Click on an image to enlarge  | The Melbourne City Link Project This project comprised 72,000 m2 of absorptive and reflective noise panels being completed over a 9 month period. The project involved the production of approximately 17,000 panels of standard panel dimensions of 3.6 * 1.2 metres. The absorptive panels were manufactued adopting 55 mm SoundTrap achieving a N.R.C. of 0.85 and totalled 17,000 m2 and the balance being reflective precast concrete panels.

Sound Transmission Class: 51 @ 55 mm thick
Density: 512 - 800 km/m^3
Compressive Strength: 2-5 MPa | | | | | | | Images
