Building Facades

Urban road traffic noise in cities is an ongoing and increasing problem across much of the world. Consequently a large amount of effort is expended in attempts to address this problem, especially in the area of acoustic design of buildings. Acoustic design policies developed by government authorities will typically focus on required transport noise reductions through a building façade to meet a specified internal noise levels. The significance of balcony acoustic treatments has been highlighted in recent decades yet this area has potentially been considered less important than the need for acoustic isolation of building facades. This paper outlines recent research that has been conducted in determining the significance of balcony acoustic treatments in mitigating urban road traffic noise. It summarizes recent literature, some of which focuses on technological advances in the knowledge of balcony acoustic design and some literature discusses the overall aims and benefits of balcony acoustic design. The aim of this paper is to promote the use of balcony acoustic design as a significant element in the overall solution towards mitigating road traffic noise in modern cities.

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.

Abstract Purpose Road traffic noise is the most common source of noise in modern cities. The noise indicators used to manage noise do not take into account its temporal structure. However, in cities the traffic flow varies during the day, peaking due to congestion and more fluent periods. In this research we sought to analyze how people (giving answers on a numerical ICBEN scale) perceive noise stimuli with the same LAeqT values but different time structures (more/less noise events, different amplitude envelopes). Methods 31 people with normal hearing took part in an experiment conducted in an anechoic chamber. Participants listened to 18 different noise recordings and rated each of them using the numerical ICBEN scale regarding noise annoyance. Results The results showed that only sound level was a statistically significant factor. However, based on people’s remarks about noise, we can also say that the more intermittent the noise is, the more negative feelings it evokes in people. Conclusions Time structure does not have a significant influence on people’s judgments about noise annoyance. However, people tend to have a preference for a steady noise rather than an intermittent one.

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.

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.
