Description

1 TARIFF ROAD NOISE MEASUREMENT SYSTEM TECHNICAL FIELD The invention is used in determining noise maps of highways and municipal roads, sound 5 in determining the height of the barriers and the sound propagation across the cross-section a road noise measurement system to be used in modeling the distribution It is related. PREVIOUS TECHNIQUE 10 The current application used to measure highway noise has several features. It has many shortcomings. The deficiencies of the current approach are listed below. They are listed in bullet points. 1. For use in noise maps and / or noise action plans, a 15-meter-long beam perpendicular to the road axis. noise data is collected only at a specific point: The horizontal line marked by the authorized person taking the measurement, starting from the edge of the road platform. The current method is applied by placing the measurement station at the point in the distance. The process begins. After the tripod is set up at the designated measurement point... The installation of the noise measuring device on the station is proceeding. Noise measurement 20 The devices are placed in the ear at a height of approximately 1.2-1.5 meters above ground level. It is positioned on the tripod so that it is aligned. All fixing is done in place. After the completion of the works, the road will operate within the initially determined timeframes. The noise is being recorded, and all the noise data obtained is being fed into the relevant software. Noise 25, defined and showing the road-related noise exposure values ​​of the region. Maps are being created. This current application captures sound waves in different horizontal and vertical directions. It cannot determine how it behaves at different distances. Only from the road axis. a single horizontal distance apart and a single vertical distance above ground level Maps created by taking into account the collected data, sound in the study area Because the recorded data did not allow for accurate modeling of the spread, 30 Noise reduction efforts undertaken in light of this situation are incorrect and inadequate. 2 2. Sound transmission standards: Studies on sound propagation in the literature show that the sound originating at the source... It is assumed that the wave propagates linearly in a linear pattern. However It is also possible that the propagation, which is considered linear, may actually be parabolic or hyperbolic. This has been demonstrated by preliminary data from studies conducted by the inventors. Also, 5 The question of what constitutes the aforementioned sound propagation angle and intensity is not fully explained in the relevant publications. It is not stated as such. 3. Residential living spaces are generally at least 3 meters above ground level: Considering daily life, the places where people spend the most time are the top 10. It is inevitable that the areas where they need the most rest are the homes where they live. That's true. When we look at the locations of these settlements, they are generally gallery floors. It has been observed that the noise starts above the building entrances. The current noise level is... In the measurement methods, the measured exposure values ​​are at a distance of 1.2-1.5 meters from ground level. It occurs at a certain height. However, considering the proposition given at the beginning, 15 These noise recordings were made outside the areas that most affect people. This is observed. This means that the measured road noise is the level at which people most desire silence. This proves that it does not reflect the living spaces they need. Apart from residential buildings, other building types are considered in terms of noise sensitivity. When this is taken into consideration, public and hospital buildings also suffer from this inadequate measurement method. It can be observed that it is affected. Schools, regional directorates, provincial headquarters and hospitals, etc. Considering the existing structures, the measurements taken were 1.2-1.5 meters high. It appears that these areas are on the ground floor. Ground floors are generally where citizens make their initial applications. It has qualitative equipment that includes guidance instructions. The main processes are 25. The areas where this is carried out and where employees spend a large portion of their time are included in this introduction. It occurs above the floors. This also means that the current noise measurement is mentioned at the beginning. This shows that the methods used were inadequate and incorrect. 4. Standardization of sound barrier heights: 30 Noise used to reduce the environmental impact of road noise. Barriers differ according to the type of material they are made from. Hollow brick, Noise barriers are manufactured using a wide variety of materials such as polycarbonate, wood, and steel. However, considering the types of noise barriers used in the market... 3 While there are differences in building materials, the movement of noise propagation... It appears that no type analysis has been conducted taking into account all noise waves. The assumption that they exhibit similar distribution has prevented research from being conducted in this area. However, the proposed new method for measuring road noise does not measure the sound generated by vehicles. The waves exist in different forms, therefore there are 5 different types of waves on noise barriers. It has shown that different geometric properties need to be introduced to the types. Furthermore, the existing Considering noise barrier specifications and application principles, noise How many meters horizontally should the barrier be positioned from the roadside? It has also been observed that there is no quantitative data to support the need for such a measure. 5. Unconsidered effects of noise: Although the term noise is a term that has formed around human perception... the negative impact of noise on the ecological environment is becoming increasingly apparent every day. It is growing into a situation that cannot be ignored. Bird migration routes and Many living habitats, such as fish breeding grounds, are exposed to the effects of noise. 15 Although all of this does not currently have a direct impact on human life... If precautions are not taken, there will be a clear risk to human health in the future. It poses a risk. Therefore, preventing environmental noise is important for all living beings. It should be considered a necessity, not just a need. However, the current noise being made... This effect is ignored in studies. 20 6. Taking measurements with a noise measuring device: The current noise data collection efforts involve one noise measurement unit. This is carried out using a device. Noise measurements are taken at certain intervals before each measurement. Even though the devices were calibrated, an unforeseen 25 occurred during the measurement. any other device that can form a control group in case of malfunction It is not used for this purpose. This means that noise measurements made with 1 device are not realistic. that it will create a risk and cause inconsistent results It shows. THE PURPOSE OF THE INVENTION In measuring road noise, the guidelines specified in the previous Technical section should be followed. In order to resolve the issue caused by the application of existing methods, noise... New discoveries have been made regarding measurement systems. 4 The method applied using the measurement system described below shall be followed. The drawbacks of the current method described in the previous Technical section are as follows: This is how it is resolved. The invention involves the same source at 9 different coordinates for 3 different levels and 3 different distances. Noise measurement involves noise measuring devices located at 9 different coordinates, all at the same time. It is based on the principle of recording source noise. Each recording is unique in itself. Upon examination, it was found that a single noise source or equivalent noise values ​​were in the same direction. This allows for the modeling of the effect it will create. Thus, in the source This shows how the noise generated will spread horizontally and vertically across the cross-section. It is possible to determine what noise levels are generated as a result of the propagation. This is 10 It provides solutions to the problems numbered 1, 2, and 5. Measurements are taken at three different adjustable elevation values, 3 meters from ground level. and argues that measurements should be taken at heights of 4 meters. Furthermore, single Taking measurements at these levels will not be sufficient, therefore we will follow the highest level. It emphasizes that the measurement points should be determined at both lower levels. 15 Thus, the noise level that a sound wave would create at a height of 3 to 4 meters is... can be determined and the effect caused by sound as it travels vertically. Exposure change can also be calculated. All of this is possible with the current methods. It provides solutions to issues 3 and 4, which are among the problems. Data collection using 9 noise measuring devices of the same type, 20 while collecting noise data. Simultaneous recording of data from nine noise measuring devices of the same model and type. The aim is to prevent any problems from occurring on any device while data is being collected. the negative impact that will occur in this situation due to other devices continuing to record It reduces the need for multiple devices to record simultaneously. Also, using multiple devices allows all devices to record at the same time. The advantage in terms of comparing the consistency of the data obtained is 25. This provides a new method proposed that is superior to the previous technique mentioned in point 6. It eliminates the disadvantage it creates. LIST OF FIGURES Figure 1.

DETAILED DESCRIPTION OF THE INVENTION The invention accurately determines the area of ​​impact of traffic noise on any road. It is related to a measurement system aimed at determining it in some way. On the highway (X) to be examined, there are multiple points on the same line. Thanks to the system and method described in the invention, which envisages taking measurements, 20 meters can be taken along the roadside. The noise emissions generated can be accurately modeled. The system, on the road... The first horizontal line will be five meters horizontally from the edge of the platform. The first measurement station (1İ) will be located at a distance (Y1) from each other, and they will be equal and identical. It includes three measurement stations arranged horizontally in the direction of the second horizontal line. 2nd measurement station (2İ) at distance (Y2); 3rd measurement station (Y3) at horizontal distance 25 (3İ) are located. They are equidistant from each other (The distance between them is 10, 13, 15 meters (It is possible) these three stations (1I, 2I, 3I) are positioned perpendicular to the road. Each station will correspond to three different elevation values ​​(0.20, 1.20, 3.20). It is marked as shown. Noise levels (elevation values) of 30 are recorded at each measurement station (1I, 2I, 3I). There is a measuring device. 1.

(2B, 3B) is also at the very bottom, above the other measurement stations (2İ, 3İ). Noise measuring devices are located in the middle (2M, 3M) and at the very top (2T, 3T). 6 Noise measuring devices and microphones at each marking point (measurement station) The section is fixed perpendicular to the road. Thus, three different sections are aligned horizontally with the road axis. The noise levels of each measurement station (1I, 2I, 3I) located at a distance from each other in the vertical direction. Measuring devices (1B, 1M, 1T, 2B, 2M, 2T, 3B, 3M, 3T) taking measurements in the same direction. It is ready to use. 5 After all the installation procedures are completed, the same type of noise measuring devices are used to test the noise level in the field. The collected noise data is processed by mapping software to determine the noise levels around the highway. Noise exposure values ​​are determined more accurately here. The specified software can be found in any electronic device capable of running software. They can be found. Thus, at horizontal and vertical distances different from the road axis, 10 The measurements to be taken will accurately determine the noise levels that will occur around the highway. Modeling is provided. During the initial setup phase of the system, noise data collection studies were conducted. 9 noise measuring devices of the same make and model, and these noise measuring devices... Three mounting poles strong enough to support three of the devices are supplied. 15 Next, the noise impact area is to be determined from the end of the platform edge of the road where the noise impact area is to be defined. The locations of three measurement stations at equal distances are determined (Y1, Y2, Y3). For each of the determined stations... Measurement stations supplied for point measurement are placed (1I, 2I, 3I). Subsequently noise measuring devices for different elevation values ​​determined on the station They are mounted on poles (1B, 1M, 1T, 2B, 2M, 2T, 3B, 3M, 3T). All devices are 20 After the stabilization process is complete, noise data collection begins and the software... Measurements by each noise measuring device (1B, 1M, 1T, 2B, 2M, 2T, 3B, 3M, 3T) The values ​​recorded throughout the period are compiled into a general table. Finally... Noise data obtained as a result of the measurement study can be used to create a noise map. The noise generated around the examined path (X) is processed by the generation software. 25 Exposure values ​​are visualized.
