When the sound-insulating laminated glass with the sound absorbing material on the inner wall is applied to the building wall, the air flow mixed with noise from the air inlet (4) enters the sound-insulating laminated glass (10) along the air guiding line (6) The sound-absorbing material attached to the inner wall of the sound-absorbing expansion chamber (1) can continuously absorb the noise sound waves through the continuous sound-absorbing expansion chamber (1), and reduce the sound wave in the sound-absorbing expansion chamber (1) The reflection, diffraction and oscillation inside improve the sound insulation performance of the sound-insulating laminated glass.
