the visualization of noise insulation function in double glass windows

Asahi Glass Co., Ltd.

The use of double glass windows for heat and sound insulation has been increasing. The function of airtight window sashes for sound insulation in todayÅfs urban housings has seen a notable improvement, but the problem of resonance could not be solved with double glass and was a long-time challenge for the industry.

The structure of “My-Mute” includes frame bars with small holes, placed between the glass panels to adjust the inner air pressure, preventing the resonance penetration phenomenon seen in double glass windows. It is a practical application of the principle of the Helmholtz Resonator.
