Therefore, accurate control of the acquisition time of the audio acquisition assembly 10 is achieved, the indoor audio signal acquired by the audio acquisition assembly 10 is ensured to be the audio of the outdoor audio signal subjected to sound insulation and noise reduction treatment through the glass doors and windows, and the audio which is directly conducted and acquired from the position where the glass doors and windows are not closed is not ensured, so that the data effectiveness of the audio acquisition assembly 10 is improved, and meanwhile, the power consumption of a system is reduced to a certain extent.
In a preferred embodiment, the system further comprises: a storage device configured to store a standard sound insulation coefficient of the target glass door and window; the standard sound insulation coefficient is a sound insulation coefficient obtained when the target glass door and window completes a factory test; the control device 20 further includes: installing a detection module; the installation detection module is configured to acquire an installation sound insulation coefficient when the target glass door and window is installed, and judge whether the target glass door and window is installed qualified or not according to the installation sound insulation coefficient and the standard sound insulation coefficient; the condition that the target glass door and window is judged to be installed qualified is that the ratio of the installation sound insulation coefficient to the standard sound insulation coefficient is larger than a first preset value.
It should be noted that, the glass sound insulation coefficient determination and feedback system provided in this embodiment may also evaluate the installation quality of the glass door and window.

Therefore, the installation quality of the glass door and window is evaluated by acquiring the installation sound insulation coefficient and the standard sound insulation coefficient, so that the noise reduction and sound insulation performance of the glass door and window after installation is ensured, if the installation of the target glass door and window is not qualified, namely, the ratio of the installation sound insulation coefficient to the standard sound insulation coefficient stored by the storage device is smaller than a first preset value, the target glass door and window can be immediately regulated or maintained by a responsible party after installation, the installation is not needed until the installation is finished, the installation quality of the glass door and window is monitored, the monitoring capability of the sound insulation performance of the glass door and window is improved, and the sound insulation and noise reduction use experience of the glass door and window of a user is ensured.
