Abstract

This paper presents an assessment for the airborne sound insulation provided by double glazed panels. The glazed panels were glass, acrylic and polycarbonate with a thickness of 4 mm. The panels were tested for 10 mm, 20 mm and 30 mm air gap thicknesses. The experiments were conducted in a transmission loss facility consisting of semi anechoic and reverberation chambers complying with International Standards ISO 140-1 and ISO 140-3. The panels were subjected to airborne sound. Glass, acrylic and polycarbonate panel absorb noise most effectively above 500 Hz with the absorption peaks at 1000 Hz. The single number sound reduction index (RW) for glass, acrylic and polycarbonate as double layers with air gap were evaluated. The results showed that the glass has higher RW for all air gaps and the results were 40.5 dB, 37.7 dB and 37.4 dB, respectively. This could be attributed mainly to the material density which is higher for the glass.
