Associations between noise sensitivity and sleep, subjectively evaluated sleep quality, annoyance, and performance after exposure to nocturnal traffic noise
TL;DR: The results suggest that alterations of subjective evaluation of sleep were determined by physical parameters of the noise but modified by individual factors like noise sensitivity.
Abstract: In order to determine the influence of noise sensitivity on sleep, subjective sleep quality, annoyance, and performance after nocturnal exposure to traffic noise, 12 women and 12 men (age range, 19-28 years) were observed during four consecutive nights over a three weeks period. After a habituation night, the participants were exposed with weekly permuted changes to air, rail and road traffic noise. Of the four nights, one was a quiet night (32 dBA), while three were noisy nights with exposure to equivalent noise levels of 39, 44, and 50 dBA in a permuted order. The traffic noise caused alterations of most of the physiological parameters, subjective evaluation of sleep, annoyance, and performance. Correlations were found between noise sensitivity and subjective sleep quality in terms of worsened restoration, decreased calmness, difficulty to fall asleep, and body movements. The results suggest that alterations of subjective evaluation of sleep were determined by physical parameters of the noise but modified by individual factors like noise sensitivity.

TL;DR: In this paper, the effects of aircraft noise exposure on children's mental health problems such as depression and personality were investigated in the vicinity of Gunsan airport, and the results suggest that exposure to aircraft noise at school is associated with mental health issues in children.
Abstract: Objectives: This study was conducted to investigate the effects of aircraft noise exposure on children’s mental health problems such as depression and personality. Methods: We obtained data from the health examinations of school children in the vicinity of Gunsan airport. This survey was conducted in the rural area, Gunsan during 2009. The study population included 195 children attending 4th to 6th grade from 6 elementary schools near the airport. Based on 60 Weighted Equivalent Continuous Perceived Noise Level (WECPNL) measures of aircraft noise, participants were divided into 2 groups; the exposure group consisted of 106 children from 4 schools, and the reference group included 89 children from the 2 schools in Gunsan. All children completed questions on general characteristics, the Korean Children's Depression Inventory (KCDI) for depression, and the Korea Human Nature Inspection (KHNI) for personality. Results: Children in the exposure group were at higher risk of depression (5.62, 95% CI 1.12~28.25), and personality changes (2.08, 95% CI 1.07~4.05) than those of the reference group. In particular, children's diligence, cooperation, and concentration, subgroups of personality measure, were affected significantly and negatively, by aircraft noise level. Conclusions: Our results suggest that exposure to aircraft noise at school is associated with mental health problems in children. Requirements should be implemented to manage aircraft noise of its affect on children's health.

TL;DR: A systematic overview of the existing evidence investigating the health effects of environmental noise is provided in this article , where the authors show that the after-effects of noise-induced sleep disturbance are associated with numerous healthrelated problems including fatigue, reduced cognitive and physical performance, increased anxiety and negative emotional states such as anger and depression.
Abstract: This chapter provides a systematic overview of the existing evidence investigating the health effects of environmental noise. There is now considerable scientific literature linking environmental noise exposure with a wide array of negative health effects. The most significant of these are annoyance and sleep disturbance, and a range of cardiovascular outcomes such as hypertension and ischaemic heart disease. Other emerging effects include myocardial infarction (heart attack), stroke, adverse birth and fertility issues as well as tentative links with various cancers. Moreover, the after-effects of noise-induced sleep disturbance are associated with numerous health-related problems including fatigue, reduced cognitive and physical performance, increased anxiety and negative emotional states such as anger and depression. Children appear to be a particular risk group with respect to noise with research showing that environmental noise exposure negatively impacts cognition in children. These negative impacts include reduced reading and problem-solving ability as well as reduced attention span and motivation among noise-exposed children. Moreover, the most recent evidence suggests a link with mental health issues including emotional problems, conduct disorder, hyperactivity and antisocial behaviour.

TL;DR: People with higher levels of noise tolerance experienced more refreshing sleep, and housewives, non-smokers and individuals who were less anxious or stressed felt significantly more refreshed on waking up.
Abstract: Objective The aim of this study was to assess the impact of auditory noise tolerance on non-restorative sleep using an objective audiometric test in a representative sample. Design A total of 202 Chinese individuals aged 15 years and above were recruited from a population-based household survey. Their non-restorative sleep was assessed by a single item, the degree of feeling refreshed on waking up, on a 0–10 scale, while noise tolerance was measured by the most comfortable level expressed in A-weighted decibels. Results The 202 individuals (106 women) had a mean degree of feeling refreshed on waking up of 6.5 on the 0–10 scale and a mean maximum comfortable sound level of 69.2 dB. A multivariable analysis showed that a 1 dB increase in noise tolerance was associated with a 0.1-unit increase in the degree of feeling refreshed after adjusting for age, education, marital status, occupation, exercise, smoking, alcohol consumption, household noise level, stress, anxiety and depression. Moreover, housewives, non-smokers and individuals who were less anxious or stressed felt significantly more refreshed on waking up. Conclusion People with higher levels of noise tolerance experienced more refreshing sleep. Additional clinical consideration of enhancing noise tolerance in patients with sleep complaints is needed.

TL;DR: Techniques of recording, scoring, and doubtful records are carefully considered, and Recommendations for abbreviations, types of pictorial representation, order of polygraphic tracings are suggested.
Abstract: With the vast research interest in sleep and dreams that has developed in the past 15 years, there is increasing evidence of noncomparibility of scoring of nocturnal electroencephalograph-electroculograph records from different laboratories. In 1967 a special session on scoring criteria was held at the seventh annual meeting of the Association for the Psychophysiological Study of Sleep. Under the auspices of the UCLA Brain Information, an ad hoc committee composed of some of the most active current researchers was formed in 1967 to develop a terminology and scoring system for universal use. It is the results of the labors of this group that is now published under the imprimatur of the National Institutes of Health. The presentation is beautifully clear. Techniques of recording, scoring, and doubtful records are carefully considered. Recommendations for abbreviations, types of pictorial representation, order of polygraphic tracings are suggested.

TL;DR: A review of the relationship between noise exposure and the subjective reactions to it was conducted by as mentioned in this paper, which indicated that remarkably similar results have been obtained across different nationalities with different measurement techniques.
Abstract: Social surveys of the relationship between noise exposure and the subjective reactions to it were reviewed This review indicated that remarkably similar results have been obtained across different nationalities with different measurement techniques Only a small percentage (typically less than 20%) of the variation in individual reaction is accounted for by noise exposure Analysis of potential errors in both measurement of noise and reaction suggests that elimination of errors would only slightly increase the observed correlations Variables, such as attitude to the noise source and sensitivity to noise, account for more variation in reaction than does noise exposure The weaker relationship between noise exposure and attitude than between reaction and attitude suggests that the attitude/reaction relationship is not entirely due to noise exposure causing a change in attitude itself Noise/reaction correlations based on individual data are significantly lower in studies of impulsive noise than nonimpulsive noise This may be caused, in part, by the restricted range of noise exposure studied in some socioacoustic investigations of impulsive noise However, the significantly higher correlations of attitude and reaction in impulsive noise studies suggest that attitude plays an even larger part, while noise exposure plays a lesser part in determining reaction to impulsive noise, relative to nonimpulsive noise

TL;DR: Noise sensitivity levels did fall with recovery from depression but still remained high, suggesting an underlying high level of noise sensitivity, and was related to higher tonic skin conductance and heart rate and greater defence/startle responses during noise exposure in the laboratory.
Abstract: Noise, a prototypical environmental stressor, has clear health effects in causing hearing loss but other health effects are less evident. Noise exposure may lead to minor emotional symptoms but the evidence of elevated levels of aircraft noise leading to psychiatric hospital admissions and psychiatric disorder in the community is contradictory. Despite this there are well documented associations between noise exposure and changes in performance, sleep disturbance and emotional reactions such as annoyance. Moreover, annoyance is associated with both environmental noise level and psychological and physical symptoms, psychiatric disorder and use of health services. It seems likely that existing psychiatric disorder contributes to high levels of annoyance. However, there is also the possibility that tendency to annoyance may be a risk factor for psychiatric morbidity. Although noise level explains a significant proportion of the variance in annoyance, the other major factor, confirmed in many studies, is subjective sensitivity to noise. Noise sensitivity is also related to psychiatric disorder. The evidence for noise sensitivity being a risk factor for psychiatric disorder would be greater if it were a stable personality characteristic, and preceded psychiatric morbidity. The stability of noise sensitivity and whether it is merely secondary to psychiatric disorder or is a risk factor for psychiatric disorder as well as annoyance is examined in two studies in this monograph: a six-year follow-up of a group of highly noise sensitive and low noise sensitive women; and a longitudinal study of depressed patients and matched control subjects examining changes in noise sensitivity with recovery from depression. A further dimension of noise effects concerns the impact of noise on the autonomic nervous system. Most physiological responses to noise habituate rapidly but in some people physiological responses persist. It is not clear whether this sub-sample is also subjectively sensitive to noise and whether failure to habituate to environmental noise may also represent a biological indicator of vulnerability to psychiatric disorder. In these studies noise sensitivity was found to be moderately stable and associated with current psychiatric disorder and a disposition to negative affectivity. Noise sensitivity levels did fall with recovery from depression but still remained high, suggesting an underlying high level of noise sensitivity. Noise sensitivity was related to higher tonic skin conductance and heart rate and greater defence/startle responses during noise exposure in the laboratory. Noise sensitive people attend more to noises, discriminate more between noises, find noises more threatening and out of their control, and react to, and adapt to noises more slowly than less noise sensitive people.(ABSTRACT TRUNCATED AT 400 WORDS)
