For bar sound insulation treatment between private rooms, it is generally recommended to use walls made of hollow bricks or sound insulation walls made of composite damping sound insulation panels. It is best to use soundproof doors and windows for the doors and windows of the bar, and use sealing strips for sealing.

Build a light steel keel frame, make a layer of light steel keels on the original wall, first make the sky and earth keels, fix them with expansion wires, then make vertical keels on the sky and earth keels, and finally on the vertical keels. Vibration-damping keels between keels.

Fill the gaps between the keels with sound insulation material and sound insulation cotton, measure the size of the gaps between each light steel keel, and cut the rolled sound insulation cotton as needed. Fill the cut sound insulation cotton tightly into the gaps of the keel. If it is not easy to fix, you can use tape to help fix it.

Precautions for sound insulation in bar KTV:

Users need to deal with crosstalk and interference in the ducts, air conditioning ducts and exhaust ducts. The interference is particularly obvious. The firmness of the pipe installation part must be dealt with, and the sealing degree of the contact part must be considered.

A reasonable layout of speakers can reduce mutual interference. The general design is to hang the speakers in two adjacent private rooms in a back-to-back design, while reducing the back panels of the speakers from touching the wall. It is convenient for wiring and power supply, and secondly, it can also reduce sound interference.

Use heavy walls to isolate the interference from loud pressure level sound sources. Sound insulation should be done between the hall and private rooms, and between private rooms. It is generally recommended to use hollow bricks poured with cement. Soundproof walls.
