Method for improving the noise protection efficiency of pair-glass using inertia weights and the inertia weight

摘要

Glass units (Pair Glass) which is mainly used in windows and doors of the building there is a structure in which a constant air layer between the glass of the two-ply, this glass units has heat insulating properties compared to the normal one-layer glass window of only a kick, Noise the effect is almost the same as the single ply windows, or when badly rather than for a specific frequency sound. This phenomenon is a peculiar phenomenon of Resonant Tunneling in a double negative plate structure because it does not sound a certain frequency is almost blocked. Therefore, suppressing the resonance phenomenon of the transmission glass units can be significantly increased in the sound insulation performance.; The invention uses a method for preventing not cause Resonant Tunneling phenomenon between the two windows by attaching the inertia weight internal vibration damping material on one side of the glass units, and also to suppress the degree of increasing the sound insulation performance of the glass units and its which relates to the inertia weight.; And dance, and the cost of this inertia is very low, can be easily attached to the windshield at home, the sound insulation performance can be improved about 7 -8 dB.
