Hello, this is Mr.I of Shizuka Co., Ltd..

Today’s article is about sound proof room construction for home theater.
※original article in Japanese (日本語の記事)

We performed a home theater soundproof construction of a private home. Construction that combines sound absorption and sound insulation becomes important as you arrange natural sound. In this construction, we  improved the feeling of sounds so good resonance of the deep bass occurs in the room.

Products such as ventilators, air conditioners, lighting etc. are generally soled with soundproofing specifications. However, since there is no change in making a hole in the wall, sound leakage will occur only by attaching it. Therefore, we will provide further soundproofing from here. There are air conditioners installed on the ceiling in a large room, but sound leaks on the ceiling behind. Even if you reinforce the wall and ceiling, you may be careful for the sound leakage in such case.

Soundproofing can be done in an existing room, but effects may not be easy depending on the condition of the building. For example, even if you want to dance or drum in a room on the second floor such as a multipurpose hall, we have to reinforce the floor and we will need more weight. As a result, it may be impossible to apply due to excessive loading, so you can only do halfway measures. Therefore, before inspecting soundproofing, it is absolutely necessary to investigate the detailed cross-section of the building, the type of music and musical instruments, the time zone in advance.
