PROBLEM TO BE SOLVED: To provide a sound absorbing panel capable of being easily installed and achieving sufficient sound absorbing effect.SOLUTION: A hollow box-shaped main body comprises a front plate constituting a front surface on which many open holes are formed and a back plate constituting a rear surface. A sound absorber is stored inside the main body. The front-back thickness at the upper part of the main body is made smaller than that at the lower part of the main body by forming an inclined part in which a distance between the front plate and the back plate decreases at upper side. A fixing member fixed on an installation surface is inserted into a mounting hole formed on an underside of the main body to make the main body installable on the installation surface, which enables the sound absorbing panel to be installed without installing a brace or other component that is formed on another body separated from the sound absorbing panel in advance.SELECTED DRAWING: Figure 1 |
