The reactions of different residents to the same level of noise have been assumed to vary depending upon their type of housing and tenure status. However, no empirical evidence has been presented to support this assumption. The analysis described in this paper tests the separate and joint effects of housing type and tenure on various reactions to road traffic noise, with the use of questionnaire data and noise measurements collected at residential sites near to major highways in the Toronto region of southern Ontario. The results show that neither housing type nor tenure has any consistent effect on residents' reactions to road traffic noise. The working assumption in the literature is therefore not supported. Two important conclusions follow from this: first, that no one type of housing is clearly more appropriate in residential areas near to major highways; and second, that a policy of setting different noise standards for different types of residential area cannot be supported.

Exposure Levels

Introduction: Residents of modern cities and settlements are constantly exposed to noise. Excessive noise mainly attributed to road traffic ranks high among the complaints of the general population about living conditions. Careful selection of measuring sites plays an important role in monitoring noise exposure of the population. Current regulations and guidelines set the requirements for measuring and evaluating noise levels in a territory but provide no common approach to determining and selecting priority areas and noise measurement points, to establishing and substantiating appropriate observation periods, and to assessing health risks based on the exposure data. Materials and methods: In situ measurements were taken in residential areas of the historical center (four observation groups with 12 addresses) and new districts of the city (two observation groups with six addresses). Noise levels were measured at three points per address with three 5-minute measurements at a height of 1.5 ± 0.1 m above the ground taken per point. Points with the highest noise exposure levels were selected for organization of acoustic monitoring. Results and discussion: Six major observation groups were formed at 18 urban addresses. The results of measurement showed that statistically significant comparable levels of equivalent and maximum sound were registered in each group based on the same criteria and standard indicators. Grouping of addresses with similar or identical characteristics of observation zones will enable establishing noise exposures without conducting full-scale measurements. Additional observation groups can be formed in the presence of other indicators. Grouping of priority zones by location in observation groups will help register noise levels with minimal effort. Conclusions: Priority zones, points, periods of monitoring and surveillance in observation groups were established and justified. The findings served as the basis for elaboration of method approaches to monitoring and surveillance of road traffic noise exposure. Application of these approaches will contribute to increasing the efficiency of monitoring noise exposures of the population.

High Rise

Urban expressways can generate excessive noise in the surrounding urban areas, and it tends to be more complex in mountainous cities, due to the undulating terrain, dense population and compact urban structures. This article aims to investigate the objective acoustic environment and road traffic noise exposure, including the noisy evaluation, annoyance and effect of roadside apartments in residential areas close to urban expressways in the high-density, high-rise, mountainous city of Chongqing. Three housing estates were selected for a series of field measurements, questionnaire surveys and noise mapping. There was a significant negative correlation between night-time noise levels and the distances to the urban expressway ( p <  0.01). Moreover, the differences between the daytime and night-time noise levels were generally insignificant (0.7 to 3.6 dBA) at the roadside locations. Differences in reaction to noise exposure in a variety of both person-related and housing condition variables were found, especially between roadside and non-roadside locations or residents. In addition, 75.0% of roadside residents identified the traffic noise as ‘very’ or ‘extremely’ annoying, and 66.7% of them regarded the acoustic environment as the priority environmental factor that needs to be improved. Difference in the ‘bedroom-window orientation’ had a significant effect on subjective noise evaluation. Rectangular-shaped apartments along the roadside obtain better noise reduction capacities than tower-blocks through the simulation. The acoustic performance of road cuttings, as an appropriately designed earth embankment, is improved along with deeper vertical alignment, and slope angles of 30° and 75° should be avoided.

The City

Greece, as well as other developed countries, is facing the growing problem of road traffic noise. It stands for a severe problem in the urban areas of the country, including the city of Larissa. The root cause is the huge increase in traffic volume and the lack of adequate urban infrastructure planning. Estimation of the level of road traffic noise is usually conducted using acoustic meters. It is widely accepted that most of the cities’ population is exposed to high noise levels due to controversial traffic capacity. Moreover, high noise levels are strongly related to phycological and neurological diseases. Thus, it is of utmost importance, the road noise levels to be lower than dictated by relevant specification limits. To develop better noise-environment policies, relative research should focus on the measurement of in-situ noise levels, so as appropriate for each case corrective measures to be taken. The present paper examines the noise levels of a center road of the 5th Greek city, in terms of population, compared to worldwide adopted noise specification limits. The clear aim stands for finding the percentage of road noise that exceeds commonly accepted threshold values, namely limit values of European Union and World Health Organization. The results of this research strongly indicate that measured noise values override upper limit values in a certain extent.

Noise Impact

Investigation of the factors affecting individual response to noise provides an improved basis for the selection and implementation of noise impact reduction policies. This investigation is necessary because the cause and effect relationship between the level of noise exposure and noise response is confounded by personal and situational variables. Examination of the effects of these variables on response to road traffic noise with the use of data collected at residential sites in Southern Ontario suggests the following points for residential planning decisions. Arguments for taking no action to reduce noise impact are not supported. The sex, age, and socioeconomic compositions of residential areas are not important considerations for implementing measures to reduce noise impact. Life-style characteristics of residents on the other hand do affect response to noise. Methods to reduce noise must be effective indoors and outdoors to have a significant effect on attitudes: air conditioning alone is inadequate. Noise barriers appear to be more effective for improving attitudes than their noise reduction properties would suggest.

The Impact

Low-noise thin asphalt layers (TALs) are a feasible solution to mitigate road traffic noise in urban environments. Nevertheless, the impacts of this type of noise intervention are reported mostly regarding noise levels, while non-acoustic aspects influencing the population perception are still little-known. This study investigates the implementation of TALs in two streets of Antwerp, Belgium. The effectiveness of the intervention was measured via noise modelling and acoustic measurements of road traffic noise. A reduction of 2.8 dB in noise exposure was observed in Lden and Lnight, while SPB measurements showed decreases up to 5.2 dB on the roadside. The subjective impacts of the TALs were evaluated via self-administered surveys and compared to results from control streets. The annoyance indicators were positively impacted by the TALs implementation, resulting in annoyance levels similar or lower than in the control streets. The TALs did not impact the reported physical complaints, sleep quality, and comfort level to perform activities.

The Calculation of Road Traffic Noise (CRTN) model is one of the first traffic noise prediction models in the world and has been widely used in many Western countries. However, its performance in a motorcycle city has not been well assessed. This study aims to examine the accuracy of the CRTN model in predicting traffic noise in an Asian city with over half of motor vehicles being motorcycles. The performance of the CRTN model in predicting both roadside and vertical distributions of traffic noise levels is assessed. The results show that the performance of the CRTN model is satisfactory in predicting roadside traffic noise levels, with anR2of 0.832 and a mean difference of +0.52 dB(A) between the measured and predicted values. The performance of the CRTN model is also satisfactory in predicting vertical distribution of traffic noise levels, with anR2of 0.836 and a mean difference of +0.28 dB(A) between the measured and predicted values.
