Conventional sound-absorbing panels were made by filling the space between the decorative panels with a sound-absorbing material or by simply stacking black perforated panels on top of each other. However, the sound absorption power is low in other frequency ranges, and the sound absorption power 1 for frequency fi

高めた吸音パネル（１）である。No. 1 and No. 711 show different embodiments of the present invention, in which the stiffness of the El1 body is increased, the amount of vibration is reduced, and the neck is made to act as a resonator by insulating air. This is a sound absorbing panel (1) that improves sound insulation through frictional resistance due to viscosity.

は極めて良好なのである。Since waves run vertically and horizontally in this sound absorbing panel (1), its bending rigidity is high. In addition, since it is a corrugated plate (4), the contact area between them is small, and the elasticity of the corrugated plate (4) in the direction of wave propagation is small, so the effect of the sound bridge is small. Since the corrugated plate material (4) is perforated with holes (5), the sound propagation path is carried out through the space between the crests of the waves and the holes (5), and the damping effect of this pseudo duct is large. Moreover, the holes (5) act as necks of the resonator, and the above-mentioned damping effect is further enhanced by the frictional resistance caused by air viscosity, and therefore, the sound absorption characteristics of this sound absorption panel are extremely good.
