hyperacusis, it is important to screen for misophonia, particularly when ULLmin is abnormally low or the TIQ, HIQ or SAD-T score is high. This will help clinicians to distinguish patients with misophonia, guiding the choice of therapeutic strategies

    Misophonia is characterised by a low tolerance for day-to-day sounds, causing intense negative affect. This study conducts an in-depth investigation of 35 misophonia triggers. A sample of 613 individuals who identify as experiencing misophonia and 202 individuals from the general population completed self-report measures. Using contemporary psychometric methods, we studied the triggers in terms of internal consistency, stability in time, precision, severity, discrimination ability, and information. Three dimensions of sensitivity were identified, namely, to eating sounds, to nose/throat sounds, and to general environmental sounds. The most informative and discriminative triggers belonged to the eating sounds. Participants identifying with having misophonia had also significantly increased odds to endorse eating sounds as auditory triggers than others. This study highlights the central role of eating sounds in this phenomenon and finds that different triggers are endorsed by those with more severe sound sensitivities than those with low sensitivity
