Abstract (en)
Ventilated soundproof glass including at least two sheets of glass (1 and 4) and one sheet of plastic film (2) in between. These two sheets of glass and the sheet of plastic film have holes arranged in them. The sides of the two sheets of glass (1 and 4) adjacent to the sheet of plastic film (2) have grooves (12 and 42), by which the air can pass through the ventilated soundproof glass while the noise is substantially reduced when it is propagating through the long paths of the grooves (12 and 42) within the ventilated soundproof glass.
