How to do the sound insulation treatment? The house is on the side of the road, the noise is too loud and I can't sleep well.

Our family can't stand this noise when they sleep. When we were decorating, we studied many sound insulation methods. Let me talk about my experience. First of all, the window, it is recommended to install that kind of hollow sound insulation window, on the one hand, the sound insulation effect is good, on the other hand, it is also heat-resistant and cold-resistant. Secondly, some efforts can be made on the wall. At that time, we saw a soundproof putty in the offline Nippon store, called the batch of Lebao soundproof leveling lightweight gypsum. Strong adhesion, can be brushed into a sound insulation wall. This putty also has a certain function of heat preservation and humidity adjustment, which is more suitable for the climate in the south. Finally, there is another insurance, that is, our family chose thick curtains with sound insulation effect, which is foolproof. I can hardly feel the noise now. I hope it helps you.
