What if the window beeps when it is windy?

The noise from a windy window indicates that the window is not sealed properly. First, check the air leakage of the underground door. Where it can be sealed, you can go to the hardware local product store and buy a bucket of sealant to seal it.

Some places can't be changed, such as the sliding window itself is not well sealed. There are also inferior broken bridge aluminum windows with poor sealing performance.

If you want to solve it completely, you can change it to one with good quality and better heat and sound insulation if you have the conditions.
