MEASURES TO BE TAKEN TO REDUCE NOISE
- Establishment of airports, industrial and industrial areas away from residential areas,
- Preventing unnecessary horns of motor vehicles,
- Preventing the sound level of musical instruments that are raised electronically in public places and residential areas to be disturbing the environment or prohibiting such activities in residential areas,
- Minimizing the noise level to be exposed to employees in the workplaces, (evaluated under the Bakanlığı Noise Regulation Bakanlığı of the Ministry of Labor and Social Security.)
- Providing sound insulation in newly constructed structures in order to prevent noise disturbance in residential areas and buildings,
- Noises of radio, television and musical instruments are disturbed in the settlements and residences.
- Public transport rather than individual driving to reduce traffic noise, (This will also contribute to the reduction of air pollution.)
- Sound insulation should be provided in motor vehicles, especially mufflers should be used in small motor bike type vehicles.
There are certain measures that can be taken to prevent noise-related discomfort and health-related harm. These measures are applicable if the values in the tables specified in the regulation are exceeded. There are a number of technical, construction and workplace protection measures. In fact, the noise element should also be considered in urban planning and in the selection of industrial settlements. As with all environmental pollution factors, the most appropriate solution is to prevent noise at the source. But this is not always possible economically and technically. The technical and organized measures that can be applied to reduce noise are listed below.
Depending on the situation in your business and the framework, one or more combinations can be applied. The efforts to combat noise and reduce the negative impacts of noise levels on the environment can be prevented by joint efforts of public institutions and non-governmental organizations. Again, the institutions authorized by the regulation should do their part completely in order to comply with the restrictions and prohibitions introduced in the regulation. Non-governmental organizations should inform the public and ensure communication and control between public institutions and the public. More regular zoning plans should be made especially in municipalities that create new urban areas.
In order to reduce the traffic noise, increasing the distances between the houses and roads and making greening works should be the first priority. On very dense roads (highway, ring road), screening works that do not create image pollution are required. Within the scope of the zoning plans, it is necessary to make the necessary insulation in accordance with TSE standards between the flats and the houses and the outdoor environments in the new houses. In these dwellings, it should be inspected by the authorized institutions whether the insulation procedures are in TSE standards and after the necessary measurements, resettlement should be given. The distance between the road and the receiver is foreseen to be 30-40 m in order to achieve a significant noise reduction. In general, increasing the distance between the receiver and the road 2 times, depending on the distance can be said to provide a 3 dBA reduction.
On the other hand, she was obliged to make sheathing in the houses. At the end of a certain period, the building will not be left without jacketing. This system will prevent the loss of energy as well as reduce the noise. Noise caused by noise increases as vehicle speed increases, which is one of the important factors affecting the disturbance level in the receiver. A vehicle driving at a speed of 32 km / h at a distance of 30.5 m from a road approximately at the same elevation as the surrounding terrain creates a noise of 50 dBA, while a vehicle with a speed of 64 km / h creates a noise of 58 dBA. The increased traffic volume along with the speed of the vehicle increases the noise felt at the receiver. In addition to effects such as speed and number of vehicles, low or high road affects the noise level. The further away you are from a road below according to the surrounding terrain, the less the noise. It is observed that the noise level decreases between 50-10 dBA when the sections of the road are cut and crossed. The fill level should be higher than 2.5 m in order to be effective in reducing noise. On surfaces where the road is covered with a smooth covering layer, noise is less than normal asphalt or concrete surface. The steepness of the road slope is particularly important due to the increased noise generated by heavy vehicles when climbing steep slopes.
