NOISE CONTROL IN RESIDENTIAL BUILDINGS IN THE CONTEXT OF NATIONAL REGULATION AND AN EXAMPLE

Abstract

Noise in residential buildings has been a problem for users for years. In order to ensure acoustic comfort conditions in these units, noise control is included in the country's regulations. As a result of noise control gaining importance in our country in recent years, the Regulation on the Protection of Buildings Against Noise (2017) and the Regulation on Amending the Regulation on the Protection of Buildings Against Noise (2018) came into force. In this context, the aim of the study is to examine the noise control of an existing residential building and present suggestions for improvement by comparing it with the limit values defined in the regulation. Using the Insul (v9.0.24) simulation program, calculations were made to produce an evaluation of an independent unit of an existing residential structure. According to the results of this study, it has been determined that the sound transmission loss is quite high in the external walls of the composite structure due to the high wall thickness and the use of double-layered structural elements, but the insulation value of the composite system decreases due to the low sound transmission loss of the windows. While sufficient sound insulation is provided in the interior walls, it has been determined that the impact sound limit values are not met due to the lack of adequate sound insulation measures in the floors, as in many residential buildings. For this reason, in the study, suggestions are presented to improve the sound insulation values of building elements that do not meet the limit values.
