Movable mute room
The invention discloses a movable mute room. The movable mute room comprises a room body and two sound insulation plates, wherein the two sound insulation plates are respectively connected to the front and rear sides of the room body; a closed cavity is defined by the room body and the two sound insulation plates; an outer plate, a hollow plate, an inner plate and a sound absorption plate are arranged on the room body in sequence from outside to inside, the outer plate, the hollow plate and the inner plate are fixedly connected, and the sound absorption plate is attached to the inner plate; and the hollow plate is filled with sound-absorbing cotton. According to the movable mute room, the sound insulation performance can be effectively improved, a critical frequency point does not move to low frequency, the low-frequency sound reduction index is guaranteed, additionally, the sound absorption plate is further arranged on the inner plate, so that the sound reduction index is further increased, and the sound insulation effect is guaranteed.
本发明公开一种可移动式静音房，包括：房体，分别连接在所述房体前后两侧的两隔音板；所述房体与所述的两隔音板围成密闭空腔；所述房体从外到内依次设置有外层板、中空板、内层板、吸音板，所述外层板、中空板、内层板固定连接，所述吸音板贴附在所述内层板上；所述中空板内填充有吸音棉。本发明可有效提升隔声性能，保证临界频率点不向低频移动，保证低频隔声量，同时在内层板上还设置有一层吸音板，进一步提高隔声量，保证隔音效果。
