Then, the measurement data in the testing was analyzed to find the influence of the open mode, the type of material section, glass thickness, and traffic noise spectrum on the insulating performance. Finally, some qualified doors and windows were taken as examples to show how to check up the products and determine their sound insulating performances through in-situ testing.
