Effect of mass housing settlement type on the comfortable open areas in terms of noise

Abstract

The layout of the structures according to the noise source is an important parameter in terms of the level of noise reaching to both open usage areas and the structure surfaces. In this paper, it is aimed to reveal the effect of mass housing settlement type on the size of suitable open usage areas in terms of noise. Comfortable open usage areas in 25 mass housing alternatives are determined for the case of being affected by three different road noises. The reliability of the simulation results is validated by on-site noise level measurements. As a result, it is seen that better results are obtained in linear, L, C, and U type alternatives than point-type blocks. Especially in alternatives consisting of point-and linear-type blocks, if the noise level is above 75 Leq (dBA), the percentage of comfortable open usage areas is very low. It is determined that the percentage of comfortable open areas increases between 50 and 100% by means of appropriately designed noise barriers.

An approach to the design of photovoltaic noise barriers and a case study from Istanbul, Turkey

“…Environmental parameters (site topography, forms, and dimensions of the buildings, types of ground surfaces) and tra c data (vehicle volume, vehicle speed, heavy vehicle rate, etc) should be de ned in the simulation software most accurately to represent real data in the noise maps. As proved by various studies in the literature, when the inputs are detailed and accurate, SoundPLAN 7.2 software performs consistently with a higher accuracy (Akdağ et al 2017; Guedes, Bertoli, and Zannin 2011; King and Rice 2009). Figure 3 reveals the current noise climate of the case study area.…”

“…However, the ANNEX 1 of the same directive states that other heights may be chosen for design local measures, provided that the minimum height above ground should be 1.5m. Since this study evaluates the acoustic attenuation in open areas, assessment point height was accepted as 1,5m, the average height of the ear level (standing) (Akdağ et al 2017).…”

Seeking the Nexus Between Building Acoustics and Urban Form: A Systematic Review

“…Some studies conducted a mixed-methods approach on the last category (facade and building acoustics). Akdag et al [ 43 ] evaluated 25 mass housing structures and their facades within different road types. They both used simulation and on-situ sound sampling techniques on linear type blocks facades and reported the highest noise levels while open spaces showing the lowest.…”
