ANNOYANCE AND COMMUNITY NOISE: PSYCHOPHYSICAL MODEL OF DOSE – RESPONSE RELATIONSHIPS

There is a paucity of theory pertaining to social surveys of annoyance and community noise. A new psychophysical model addresses data concerning resident annoyance in sites exposed to various maximum noise levels and different numbers of noise events. The best fits of this model point to the relevance of response variance for understanding the results obtained with category response scales. The argument identifies a number of psychological and physical variables that may influence annoyance reactions to community noise. Most importantly, the model suggests that the truncation inherent in category scales biases the responses, and that response variability may be critical in determining the detailed shape of the dose–response function. Regulatory decisions concerning annoyance and community noise should be more valid when based on a deeper understanding of the theoretical basis of the empirical data.     

Noise annoyance from industrial and road traffic combined noises: A survey and a total annoyance model comparison

The literature on noise annoyance emphasizes that acoustical factors cannot totally explain the annoyance felt by a population exposed to community noises, and that some non-acoustical factors have an effect on annoyance. This research paper deals with the annoyance caused by combined noises coming from road traffic and an industrial site. This type of combination has been very little studied to date. An in situ study was conducted in an area of a French town exposed to these two noise sources. To investigate the annoyance caused by these combined noises, the work involved both a mapping of the industrial and road traffic noises present in the survey area and a questionnaire designed to evaluate the noise annoyance experienced by residents and to identify the factors that probably influence noise annoyance. The results highlight the link between the noise levels measured and the annoyance felt by the respondents. They also show that certain non-acoustical factors have an impact on annoyance felt. Indeed, the results highlight a positive correlation between fear of industrial sites and the annoyance expressed. They also show correlations between some items to evaluate noise sensitivity and the annoyance expressed. No significant correlation has been found between annoyance and the other non-acoustical factors such as age, sex and length of residence. Finally, several total annoyance models were tested for this noise combination. Two of them, namely the strongest component model and a proposed perceptual version of the mixed model, were able to better predict total annoyance than the other tested models.     

The acceptability of wind farms: the impact of public participation

The planning process for wind farm projects appears to be a complicated matter in many cases. Despite the positive attitude towards wind power in general, local wind farm projects often face strong opposition. The aim of this study is to shed more light on residents’ perceptions of participation in the planning process of wind farms. This study is based on interview data (N?=?22) and survey data (N?=?291) collected from residents living near two Finnish large-scale onshore wind farms built about 1.5 years before the data were collected. The results indicate that residents’ participation in the planning process was rather passive and the vast majority of the respondents perceived that they did not have an opportunity to participate. Quite interestingly, perceived participation in the planning process resulted in a decrease in acceptability in terms of perceived well-being. Furthermore, the results indicate that the need for participation does not expire after the planning process for a wind farm has concluded. Thus, project developers should be prepared to continue communication with residents after the planning phase.     

Community opinion concerning airport noise-abatement alternatives

In the present study we examined (1) community opinion of airport noise-abating alternatives and (2) the influence of perceived control on attitudes concerning noise-abatement policies and annoyance toward aircraft noise. We proposed that residents who perceive themselves as having little control over aircraft noise exposure would express higher levels of annoyance than residents who believe they have some degree of control. Furthermore, residents with low levels of perceived control would be less favorable toward proposed noise-abatement alternatives. Survey results collected from 239 households within the 65 CNEL contour of a community airport in Southern California support these hypotheses. Findings indicate strong public support for noise abatement and strong opposition to land-use alternatives. In addition, residents' perceptions of control in the airport planning and management process are significantly related to their annoyance with noise and their opinions about noise management policies.     

Different Shades of Green: A Case Study of Support for Wind Farms in the Rural Midwest

Benton County, in north-central Indiana, USA has successfully sited more than 500 turbines. To understand Benton County’s acceptance of wind farms, a holistic case study was conducted that included a document review, a survey of local residents and interviews with key stakeholders. Survey questionnaires were sent to 750 residents asking questions about attitudes toward the wind farms, perceived benefits and impacts from the wind farms, environmental attitudes, and demographic information. Key stakeholders were also interviewed for a deeper understanding of the historical timeline and community acceptance of the wind farm development. While there is limited opposition to the turbines, on the whole the community presents a front of acceptance. Financial, rather than environmental, benefits are the main reason for the acceptance. Although significant in other case studies, transparency and participation do not play a large role in Benton County’s acceptance. Most residents are not concerned with either visual impacts or noise from the wind turbines. More concrete benefits to the community, such as reduced energy bills for county residents, could help to extend acceptance even further within the community. Although there are concerns about the acceptance of wind farms and the impacts of those farms on local residents in both peer-reviewed literature and popular media, we found little evidence of those concerns in Benton County. Instead, we found Benton County to be a community largely accepting of wind farms.     

Noise annoyance responses of middle school pupils and teachers

The present survey study had three aims: (1) to compare pupils’ and teachers’ annoyance responses to classroom noise, (2) to compare females and males responses and (3) to test annoyance models that fitted both pupils and teachers. The study included 207 pupils, aged 13–14 years, and 166 teachers, aged 21–65 years. Both pupils and teachers rated chatter as the most disturbing noise source in the classroom. In line with predictions, the teachers experienced themselves as more sensitive to noise, had poorer hearing status, and reported more intense stress symptoms than the pupils. Contrary to expectations, the teachers were more annoyed and they perceived the noise to be more unpredictable than the pupils did. The control items showed a mixed pattern. There were no overall differences between females and males annoyance responses, but females reported having more stress symptoms than males. A conceptual model was tested with structural equation models, where noise sensitivity mediated the relationship between hearing status and annoyance, which in turn affected stress symptoms. Control and predictability were tested as moderators of the relations between stress symptoms and annoyance. The data fit the conceptual model reasonable well when both samples were included in the same test.     

Policy, personal dispositions and the evaluation of aircraft noise

In this paper, we hypothesize and test the ideas that (1) people’s subjectivity in relation to aircraft noise is shaped by the policy discourse, (2) this results in a limited number of frames towards aircraft noise, (3) the frames inform people how to think and feel about aircraft noise and (4) the distribution of the frames in the population is dependent on structural variables related to the individual. To reveal subjects’ frames of aircraft noise a latent class model is estimated based on survey data gathered among a sample of 250 residents living near Amsterdam Airport Schiphol, a major international airport in the Netherlands. In line with expectations, the results show that there are four evaluative frames of aircraft noise, three of which are strongly linked to the policy discourse. The frames are associated with fitting levels of annoyance response. In turn, frame membership is influenced by two structural variables, namely aircraft noise exposure and noise sensitivity. The results indicate that social factors operate discursively in the explanation of subjective reaction to noise, while psychological factors operate within a traditional cause-and-effect model. The paper concludes with several policy implications.     

Industrial odours as environmental stressors: Exposure-annoyance associations and their modification by coping, age and perceived health

The degree of association between industrial odours and reported annoyance was investigated by means of field studies in four German cities, namely Duisburg (n = 400), Brühl (n = 539), Dortmund (n = 400) and Rodenkirchen (n = 200). The degree of odour exposure was assessed by estimating the frequency of odours by means of systematic field observations, whereas annoyance was assessed by personal interviews using standardized questionnaires. Both studies revealed highly significant associations between odour exposure and degree of annoyance. Odour annoyance was correlated with personal factors: age was negatively related to annoyance, whereas dissatisfaction with health exhibited positive associations with annoyance. Coping strategies were also associated with odour annoyance: high scores in problem-oriented coping strategies increased annoyance, whereas high scores in avoidance coping reduced annoyance. Coping strategies based upon the reduction of emotional stress were not associated with annoyance. Since none of the interaction terms of the full regression model proved significant, no true moderators were identified. In order to check for aquiescence bias, people who were interviewed personally were compared with those who could not be approached directly and who were therefore contacted by mail. Despite some significant differences in terms of gender, education, occupation, problem-oriented coping and avoidance coping, both groups did not differ in terms of annoyance.     

Sustainability versus liveability: an investigation of neighbourhood satisfaction

Recent years have witnessed an increasing emphasis placed on planning systems in most advanced capitalist societies to develop a more sustainable urban development pattern, resulting in policies to increase residential densities. Although belief in the virtues of the compact city approach is now widespread among the policy community, questions remain relating to the ‘sustainability versus liveability’ implications of compact city environments. In this regard, while the public may support sustainability principles, there is a perception that high-density development poses too great a cost on individuals' quality of life. Combining both quantitative and qualitative research data, this paper evaluates the relationship between high-density living and neighbourhood satisfaction within the central city. Findings suggest that, in many instances, it is not high density per se that is the source of dissatisfaction for respondents, but rather other related factors such as environmental quality, noise, lack of community involvement, traffic and lack of services and facilities.     

Community noise problems: Evidence against adaptation

It is commonly believed that people adapt rather easily to noise. This article reviews the available research, finding little evidence that any adaptation occurs in community settings. Much of this research, however, is open to alternative interpretations. The present study, examining reactions to traffic noise from the opening of a major new highway, was designed to remedy many of the problems with previous research. The investigation incorporated both a repeated measures design (the same respondents were interviewed 4 and 16 months after the highway opening) and an independent groups design (separate groups were interviewed either 4 or 16 months after opening). In addition, a pre-opening interview was carried out with the repeated measures panel. There was no evidence of appreciable adaptation in self-reported noise effects, annoyance, or tendency to focus attention on the noise. Instead respondents became more pessimistic about their ability to adapt to noise as time went by.     

Visual Perception of Habitats Adopted for Post-Mining Landscape Rehabilitation

The study presented here focuses on visual preferences expressed by respondents for five relatively natural habitat types used in land reclamation projects in the North-West Bohemian brown coal basins (Czech Republic). Respondents evaluated the perceived beauty of the habitat types using a photograph questionnaire, on the basis of the positively skewed 6-point Likert scale. The order of the habitat types, from most beautiful to least beautiful, was: managed coniferous forest, wild deciduous forest, managed deciduous forest, managed mixed forest, and managed grassland. Higher visual preferences were indicated for older forest habitats (30–40 years old) than for younger habitats (10–20 years old). In addition, respondents preferred wild deciduous forest to managed deciduous forest. Managed grasslands and non-native managed coniferous forests were preferred by older people with a lower level of education and low income living in the post-mining area. On the other hand, native, wild deciduous forest was awarded the highest perceived beauty score by younger, more educated respondents with higher income, living outside the post-mining landscapes. The study confirms differences in the perception of various forms of land reclamation by residents vs. non-residents, and its findings also confirm the need for sociological research in post-mining landscapes within the process of designing rehabilitated landscapes. From the visual standpoint, the results of our study also support the current trend toward using natural succession in the reclamation of post-mining landscapes.     

Electromagnetic fields and other physical factors around wind power generators (pilot study)

According to the 20/20/20 strategy by European Union for green energy by 2020 priority should be given to the Renewable Energy Sources. The energy generated from the wind has proven to be of interest for several reasons—wind is available, it is a cheap, and virtually inexhaustible source of energy. In this relation in the last years, many wind power stations were built all around the country. They are being located in proximity of populated areas. Their work besides the generation of electricity is connected to emission of physical factors in the environment that could be essential for human health. In order to avoid overexposure to electromagnetic fields, noise, and vibration to the general public minimal safety distance is being determined theoretically for ‘worst case” conditions basing on the technical characteristics of the generators. After the mounting of installations, measurements have to be performed to determine whether the national and European safety limits for the factors of environment are being kept. The paper presents results of measurement of electromagnetic fields, additionally noise and vibration around one of the biggest wind power parks in Bulgaria. The measurements were made in the close proximity of the generators both for the personnel working conditions and for the population in the closest living areas.     

On the wind resource mapping of Burkina Faso

In this work, mesoscale wind resource maps, at 5-km resolution, of the country of Burkina Faso (274,200 km²) were developed using the Anemoscope and mesoscale compressible community models. Results show that the northeast region of Burkina Faso has a good wind regime at 80 m above ground level (agl), while the wind regime in other parts of the country is generally low, even at 80 m agl. In addition, the technical power potential and the potential annual energy production that can be generated from the wind in Burkina Faso are identified using analysis tools based on geographical information systems and economic constraints. Results from the technical power potential at 80 m agl show that a total of 312 MW of wind farms, generating annually a total of 741 GWh of energy, could be installed in Burkina Faso. On the other hand, a total of 4411 MW of small wind turbines (50 kW) could be installed over the territory, corresponding to an annual energy production of 7843 GWh. The Wind Atlas of Burkina Faso provides an opportunity for local stakeholders to consider wind energy for the electricity portfolio of the country.     

“It's easy to throw rocks at a corporation”: wind energy development and distributive justice in Canada

In places like Canada, fast-paced wind turbine development combined with policy that limits local decision-making power has resulted in strong opposition to specific projects. Some studies suggest that anti-wind sentiment is tied to inadequate financial benefits – especially sharing at the local level. Thus, ideas of distributive economic justice have received traction, particularly in the form of praise for community-based development models. This paper reports on the findings from a mixed-methods study concerning preferred distributive justice elements in rural communities in Ontario (technocratic-based model) and Nova Scotia (community-based model) living with turbines. Residents’ perceptions of economic benefits are nuanced, but unlike other studies, this empirical work shows that both the fair distribution and the amount of local benefits are important predictors of project support. Yet, concerns around the fair distribution of benefits dominate in a regression on the adequacy of those benefits. A variety of interview and survey findings further point to the strength of traditional, profit-sharing community-based models for distributing benefits, but also more novel ideas including lowered electricity bills and tax rebates in areas home to turbines.     

Combining a participatory planning approach with a virtual landscape model for the siting of wind turbines

The Swiss Federal Institute of Technology ETH Zürich is planning to build three wind turbines for the production of renewable energy. Their proposed location is near the campus of ETH Hönggerberg in the Käferberg open space. This open space is of high importance for the recreation of the local residents. It is one of the last open spaces in Zürich that is used agriculturally. In order to provide a broad forum for discussion and to examine the level of acceptance of the proposed wind turbines a new approach to participatory planning is pursued by introducing a virtual landscape model to a participatory planning workshop for which the different interest groups and stakeholders were invited. During the workshop different alternatives were discussed and suggested changes by the participants were incorporated in the 3D model and visualized. The results of the workshop show that 3D visualization is an important means of communication among the different interest groups. The workshop also shows that an early integration of 3D visualization combined with a participatory approach is an effective way to elucidate potential conflicts at an early stage of the planning process.     

The role of NIMBY in opposing the siting of wind farms: evidence from Greece

This paper aims to assess the relative importance of a NIMBY (‘Not-In-My-Back-Yard’) stance on an individual's opposition to the siting of a wind farm vis-à-vis other predictors, such as perceived effects (costs, risks and benefits associated with the project), perceived fairness of the siting decision and societal trust. Data originate from two case studies, a small wind farm of just two wind turbines in southern Greece and a mega-project of 153 turbines on the Greek island of Lesvos (aggregate N = 334). We use structural equation modelling (SEM) for testing the theoretically-suggested relations between the various constructs. We find that NIMBY is not the most important predictor of opposition while it is strongly correlated with other predictors, such as the perceived unfairness of the siting decision as well as the risks and costs associated with the wind farm. These latter findings undermine the common-sense idea that wishing a wind farm out of one's vicinity (‘Not-In-My-Back-Yard’) is an example of mere ‘free-riding’. Since the fit of the SEM models was found to be moderate, we discuss the limitations of our study and the implications of our findings as well as suggesting pathways for future research.     

THE RESTON (VIRGINIA) LAKE-USE SURVEY: PUBLIC PERCEPTIONS AND MANAGEMENT IMPLICATIONS1

ABSTRACT: A public attitude survey was developed by a citizen committee and mailed to all residences (14,747) in the planned, suburban community of Reston, Virginia, which is responsible for maintaining four small, recreational impoundments. Over 18 percent of survey forms were returned, and characteristics of the survey sample suggest that the suite of respondents was representative of the Reston community as a whole. Of those respondents indicating a preferred lake use, 48 percent chose walking or looking as most important; boating as second at 27 percent; and fishing was third, favored by only 8 percent. Citizens feel strongly (94 percent) that the lakes are valuable community assets. Appearance was the characteristic most valued by 62 percent of respondents, and 58 percent considered degradation of water quality either the first or second most important ecological issue affecting local lakes. These findings provide a decisive public mandate for lake management activities related to visual quality. In response to this survey, the Reston Association, a homeowners' organization responsible for the lakes, increased public access of visual enjoyment, intensified litter control, expanded activities in public education on lake management and ecology, and continued a long-term program of water quality monitoring.     

Wind energy potential analysis for Thailand: Uncertainty from wind maps and sensitivity to turbine technology

Rapid development of wind energy has been witnessed in Thailand. However, different wind resource maps (over land) have brought great uncertainty to wind energy planning. Here, four important mesoscale wind maps were considered: DEDP (2001), World Bank (2001), Manomaiphiboon et al. (2010) of JGSEE, and DEDE (2010). The wind maps were first harmonized to a common grid at 100 m and then compared. The earlier wind maps (DEDP and World Bank) are shown to represent the lower and upper limits of predicted speed, respectively, while JGSEE and DEDE tend to be more moderate with predictions statistically closer to observations. A consolidated wind map was constructed based on their median and shown to have the best prediction performance. It was then used for the technical potential analysis, in which three large (2-MW) turbine models (two conventional and one designed for low wind speed) were considered. By GIS techniques, any land areas not feasible for large wind turbines were excluded, and the corresponding overall onshore technical potential ranges between 50 and 250 GW, depending on map and turbine model. Considering only economically feasible turbines (with capacity factors of 20%) and the median-based map, the final technical potential equals 17 GW when using the low-wind-speed model but is reduced to 5 GW with the conventional models, adequately meeting the national wind energy target of 3 GW by the year 2036. The results suggest a strong sensitivity of estimated technical potential to turbine technology and a suitability of low-wind-speed turbines for wind conditions in Thailand.     

Environmental concern, attitude toward frugality, and ease of behavior as determinants of pro-environmental behavior intentions

This study investigates relations between environmental concern, attitude toward frugality, perceived ease of behavior, and stated intentions to engage in four different types of pro-environmental behavior, i.e., reductions in electricity and gas use, garbage, and automobile use, using data from 341 Japanese respondents. Environmental concern, attitude toward frugality and perceived ease of implementation were considered possible determinants. A structural equation analysis indicated that perceived ease of implementation had effects for all of the pro-environmental behaviors. It also indicated that environmental concern had a positive effect solely for garbage reduction, while attitude toward frugality had positive effects for gas and electricity reduction. For automobile use reduction, neither environmental concern nor attitude toward frugality had significant effects. The relationship between attitude toward frugality and mottainai, that is a Japanese concept indicating respect for resources, is then discussed, and it is suggested that educating people to have not only a high level of environmental concern but also a positive attitude toward frugality would be an effective means of promoting pro-environmental behavior.
