    A case study for implementation of the classification scheme introduced in the new sound insulation regulation in Turkey
    (Institute of Noise Control Engineering, 2017) Şentop, A.; Tamer Bayazit, N.; Kurra, S.; Demir, D.
    The "Regulation on Protection of Buildings against Noise" issued by the Turkish Ministry of Environment and Urbanization, in May 2017, aims to organize the requirements and enforcements for noise control in buildings. The regulation introduces a classification scheme to rate acoustic performances of buildings based on the EU/COST TU 0901 project and ISO-CD19488, and the verification tests in order to obtain "Acoustic Performance Certificate" which is a legal document authenticating the acoustical quality of the building. As an application of the regulation, a residential building was selected for the case study and the airborne sound insulation of partitions and façades, impact sound insulation of floors, reverberation times of common areas and indoor background noise levels were measured to evaluate the acoustic performance of the building and to determine its acoustic class. Based on the results, the applicability of the limit values given in the regulation could be checked. In the study, a pilot social survey was conducted to investigate the responses of the residents against variety of indoor and outdoor noises. The preliminary results have supported that Class C, which is also a requirement for new buildings in the regulation, was satisfactory for most of the residents in the building. © 2017 Institute of Noise Control Engineering.

    Noise control by design: A tool intended for architectural use
    (Australian Acoustical Society, 2014) Sentop, A.; Tamer Bayazit, N.; Altun, M.C.
    This study aims to present a building elements selection tool, which has been generated to assist architects with determination of acoustically appropriate assemblies at the preliminary design stage. In order to succeed, practicality, easy usage and reliability are considered essential for every step. In this context a catalogue and a calculator are generated as components of the tool. The catalogue constitutes a database in which building elements are subcategorized according to their constructional and acoustical characteristics. Acoustical measurement results of 587 different assemblies are collected from relevant literature and their technical drawings are prepared in order to provide easy selection. The calculator serves to simplify the calculations by giving the sound insulation requirement according to outdoor noise levels and acceptable background noise levels. The calculator also determines composite (average) sound insulation value of building elements composed of multiple components. Background noise criteria and data from the catalogue are predefined in the calculator, simplifying data insertion and parallel usage of the catalogue and the calculator. In order to prove efficiency and practicality of the building elements selection tool, its usability by architects is tested on subjects with a sample design problem and outcomes are discussed.

    Proposed methodology for new regulation and guidelines on noise protection for buildings and sound insulation in Turkey
    (German Acoustical Society (DEGA), 2016) Tamer Bayazit, N.; Kurra, S.; Şan Özbilen, B.; Şentop, A.
    The draft regulation prepared for the Turkish Ministry of Environment and Urbanization, aims to organize the requirements and enforcement for noise control in buildings. A model describing an ideal framework of a building acoustics regulation was introduced and implemented during preparation of legislative and technical documents. The new regulation covers acoustical design, evaluation of acoustic performance during construction, supervising and certification of acoustic quality, investigating and elaboration of complaints from existing buildings. New rating descriptors and the basic classification scheme for the residential buildings were adopted from COST TU 0901 project, however the acoustic performance of buildings in terms of indoor limits, reverberation times, mechanical noise limits and required insulation values, were evaluated for all types of buildings and indoor spaces according to the criteria assessment model developed in the study. Special concerns were given into consultancy, training and building supervising. A technical document prepared to complement the regulation, describes the implementation process of the regulation and highlights good design practice considering the state-of-art in building sector in Turkey. A "decision- model" for low-rise houses is proposed based on the present data for the building elements. This paper summarizes overall results of the study conducted in Istanbul Technical University. © 2016, German Acoustical Society (DEGA). All rights reserved.
