TL;DR: In this paper , the authors conducted a field study in residential areas where road traffic was the dominant noise source, and noise events were attributable to separate vehicle pass-bys, and established an exposure-response relationship for the awakening probability due to intermittent road traffic noise in suburban residents.

TL;DR: To compare sleep disturbance model predictions,ight operations data from United States airports were obtained and sleep disturbance in communities was predicted for different operations scenarios using the modified Markov model, the nonlinear dynamic model, and other aircraft noise awakening models.
Abstract: One of the primary impacts of aircraft noise on a community is its disruption of sleep. There are models that have been developed to predict the effect of aircraft noise on sleep. However, most of these models only predict the percentage of the population that is awakened. Markov and nonlinear dynamic models have been developed to predict an individual’s sleep structure during the night. However, both of these models have limitations. The purpose of this research was to examine these sleep structure models to determine how they could be altered to predict the effect of aircraft noise on sleep. Different approaches for adding a noise level dependence to the Markov Model was explored and the modified model was validated by comparing predictions to behavioral awakening data. In order to determine how to add faster dynamics to the nonlinear dynamic sleep models it was necessary to have a more detailed sleep stage classification than was available from visual scoring of sleep data. An automatic sleep stage classification algorithm was developed which extracts different features of polysomnography data including the occurrence of rapid eye movements (REMs), sleep spindles, and slow wave sleep. Using these features an approach for classifying sleep stages every one second during the night was developed. From observation of the results of the sleep stage classification, it was determined how to add faster dynamics to the nonlinear dynamic model. Slow and fast REM activity are modeled separately and the activity in the gamma frequency band of the Electroencephalogram (EEG) signal is used to model both spontaneous and noise-induced awakenings. The nonlinear model predicts changes in sleep structure similar to those found by other researchers and reported in the sleep literature and similar to those found in obtained survey data. To compare sleep disturbance model predictions, flight operations data from United States airports were obtained and sleep disturbance in communities was predicted for different operations scenarios using the modified Markov model, the nonlinear dynamic model, and other aircraft noise awakening models. Similarities and differences in model predictions were evaluated in order to determine if the use of the developed sleep structure model leads to improved predictions of the impact of nighttime noise on communities.

TL;DR: According to the meta-analysis based on data from a large number of studies the proportion annoyed varies between the different noise sources, e.g. aircraft noise is most annoying followed by road traffic and railway noise (15 % annoyed) at Lden 60 dB.
Abstract: A “bonus” of 5 dB has been applied to railway noise in most European Union (EU) countries, e.g. Austria, Germany, France and Sweden. The reason for this is that the majority of international and Swedish studies show that railway noise is less annoying than road traffic noise and aircraft noise (Miedema & Oudshoorn 2001; EU position paper 2002). According to the meta-analysis (Miedema & Oudshoorn 2001) based on data from a large number of studies the proportion annoyed varies between the different noise sources, e.g. aircraft noise is most annoying (38 %) followed by road traffic (26 %) and railway noise (15 % annoyed) at Lden 60 dB.

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: In this article, the authors present technical prescriptions concerning the design and construction of agricultural or forestry tractors, as regards the rollover protection structures, as well as the approximation of the laws of the Member States to enable the EC typeapproval procedure provided for in Directive 2003/37/EC to be applied in respect of each type of tractor.
Abstract: (2) Directive 77/536/EEC is one of the separate Directives of the EC type-approval system provided for in Council Directive 74/150/EEC of 4 March 1974 on the approxi­ mation of the laws of the Member States relating to the type-approval of wheeled agricultural or forestry tractors, as replaced by Directive 2003/37/EC of the European Parliament and of the Council of 26 May 2003 on type-approval of agricultural or forestry tractors, their trailers and interchangeable towed machinery, together with their systems, components and separate technical units ( 5 ), and lays down technical prescriptions concerning the design and construction of agricultural or forestry tractors, as regards the roll-over protection structures. Those technical prescriptions concern the approximation of the laws of the Member States to enable the EC type-approval procedure provided for in Directive 2003/37/EC to be applied in respect of each type of tractor. Consequently the provisions laid down in Directive 2003/37/EC relating to agricultural and forestry tractors, their trailers and interchangeable towed machinery, together with their systems, components and separate technical units, apply to this Directive.

TL;DR: Better estimates of the confidence intervals due to the improved model of the relationship between annoyance and noise exposure are provided, which is easier to use for practical calculations than the model itself.
Abstract: We present a model of the distribution of noise annoyance with the mean varying as a function of the noise exposure. Day-night level (DNL) and day-evening-night level (DENL) were used as noise descriptors. Because the entire annoyace distribution has been modeled, any annoyance measure that summarizes this distribution can be calculated from the model. We fitted the model to data from noise annoyance studies for aircraft, road traffic, and railways separately. Polynomial approximations of relationships implied by the model for the combinations of the following exposure and annoyance measures are presented: DNL or DENL, and percentage "highly annoyed" (cutoff at 72 on a scale of 0-100), percentage "annoyed" (cutoff at 50 on a scale of 0-100), or percentage (at least) "a little annoyed" (cutoff at 28 on a scale of 0-100). These approximations are very good, and they are easier to use for practical calculations than the model itself, because the model involves a normal distribution. Our results are based on the same data set that was used earlier to establish relationships between DNL and percentage highly annoyed. In this paper we provide better estimates of the confidence intervals due to the improved model of the relationship between annoyance and noise exposure. Moreover, relationships using descriptors other than DNL and percentage highly annoyed, which are presented here, have not been established earlier on the basis of a large dataset.
