How to decorate and reduce noise

1. In the process of replacing old cotton cloth, the tools used are heavy hammers, impact drills and other machinery, which makes a lot of noise. The construction period is as short as 3 or 4 days and as long as one week. During construction, the machine can be wrapped with old cotton cloth to reduce the noise generated when the machine rotates. Spreading old cotton cloth on the ground can reduce the spread of noise, and the impact sound of removed wall tiles falling on the cotton cloth will also be reduced.

2, doors and windows, closing doors and windows during decoration can effectively reduce the spread of noise. At the same time, the choice of doors and windows is also skillful. Windows are soundproof and doors are fireproof and soundproof. It can not only reduce the decoration noise, but also be more secure in future use.

3, walls, smooth walls look beautiful, but the effect of noise reduction is very poor. The rough wall can make the sound turn irregularly many times, which can effectively reduce the noise. For example, large spaces such as cinemas and churches are prone to echo, and rough walls can just solve this problem.

Each door has a certain sound insulation effect, but the effect is very different. Whether the door partition is soundproof is not only the sealing performance after the door is closed, but also the quality of the door panel. The sound insulation effect of the door panel mainly depends on the filler in the door core. Generally speaking, the inner core of molded sound-proof door is filled with paper base with honeycomb structure, and the closed air layer formed by it can play a good sound-proof role. The inferior door panel, however, only has a few rough partitions in the hollow with cardboard, and the sound insulation effect is very poor.
