Objective: To evaluate the quality of sound environment in different areas of sound environment, and to understand the temporal and spatial distribution characteristics of environmental noise in functional areas.            

Fixed-point monitoring method: select 1 to several monitoring points that can reflect the quality characteristics of various functional areas, and carry out long-term fixed-point monitoring. The position and height of each measurement should remain unchanged. For the 0, 1, 2, and 3 types of sound environmental functional areas, the monitoring point should be the possible maximum value of the vertical distribution of the sound field in the outdoors for a long time, and the position should be able to avoid the fixed noise source of the reflector and the nearby, and the 4 types of sound environmental function area monitoring points are located in the first row of the noise sensitive buildings in the 4 types of areas. The possible maximum value of the vertical distribution of the noise space. So our company has the following French professional simulation software:

● Architectural acoustics simulation software: Based on the overall shape of the building, materials, it can accurately predict indoor - indoor, outdoor - indoor, upstairs - downstairs air transmission noise, knocking noise and equipment noise simulation values.

● Theater acoustics simulation software: mainly for each seat acoustic simulation, reverberation time and sound direction simulation.

● (E) environmental impact assessment software: by simulating building shape, decibel, road laying, river flow path and so on, the noise value of surrounding environment is comprehensively simulated.
