［産業上の利用分野］
本発明は、建材として用いる積層遮音パネルに関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a laminated sound insulating panel used as a building material.

する。これは、コインシデンス効果と呼ばれている。[Prior Art] In a homogeneous flat plate such as lauan plywood or plasterboard, the sound radiation efficiency of the plate increases and the sound insulation performance decreases in a frequency range where the propagation speed of bending waves in the plate is faster than the speed of sound. This is called the coincidence effect.

As shown in the figure, a laminated sound insulating panel is known in which a vibration damping material C having high viscous damping resistance, such as rubber, is sandwiched between boards A and B to integrate them.

ことを特徴としている。[Means for solving the problem] The present invention solves the above problem, and includes a damping material having higher viscous damping resistance than boards A and B between board A and board B. In the sandwiched laminated sound insulating panels, a groove is formed on the surface of at least one of the boards A and H that is in contact with the vibration damping material, and in the groove, a material with a higher viscosity than that of the boards A and B is formed. It is characterized by being filled with vibration damping material with high damping resistance.

コインシデンス限界周波数ｆｃが高音域に移動する。一
般に、遮音パネルの遮音量は、ボードのｆｃ付近で大幅
に低下し、ｆｃより高音域でも遮音低下現象は持続する

張り力を受けてボードの曲げ振動を抑え、ｆｃ付近及び
ｆｃ以上の周波数領域の遮音性能低下を改善する。[Function] In the above-mentioned sound insulation panel, because the board has grooves,
The coincidence limit frequency fc moves to a high frequency range. In general, the amount of insulation of a sound insulation panel decreases significantly near the fc of the board, and the phenomenon of reduced sound insulation continues even in a frequency range higher than fc. Therefore, moving the fc to a higher frequency range immediately leads to improved sound insulation.
Garu. In addition, the damping material in the groove compensates for the cross-sectional defect caused by the groove, and also suppresses the bending vibration of the board by receiving compression and tensile forces when the board bends, and has sound insulation performance in the frequency range near fc and above fc. Improve the decline.
