TL;DR: In this paper, an approach for predicting instantaneous sound levels caused by road traffic is presented, which takes into account a measured distribution of sound power levels produced by individual vehicles, for each vehicle category.
Abstract: Research evidence suggests that annoyance, sleep disturbance and other health effects of road traffic noise exposure may be related to the level and number of noise events caused by traffic as well as to energy equivalent measures of exposure. Because measurements show that the variation in noise emission between vehicles within the same category can be considerable, it is essential that the influence of vehicles that are producing significantly more (or less) noise than the average vehicle are taken into account in order to correctly predict the occurrence and strength of road traffic noise events (and in particular to calculate indicators that characterize these noise events). However, current state-of-the-art instantaneous vehicle noise emission models usually only consider a single emission law for each vehicle class. In this paper, an approach for predicting instantaneous sound levels caused by road traffic is presented, which takes into account a measured distribution of sound power levels produced by individual vehicles, for each vehicle category. The effect of this approach on estimated energy equivalent levels, percentile levels and sound event indicators is investigated for the simplified setting of a receiver along a dual-lane road carrying free flow traffic.

TL;DR: In this paper, a methodical comparison of simulated and experimental data is made, in order to test the perfection and behaviour of the models in different studied sites in an Indian road condition.
Abstract: Noise pollution has become a major concern of communities living in the vicinity of highways/road corridors, and intersections. The recognition of highway noise, as one of the main sources of environmental pollution led to design models that enable us to predict traffic noise level. Several models have been developed to predict traffic noise along the highways from fundamental variables such as noise descriptors. Experimental data are gathered for seven squares along the National Highway-316 (connecting Bhubaneswar to Jagannath Dham, Puri) in the present study. Noise pollution was analysed in seven different squares (road sections) during morning, afternoon and evening to assess the level of noise pollution along this road. A methodical comparison of simulated and experimental data is made, in order to test the perfection and behaviour of the models in different studied sites in an Indian road condition. Co-relation coefficient is applied to infer the level of significance.

TL;DR: The study results support an association between higher nocturnal road traffic noise and self-reported sleep disturbance in comparison to areas with quieter nights and sleep disturbance among women was significantly associated with higher night noise exposure.
Abstract: Background: Previous studies have provided evidence about chronic night noise exposure and sleep disturbance, which is indicator of more serious health conditions. Such studies have never been reported for the Indian population. This study aimed to further explore the association between nocturnal transportation noise exposure and self-reported sleep disturbances in an adult Indian population.Methods: The cross-sectional study used results from a pilot study, from a large scale social survey in the urban municipality of Asansol, an industrial city, situated in western India. The survey included responses from 221 adults (19-59 year old) residing within 100 meters buffer of the major and arterial roadways, with criteria of minimum 10 years stay in the study area. Association of self-reported sleep disturbance was studied by multiple logistic regression analysis with adjusting for age, gender and period of residence.Results: Sleep disturbance was more marked at levels of 61-65 dB(A) night noise exposure, OR...

TL;DR: In this paper, a framework for consistent, contextsensitive modeling of road transport noise emissions from road transports in LCI is proposed, which is based on the Swiss EPA method and the Danish LCA guide method.
Abstract: Background, aim, and scope An inclusion of traffic noise effects could change considerably the overall results of many life cycle assessment (LCA) studies. However, at present, noise effects are usually not considered in LCA studies, mainly because the existing methods for their inclusion do not fulfill the requirement profile. Two methods proposed so far seem suitable for inclusion in generic life cycle inventory (LCI) databases, and a third allows for inter-modal comparison. The aim of this investigation is an in-depth analysis of the existing methods and the proposition of a framework for modeling road transport noise emissions in LCI in accordance to the requirement profile postulated in part 1. Materials and methods This paper analyzes three methods for inclusion of traffic noise in LCA (Danish LCA guide method, Swiss EPA method, and Swiss FEDRO method) in detail. The additional basis for the analysis are the Swiss road traffic emission model “SonRoad,” traffic volume measurements at 444 sites in the Swiss road network, vehicle-type-specific noise measurements in free floating traffic situations in Germany, and noise emission measurements from different tires. Results The Danish LCA guide method includes a major flaw that cannot be corrected within the methodological concept. It applies a dose–response function valid for average noise levels of a traffic situation to maximum noise levels of single vehicles. The Swiss FEDRO method is based on an inappropriate assumption since it bases distinctions of specific vehicles on data that do not allow for such a distinction. Noise emissions cannot be distinguished by the make and type of a vehicle since other factors, especially the tires, are dominant for noise emissions. Several problems are also identified in the Swiss EPA method, but they are not of a fundamental nature. Thus, we are able to base a new framework for vehicle and context-sensitive inclusion of road traffic noise emissions in LCI on the Swiss EPA method. We show how specific vehicle classes can be distinguished, how the influence of different tires can be dealt with, and what temporal and spatial aspects of traffic need to be distinguished. Discussion While the Danish LCA guide method and the Swiss FEDRO method are not suitable for our purpose, the Swiss EPA method can be used as a basis to better meet the requirement profile identified in Part 1 of this paper. The proposed method for consistent, contextsensitive modeling of noise emissions from road transports in LCI meets all the requirements except that it is

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.
