Sealing performance optimization: Ensure seamless fit between the window sash and frame, and use multi-channel sealing strips to prevent air-borne noise infiltration through gaps.
Glass matching design: Select glass with different thicknesses for the inner and outer layers to avoid resonance and improve sound insulation efficiency; the thickness of the glass and the width of the interlayer should be determined according to the target noise frequency band .
Frame structure reinforcement: Use reinforced profiles with high rigidity to reduce vibration transmission of the frame itself, and avoid rigid connection between the window frame and the building structure.
Ventilation noise control: If ventilation is required, equip with a silent ventilation system with sound-absorbing channels to ensure air circulation while maintaining noise reduction performance.
