ACOUSTIC PANEL
[Problem to be solved] A conventional sound absorption panel has problems in terms of flying of fiber, irritation (itching) to skin, and handling difficulty due to low self-standing performance. [Means to solution] In a sound absorption panel formed by stacking a plate perforated with a hole having a hole size smaller than a fiber length such as expanded metal, a honeycomb material, and felt-like fiber between the perforated plate and the honeycomb material, and joining the perforated plate, the felt-like fiber, and the honeycomb material to each other with an adhesive, the adhesive applied to the perforated plate is permeated into a surface of the felt-like fiber exposed from the hole to fix the fiber on the surface, thereby preventing flying of the fiber and irritation to skin. Further, the felt-like fiber is compressed strongly at positions facing the tips of a wall forming a cell of the honeycomb material, and a composite structure including the adhesive resin and the felt-like fiber is formed around the wall to increase strength, thereby ensuring the self-standing performance of the sound absorption panel.
