As a result of rapid changes in developing countries; unplanned and intertwined development of residential and industrial areas, uncontrolled population and related traffic density increases, new transportation systems implemented without determining the negative effects on the environment and infrastructure inadequacies, noise has become increasingly important and has become an environmental problem that seriously affects human health. Noise must be controlled to create an auditory comfortable environment. TUBITAK Marmara Research Center (MAM) Environment and Cleaner Production Institute (ÇTÜE) carries out studies on Noise Management for the detection and solution of the effects of environmental noise.

Strategic Noise Maps are being designed to evaluate the noise impacts emitted from different sources within a given area as a whole or to evaluate such an area by taking into account all sources and physical environmental factors. With the Strategic Noise Maps prepared by TÜBİTAK MAM ÇTÜE;

• "Noise Dispersion Model" and "Spatial Noise Database" is being created,
• Sensitive areas affected by noise sources are identified,
• Level-dependent exposure percentages of the affected population are determined.

Strategic Noise Maps have been prepared for 39 provinces in Turkey under the coordination of the Ministry of Environment and Urbanization and with the support of municipalities; studies are ongoing for 20 provinces. In 59 provinces, inventory infrastructure for source-based noise modeling has been established. In addition, Strategic Noise Maps of 47 airports have been prepared.

We are creating "Noise Mitigation Scenarios" and "Noise Action Plans" for the hotspots identified in the Strategic Noise Map outputs. Within the scope of these studies, by TÜBİTAK MAM MTUE;

• The noise problem is defined in all its aspects on a regional scale,
• Solution proposals are being developed in settlements exceeding the limit values,
• Noise control measures necessary for the protection of quiet areas are identified,
• Current situation analysis and recommendations are produced in city growth and transportation planning.

Noise Action Plans have been prepared for 6 provinces (Mersin, Sivas, Antalya, Bolu, Kahramanmaraş and Trabzon), and work is ongoing in 5 provinces (Ankara, Denizli, Kütahya, Uşak and Malatya).

TÜBİTAK MAM ÇTÜE also carries out "Development of Domestic Noise Barrier Systems" studies within the scope of the needs in the provinces where current situation analyses have been completed. For the first time in Turkey, Domestic Glass Fiber Reinforced Concrete Noise Barrier Systems (Glass Fiber Reinforced Shell Concrete Noise Barrier System and Glass Fiber Reinforced Foam Concrete Filled Noise Barrier System) were developed to control environmental noise.

Two different Noise Barrier Systems were developed with the "FIBROBETON Noise Barrier System Acoustic Design and Applications Project". These two products developed and commercialized at the same time;

• Lower cost compared to foreign counterparts,
• Easier availability,
• Compliance with national/international standards,
• Compliance with the General Technical Specification for Noise Barrier Works has the basic features.

These products are planned to be used on highway and railroad edges, garden borders of sensitive structures such as schools, hospitals, etc., and around industrial and entertainment facilities.

TÜBİTAK MAM ÇTÜE is the only accredited institution in Turkey that can determine the field performance values of noise barrier systems. The parameters that can be determined within the scope of field tests of highway and railway noise barriers can be listed as sound absorption coefficients, sound transmission loss values, sound diffraction values, road surface sound absorption coefficient.

It is the only accredited laboratory in our country with the infrastructure to make measurements in accordance with TS EN 1793-4, TS EN 1793-5, TS EN 1793-6, TS EN 16272-4, TSE CEN/TS 16272-5, TS EN 16272-6 and DIN ISO 13472-1 standards.
