“…There have been numerous studies concerning noise, its sources, pollution levels, effects, human health, etc., over the last years, and the topic is still of medical and scientific interest as shown by the different studies published in recent years like in Zannin et al (2002), Murphy and King (2011), Barrigón-Morillas et al (2010) and Jakovljevic et al (2009). In the case of industrial wastes, in the last years disposal of scrap tyres has became one of the major environmental problems.…”

This paper reports an investigation of a new kind of material and its acoustical performance. The main component of this porous absorber is the ground tyre rubber (GTR) with different particle sizes, from the shredding of tyres of heavy vehicles, mixed with different proportion of polyurethane resin. Acoustical properties were assessed according to ISO 10534-2: 1998. The data obtained show porous absorbers having a high sound absorption performance with low thicknesses and compared to some of the current models for the prediction of their absorptive properties. The use of this model constitutes a good tool in order to design a new sound absorber to solve two environmental problems, noise and environmental pollution.

“…A partir desses resultados é, então, possível alcançar a compreensão da aparente contradição entre a conclusão obtida no estudo do ruído urbano de Curitiba (Zannin et al, 10 2001) e as respostas à pergunta: "Na sua opinião, o ruído de sua rua aumentou?". Na metodologia adotada por esse estudo, a fonte predominante na grande maioria dos pontos medidos era o ruído gerado pelo trânsito.…”

Descreve-se a reação da população de Curitiba, PR -- cidade com aproximadamente 1,6 milhões de habitantes --, ao ruído ambiental . Os dados foram coletados por meio de questionários distribuídos aleatoriamente a moradores da cidade. Dos 1.000 questionários distribuídos, 860 (86%) foram avaliados. As principais fontes de ruído causadoras de incômodo identificadas foram o tráfego de veículos (73%) e os vizinhos (38%), sendo que estes foram classificados como a principal fonte de desconforto. Todos os respondentes apontaram pelo menos um dos seguintes itens como geradores de ruído: vizinhos, animais, sirenes, construção civil, templos religiosos, casas noturnas, brinquedos e aparelhos domésticos. As principais reações ao ruído foram: irritabilidade (58%), baixa concentração (42%), insônia (20%) e dores de cabeça (20%).

“…Especially, the noise that occurs in urban areas based on traffic volume is a kind of pollution, influencing the quality of life directly in today's cities. Moreover, it is the primary problem, which requires indispensable solutions (Murphy, King, 2014; Goldsmith, 2012; Zannin et al, 2002;Berglund et al, 1999;Arana, Garcia, 1998). 90% of passenger transportation and cargo are carried out via highways in Turkey (Ç olakkadıoǧlu, Yücel, 2017).…”

In this study, traffic noise in Seferihisar, which is a holiday resort by the Aegean Sea in the West of Turkey, was investigated. The noise occurring in summer and winter, on weekdays, and at weekends was mapped separately. Besides, land uses exposed to traffic noise were specified. In the carried out method, the land uses were primarily mapped by using the satellite images of the study area. Then, the noise was measured at 46 points during ten days in summer and winter, on weekdays and at weekends, and it was mapped by using Inverse Distance Weighting (IDW) method and by means of Geographic Information System (GIS) techniques. The measurements were taken in the daytime (07:00-19:00), in the evening (19:00-23:00), and at night (23:00-07:00) as stated in the Turkish Regulation of Assessment and Management of Environmental Noise. Since the time interval of the daytime measurements was large, the noise was measured in three different periods for the daytime measurements. In the formation of noise maps, logarithmic averages of all measurements taken at each point were used. The noise maps were overlapped with the land use maps by the help of the GIS techniques; the land use affected by the noise was analyzed.The results showed that the road traffic noise varied from summer to winter seasons in the study area depending on heavy or light traffic. The noise occurring in summer showed an increase both on weekdays and at weekends. While the limit value was exceeded in 49 of the measurement averages taken in winter, the limit value was exceeded in 96 measurements taken in summer. The noise maps formed according to the IDW method displayed that the areas in which the limit value was exceeded in the daytime in summer took up 14.27% of the study area while this rate went down to 4.06% in winter. The study area is one of the most important destinations for summer holiday. 20.12% of the area that exceeded the limit value in summer was builtup and 10.69% of them was tourism area. The noise together with population and traffic that increase in summer season is an important environmental problem against which some precautions should be taken. The findings of the study present significant results which might guide local governments in preventing and managing the noise.
