Description

  The present invention relates to a sound insulation panel that forms a field wall and a partition wall provided inside a building.

  The boundary walls and partition walls in the panel method may be formed by sound insulation panels. This sound insulation panel is known to have a gypsum board, which is a sound insulation material, attached to a frame assembled with a core material, and a sound absorbing material such as glass wool is filled in the frame body to which this gypsum board is attached. (See Patent Document 1).

By the way, the sound insulation performance varies depending on the frequency range, and the sound absorbing material such as glass wool can efficiently absorb the sound wave in the high frequency range, but has little effect on the sound wave in the low frequency range. In order to insulate the sound in this low frequency range, it is necessary to increase the surface density of the wall panel according to the law of mass, so multiple gypsum boards of the sound insulation panel are stuck together or thicker than usual. I was stuck.
