What is the difference between sound-absorbing sponge and sound-proofing sponge

What is the difference between sound-absorbing sponge and sound-proofing sponge

It sounds like sound-absorbing sponge and sound-insulating sponge are both used to reduce noise, but few people know what is the difference between the two. Today, let the editor of the sponge product manufacturer tell you about the difference between sound-absorbing sponge and sound-insulating sponge. what a difference.

*sound absorbing sponge*

Sound-absorbing sponge is a kind of solution to reduce noise with very sophisticated technology and low cost. It is formed by high pressure molding of sponge. It is used in recording studios, conference halls, KTV and other places. With the increasing expectations of people for a comfortable living environment, sound-absorbing sponges have begun to enter the home. As a subordinate solution to the wall, it can meet your needs for creating a quiet environment, and it also has a certain degree of ventilation.

Sound absorption principle:

The sound-absorbing sponge achieves noise reduction and sound absorption through the back and forth reflection of sound waves in the sponge. It is understood that when the laying area is greater than 3 square meters, it can achieve excellent sound absorption and sound insulation.

Defects of sound-absorbing sponges

The sound-absorbing sponge itself is likely to accumulate dust, and the low-quality sound-absorbing sponge has excessive formaldehyde content or is rich in other pollutants. Please pay attention to selecting qualified products.

Suggestion: leave the sound-absorbing sponge to professionals

Sound-absorbing sponges are usually 20mm-90mm thick, and industrial products are usually 1m x 1m, or 1m x 2m. It can be glued on fireproof (or directly purchase fireproof and soundproof cotton) according to the needs of customers, or cut and punched into the desired shape. If the user needs to use sound-absorbing sponge in the room, try to inform the designer of the decoration company about this requirement when decorating, or

At the time of procurement, the merchants are required to supply the laying performance.

Usually, it is not necessary to lay sound-absorbing sponges in the whole house. It is enough to lay half of the wall and the whole wall. Usually, the retail price of sound-absorbing sponges is about 35 yuan/square meter. The sound-absorbing sponge is slightly more expensive.

1. In the process of noise treatment of KTV walls, we need to use sound insulation boards, sound insulation cotton, and sound insulation felts, usually re-decorating sound insulation materials on the outside of the original wall.

The specific steps are to first build a layer of light steel keel structure, fill the structure with sound insulation cotton, and place sound insulation boards at both ends of the structure. AoBenz sound insulation boards are divided into several types, which can be bumped and convex according to the needs of KTV's sound insulation effect, and the installations are different. If you want to have a very good sound insulation effect, try to put sound insulation felt inside the board and between the structure, so that the sound insulation effect will be better.

2. In the sound insulation and vibration reduction of ktv floor, sound insulation felt and vibration damping pad are required.

The specific steps are to make the floor relatively flat, place a layer of vibration damping pad on the flat floor, and lay a layer of sound insulation felt on the vibration damping pad, so that the sound insulation effect will be better, and then irrigate cement or lime on it .

3. In the sound insulation treatment of ktv ceilings, it is necessary to use vibration damping hooks, sound insulation boards, sound insulation felts, and sound insulation cottons.

The specific steps are to build a light steel keel structure, install shock-absorbing hooks between the floor structures, fill the structure with sound insulation cotton, and stick a layer of sound insulation felt as much as possible.

The sound-absorbing sponge has a sound-absorbing effect, that is, it converts sound energy into heat energy. The sound insulation sponge does block the transmission of sound, but it is easy to cause sound energy reflection.
