板振動も抑制されず、遮音性能の低下が生じている。 In the case of the conventional panel, since the Young's modulus of the core material is considerably smaller than that of the front and back plates (1/10 5 or less), the influence of the core material on the bending vibration of the gypsum board is small, and the acoustic wave due to the coincidence is generated. Transmission occurs, and the sound insulation performance at high frequencies is reduced. Further, the plate vibration in the middle / low range is not suppressed, and the sound insulation performance is reduced.

性能が低下している。Further, since the loss coefficient of glass wool is small, low-range sound resonance transmission occurs in the conventional panel, and the sound insulation performance in the low-range sound is reduced.
