A Study Comparing the Noise Reduction Behavior of Variously Shaped Barriers of Limited Size in Indoor Spaces

Abstract

The noise produced by machines in the factories of industrial facilities have negative effect on both physical and mental health of the workers. For this reason, in such factories, it is necessary that machines, which produce considerable noise be situated together in an area and separated from the sections of the facility that produce less noise. This study investigated the noise reduction values of multi-layered planar, L-shaped, and U-shaped barriers that were used to separate the sections with machines producing a high level of noise from the people working in the sections where the machines produce less noise. Given the shapes, the dimensions and the distances of the barriers to the receivers and also considering the differences in unit weights, this study has analysed the noise reduction values of various barriers through measurement; compared and evaluated the findings; and made further recommendations.

A Method of Multi-Attribute Assessment Using Ideal Alternative: Choosing an Apartment With Optimal Indoor Environment

“…the paper (Bluyssen, 2008) presents contribution of pollutants from different structures (floor, walls, and ceiling) to indoor air concentration levels during the first year after the building was taken into use. Kavraz and Abdulrahimov (2009) analyse an importance of noise reduction for goodness of indoor being. other pollutants and attributes of indoor environment, like dust (latif et al, 2009), nitrogen oxides (Vilcekova and Senitkova, 2009), energy saving (yik and lun, 2010), toxic moulds (Singh et al, 2010), lighting installations (Boyce, 2010), housing environment (Braubach, 2007), thermal environment (cheong et al, 2006; gulyas et al, 2006), etc.…”
