Soundproofing panels sound high-end, right? Actually, they have a more professional name-damping soundproofing panels. This material is truly a balance of hard and soft, like an Oreo cookie, with two layers of boards sandwiching a layer of soundproofing material. There are two common types of soundproofing materials: damping soundproofing felt and damping adhesive. I've heard some manufacturers use asphalt, but in the high temperatures of summer, asphalt melts, making it counterproductive.
Outer Layer Materials
There are many choices for the outer layer materials, such as magnesium oxide board, gypsum board, fiberboard, and calcium silicate board. Among them, magnesium oxide board is the most commonly used because it's inexpensive and effective. There are many options for the thickness and weight of magnesium oxide board; the heavier the better. If you choose one with soundproofing felt sandwiched in the middle, the effect will be even better.
Residential or Commercial?
This type of soundproofing panel is generally used more in commercial projects, but it can also be used in residential projects. However, a professional installation team is required, especially for the ceiling. The effect is indeed quite good, achieving a sound insulation level of 30 to 45 decibels, but it's also quite heavy, typically weighing around 10 to 15 kilograms per square meter. Construction workers don't like this material because it costs extra!
Are there any alternatives?
Of course! A double layer of plasterboard sandwiching a 1.2mm thick sound insulation felt is a good choice. Ordinary carpenters can handle it, the effect is similar to sound insulation boards, and the installation is relatively convenient.
Summary
Therefore, those who want to soundproof can choose different sound insulation materials and combine them to achieve different sound insulation effects based on their needs. In short, soundproofing should be determined based on your specific circumstances.
