Do you also dream of inviting a bunch of friends to sing at home, but are often complained by neighbors? Some people are confused. I have already used the best soundproofing materials. Why do neighbors still often come to the door for trouble? Because You only achieved sound insulation and forgot to reduce vibration. If we turn on some low-frequency speakers, objects will also resonate, such as water on the table will start to produce ripples.

A large part of sound insulation is related to the decoration materials, let's focus on how to reduce vibration.

With several speakers, there are several point sound sources and several spherical sound waves. In terms of the transmission path, the speaker can transmit sound waves to all places through suspension rods, top beams, columns, walls, sewer pipes, doors and windows, and exhaust ports. Located in the middle or bottom of residential buildings, especially high-rise buildings, it is very difficult to control. The necessary vibration and sound insulation must be implemented from all points and surfaces to achieve the design requirements.

1. Install speaker vibration dampers or damping hooks. Speakers are usually placed on the ground or suspended around beams. When playing strong music, the speakers impact the ground, beams, columns, or floor slabs in resonance with the frequency of the music, and then transmit elastic waves to the residential rooms upstairs in the form of solid-borne sound. Therefore, it is necessary to adopt the form of paving the vibration reduction system and adding vibration reduction hooks to isolate the vibration of the point sound source from the building connection point.

2. Additional vibration damping layer and sound insulation layer are added to beams, columns and floor slabs. After the sound waves of the speakers are emitted, the sound waves generate high-energy vibrations in the air, which impacts the walls, columns, beams, and floor slabs one by one. The low-frequency part can penetrate the concrete wall and quickly upload to the residents' indoors. Therefore, it is necessary to add elastic surface layers or sound-absorbing hollow resonance layers to the main beams, main columns and floor slabs to eliminate the impact of high-energy sound waves on the main beams, main columns and floor slabs.

3. Add damping layer and sound insulation layer to fire fighting pipeline and sewer pipeline. The sewer pipes of high-rise buildings are generally concentrated on the bottom layer, and sound waves can be transmitted directly to each household through the thin wall of the water pipe. Therefore, each sewer pipe connected to the upper floor must be re-wrapped, with a vibration damping layer on the inner layer and a damping layer on the outer layer. In the sound insulation layer, a soft connection must be added in the middle.
