建築物における窓ガラスに広く用いられている。(Prior Art) Conventionally, sound-insulating laminated glass has been known in which an adhesive interlayer film, typically a plasticized polyvinyl butyral film, is laminated and bonded between opposing glass plates. It is widely used for window glass of transportation vehicles such as automobiles and window glass of buildings.

デンス効果による遮音性能の低下が避けられないのが実
情である。Recently, for example, with the aim of further improving the residential environment, such sound-insulating laminated glass has come to be required to have even higher sound-insulating properties. There is a strong demand for improved sound insulation. This coincidence effect is caused by the stiffness and inertia of the glass when a sound wave is incident on the glass.
This is a phenomenon in which transverse waves are transmitted on the glass surface, and the incident sound resonates with the transverse waves, resulting in sound transmission. Conventional sound-insulating laminated glass as mentioned above has a
The reality is that in a frequency range centered around 0 Hz, a reduction in sound insulation performance due to such a coincidence effect is unavoidable.

問題となるのは、コインシデンス効果によって生じる透
過損失量の極小部（以下、この極小部の透過損失量をＴ
Ｌ値という。）である。Firstly, the sound insulation performance of sound insulation laminated glass is expressed as the amount of transmission loss with respect to frequency. Conventional laminated glass, as shown in Figure 1, has a high frequency range of 2000
In the vicinity of Hz, the sound insulation performance decreases due to the coincidence effect. According to JIS, the sound insulation class is 500Hz.
In the above, the amount of transmission loss is expressed as a constant value. Therefore, the problem with deterioration of sound insulation performance due to the coincidence effect is the minimum part of the transmission loss caused by the coincidence effect (hereinafter, the transmission loss of this minimum part is T
This is called the L value. ).

い。Therefore, conventional methods of increasing the TL value have been proposed, such as increasing the mass of the laminated glass, subdividing the glass area, increasing the side ratio of the glass, and improving the method of supporting the laminated glass plate. Since it is not very effective and causes disadvantages in other aspects, it cannot be called a practical improvement method.
