A silent room is what we often call a soundproof room. Its main purpose is to provide an acoustic environment for testing product noise. So in order to achieve the ideal silent effect, what materials are needed to meet the needs?

The ambient noise of a silent room is generally 70-80 decibels, and the lowest is 50-60 decibels. The sound in the silent room needs to reach 35 decibels, so at least 15 decibels of sound insulation is required, and the highest can reach 50-60 decibels, or even higher. So in order to meet the silent requirements, the materials used must have sufficient sound insulation effect. Let's explain it briefly.

First of all, we know that all objects that are making sounds are vibrating, and when the vibration stops, the sound stops. So if you want to soundproof, you must isolate the vibration, so vibration isolation materials are indispensable. The commonly used materials are damping materials and shock absorbers. The essence of a silent room is to prevent external noise from entering the room, so when we choose materials, we need both sound insulation and sound absorption. A single material cannot meet multiple needs at the same time, so a combination of multiple materials is required. Common materials include exterior panels, keel frames, sound-absorbing cotton, sound-proof cotton, fireproof cloth, microporous sound-absorbing panels, etc.

Because the silent room is used independently, it is necessary to meet the sound insulation effect while also being fireproof and moisture-proof and having a beautiful structure. Therefore, the external structure of the silent room needs to use exterior steel plates that have sound insulation effects, are fireproof and moisture-proof, and the surface is painted. In addition, there are some lighting facilities, ventilation facilities, monitoring equipment, etc.

The above are just some of the main materials, and some very detailed things will not be explained here. It should be noted that the materials used to make silent rooms must be safe and environmentally friendly. In addition to affecting the health of the user, better materials can also increase the service life of the silent room.
