Technical Field
[0001] The present invention belongs to the technical field of rail transit noise control, and in particular relates to a method for reducing noise in urban rail transit soundscapes. Background Art
[0002] With the rapid advancement of urbanization, rail transit systems have become an indispensable infrastructure for cities. However, after they were put into operation, they also caused a series of environmental problems, mainly including vibration, noise, electromagnetic radiation and solid waste. Among them, the most prominent environmental factors are vibration and noise. The environmental vibration induced by the operation of rail transit trains will spread to the surroundings through the soil layer, and the vibration will be further transmitted to the buildings, which will cause secondary vibration and noise indoors, causing structural damage to nearby buildings, interfering with the normal operation of precision instruments, and seriously affecting the normal life of residents along the line.
[0003] At present, relevant studies have explored the negative impact of rail transit noise on citizens' health and the quality of public space. For example, rail transit noise not only affects human hearing and sleep quality, but also increases stress and affects human mental health. In addition, rail transit noise affects the ecological environment of public spaces and reduces the ecological habitat of organisms. Areas with high levels of rail transit noise pollution will reduce the willingness of residents and tourists to move around, becoming deserted and abandoned gray spaces, bringing negative psychological effects such as fear to people.
[0004] In the face of such problems, the traditional solution is to reduce the sound pressure level through noise control to improve the sound environment. However, practice has shown that due to many factors (such as psychological perception), the reduction of sound pressure level may not significantly improve the sound comfort. Therefore, the soundscape that emphasizes the listener's perception and evaluation of sound has gradually become an important concept for optimizing the urban sound environment. The International Noise Control Conference (INTER-NOISE 2008) proposed the theme of "From Silence to Harmony" and suggested shifting from noise control to soundscape research as a strategy for creating a harmonious sound environment in the city. The ISO international standard further advocates the use of soundscape design methods to create a harmonious urban sound environment by evaluating the integrity, complexity and listener response of all sounds in the environment.
[0005] In view of the special requirements of urban rail transit systems for the acoustic environment, the diversity of track forms (such as elevated, ground, underground, etc.) has put forward the need for personalized and refined adaptation of noise control and soundscape design. At present, in the environmental improvement along the rail transit system, simple noise reduction measures have limited effect, and the theory and practice of soundscape design urgently need to be further developed.
[0006] Soundscape design should not only focus on the physical reduction of noise, but also integrate visual and auditory interactive design, and provide pedestrians and residents with perceptible sound aesthetics and comfortable experience through dynamic adjustment and optimization of sound environment characteristics, so as to achieve an immersive effect. For example, interactive devices with soundscape experience can be introduced along the line, and different soundscape effects can be created by using real-time feedback of environmental noise. At the same time, soundscape design should also consider external environmental factors such as topography, climate and seasonal changes along the line to achieve organic integration with the natural landscape.
[0007] Therefore, in order to solve the impact of noise and vibration generated by urban rail transit systems on the quality of life of residents along the line, as well as the limitations of traditional noise control in improving acoustic comfort, the present invention provides a method for reducing noise in urban rail transit soundscapes.

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0039] Example 1: Reference Figure 1 , a method for reducing noise in urban rail transit soundscape, comprising: a microphone module for collecting sound environment and noise sources along the rail transit line; a processing module for processing the sound collected by the microphone module, the processing module comprising a data analysis unit, a noise control unit, a soundscape design unit, an interactive design unit, and a dynamic feedback and optimization unit; the data analysis unit is used to perform qualitative and quantitative analysis on the collected data, including analysis of sound distribution data to obtain soundscape feature information; the noise control unit is used to execute a noise control plan according to the analysis results of the data analysis unit; the soundscape design unit is used to implement multi-level soundscape intervention and design strategies, including the design of protective soundscape, transfer soundscape, augmentative soundscape and masking soundscape; the interactive design unit is used to integrate visual and auditory elements on physical noise reduction facilities such as sound barriers and soundproof walls to achieve multi-sensory design; the dynamic feedback and optimization unit is used to interact with stakeholders through real-time data collection and feedback to continuously optimize the soundscape design plan; a display module is used to display the soundscape noise reduction plan generated by the processing module;
[0040] This device conducts soundscape survey and data collection: through on-site soundscape survey, soundscape walk, questionnaire and interview and other methods, it comprehensively collects the sound environment and noise sources along the rail transit line; according to the standards of "ISO-TS-12913-2" and "ISO-TS-12913-3", it collects the distribution data of noise sources and conducts necessary qualitative and quantitative analysis to obtain soundscape characteristic information and people's perception feedback of environmental noise;
[0041] Noise control strategy based on soundscape fusion: According to different noise levels and characteristics of the areas along the line, a graded noise control plan is formulated: for areas with noise levels less than or equal to 65dBA, direct soundscape design is adopted; for areas with noise levels greater than 65dBA, physical noise reduction treatment (such as vibration reduction and sound insulation measures) is first carried out, and then the sound environment is optimized in combination with soundscape design; comprehensive measures are taken in noise source control and propagation paths, and soundscape design elements are integrated, such as local cultural background patterns, natural sound masking, etc., to improve the comprehensive effect of noise control;
[0042] Multi-level soundscape intervention and design strategy: According to the different needs of the sound environment and the population, a multi-level soundscape intervention strategy is adopted, and means such as "protective soundscape design", "transferring soundscape design", "masking soundscape design" and "incremental soundscape design" are proposed: ① Protective soundscape: retain and strengthen the natural or cultural sounds with identifiable significance in the area; ② Transferring soundscape: reduce or isolate unnecessary noise, such as physical isolation through sound barrier design. ③ Incremental soundscape: introduce sound sources that meet the characteristics of the environment (such as waterscape, bird calls, etc.) to enrich the diversity of the soundscape; ④ Masking soundscape: add natural sounds to cover up the noise of rail transit and achieve a harmonious sound environment.
[0043] Audiovisual interactive design: Based on physical noise reduction facilities such as sound barriers and soundproof walls, multi-sensory design elements that integrate vision and hearing are used. For example, dynamic displays or pattern decorations are set up on the inside of the sound barrier, and the soundscape is designed with local cultural characteristics as the theme, so that it has both good noise reduction effects and aesthetic and interactive experiences, enhancing the overall sensory experience of residents and passengers.
[0044] Dynamic feedback and optimization mechanism: Based on the continuous updating of the soundscape design brief (SDB), through real-time data collection and feedback, we maintain interaction with stakeholders (such as residents, designers, soundscape experts, etc.), and continuously optimize the soundscape design plan to ensure that it meets the actual needs of the project, environmental changes and policy requirements; after the design is implemented, the soundscape integration effect is verified through subsequent sound environment monitoring and evaluation, and adjustments and optimizations are made according to the actual results;
[0045] This is achieved through microphone modules, processing modules, and display modules. The display module displays different images to effectively reduce rail transit noise and improve the quality of the sound environment along the line through soundscape intervention and noise control measures.
[0046] Secondly, this device combines soundscape design with noise reduction to create a more attractive soundscape experience for passengers and surrounding residents, and promote the harmonious development of the environment along the rail transit line;
[0047] At the same time, cultural integration and sustainability are achieved by integrating regional culture and natural elements into the soundscape design to enhance the cultural atmosphere of the rail transit area and achieve the dual effects of noise reduction and cultural display.
[0048] Through dynamic feedback and optimization units, we ensure the continuous adaptability of soundscape design to environmental requirements and provide flexible and reliable noise control and soundscape optimization solutions.
[0049] Specifically, the microphone module may use a sensor array (such as an acoustic sensor, a vibration sensor, or a combination of an acoustic sensor and a vibration sensor) to collect physical data of the acoustic environment and the noise source;
[0050] The noise control unit automatically triggers the start and stop of the corresponding soundscape noise reduction screen through a control system (such as a PLC system or a microcontroller) according to the set noise threshold, and coordinates the work of the soundscape design elements (such as an audio playback device).
[0051] The soundscape design unit uses different soundscape design strategies to call on sound resources (such as natural sounds, cultural sounds, etc.) in the audio library and plays them through audio playback devices distributed along the route;
[0052] The interactive design unit uses the content management system (CMS) to update and manage the visual display content on the sound barrier, enables passengers and residents to interact to a certain extent (such as touch control, sensor control, etc.) through user interface (UI) and user experience (UX) design, and collects and processes user feedback;
[0053] The dynamic feedback and optimization unit continuously collects acoustic environment data through the microphone module, feeds back the data to stakeholders (such as residents, designers, soundscape experts, etc.) through a network platform (such as a web page or mobile application), collects their opinions and suggestions, uses this feedback information to update the soundscape design outline through an optimization algorithm, and feeds back the optimization results to the processing module.
[0054] This device is used in rail transit stations (such as shielding doors, ceilings, curtain walls, etc.), outside of track sound shielding barriers, or other scenes where noise reduction is required, without limiting the specific usage scenarios.

[0056] The LED transparent display screen 10 is installed on the first glass 1 or the second glass 11. Since the LED transparent display screen 10 is transparent when not displaying images, there will be no shading problem.
[0057] When the processing module transmits the soundscape noise reduction image to the LED transparent display screen 10, the LED transparent display screen 10 will display the image and can produce sound in conjunction with the speaker, thereby using the image and auxiliary sound to interfere with and attract the vision and achieve the effect of noise reduction.

The honeycomb noise reduction portion 13 is made of a transparent material, such as glass or plastic, thereby reducing the obstruction of the first glass 1, the second glass 11, and the LED transparent display screen 10.

[0063] The honeycomb noise reduction part 13 is connected in a lateral position through the connecting groove 131, so that the noise can be absorbed through more reflections in the honeycomb noise reduction part 13, so that the physical noise reduction effect is better, and then used in conjunction with the display module to achieve a better noise reduction effect.
[0064] Example 4: Reference Figure 5 , an urban rail transit soundscape noise reduction device, which is basically the same as Example 2, further comprising: a connecting groove 131 is provided on the three reflective inner wall layers 132 of the honeycomb transparent interlayer;

[0067] The six reflective inner wall layers 132 are opened, which makes the physical noise reduction effect better, and the number of noise reflections in the honeycomb noise reduction part 13 is further increased, thereby improving the noise reduction effect.
