when installing important facilities, such as when installing door and window, the model and the kind of door and window, the closely degree of being connected between door and window and the wall body, the laminating degree between window and the window frame etc. all can direct determine the size after external noise gets into indoor, and door and window's installation and selection still influence indoor ventilation condition, also will influence indoor air quality. In the construction process, an analog noise source is installed at an appropriate outdoor position, a worker firstly places a door and window at a position needing to be installed, if the joint of the door and window is not tight, the noise value detected by the system in the room is larger, the worker needs to adjust the installation position of the door and window, in the adjustment process, when the worker sees that the noise value detected by the system in the room is lower than a set value, the installation position meets the requirement, and then the door and window are kept motionless and fixed.
Similarly, the decoration of other locations such as indoor roofs, walls and floors can also have a common impact on the indoor noise (mainly noise generated by upstairs and downstairs and neighboring households and transmitted into the indoor) and the air quality. Since many of the existing decorative materials in the market at present emit harmful substances during use, as long as the content of the indoor harmful substances does not exceed the relevant prescribed critical value, no harm is basically caused to the health of households, and the emitted harmful substances gradually decrease over time. During actual construction, the indoor roof, the wall body and the floor are firstly paved according to the installation positions and kept still for a certain time, during the period, the indoor air quality is monitored by the monitoring system provided by the invention, if the content of harmful substances exceeds the standard, the indoor air quality is negotiated with a customer in advance, the problem that the harmful substances cause larger trouble is avoided, and if the content of the harmful substances meets the requirements, the next installation operation is carried out. The system is also adopted to monitor the indoor air quality in real time in the installation process, so that the content of harmful substances exceeds the standard due to construction is avoided. Meanwhile, an analog noise source can be installed at an appropriate outdoor position, and a worker can determine whether the installation positions of decorative materials such as a suspended ceiling and a floor are in place or not through the indoor noise size monitored by the system.
The plurality of monitoring devices 4 may be arranged according to an actual room space structure, for example, for a common cuboid room, usually 9 monitoring devices 4 are arranged, one for each of eight corners of the room, and one for the center of the room.
