Of course, if the gym window is soundproof, sealing is the most important thing. The sound insulation system of the whole room is like the bearing capacity of a wooden barrel, which is determined by the shortest sawdust, and the sound insulation effect of the room is determined by the weakest window. No matter how we choose to do window sound insulation, we can't help but pay attention to ventilation. If the indoor environment is too closed, it will do harm to human body and be harmful to health. Therefore, we should not only pay attention to sound insulation, but also pay attention to ventilation requirements.

The concrete walls on both sides of the gym wall are used for sound insulation. The partition wall is generally built to the top, so pay attention to the sealing of the pipeline to avoid crosstalk. The sound insulation board is a professional sound insulation material, with metal plates on both sides and sound insulation foam plastic in the middle. Of course, the greater the thickness of wallboard, the better the sound insulation effect will be.

Gym can choose some heavy curtains and carpets, which can effectively reduce indoor noise. With the experimental surface, the sound absorption effect of vertically placed and tiled fabrics is the same. Thick fabrics will have much better sound absorption effect than thin fabrics. The more cotton wool in the carpet, the better the effect. The floor and ceiling can also be soundproof. A mat that can be installed on the floor. The ceiling can be added with soundproof ceiling, sometimes called fake ceiling or ceiling.

A broadband muffler can be installed at the exit of the gym. Air conditioners and exhaust ports will produce noise during the discharge process. It is necessary to install a compound muffler to basically eliminate the low-broadband sound waves in the muffler without affecting the normal exhaust. It can also achieve the effect of silencing.
