Noise Walls Project

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 x 1.2 metres.

The absorptive panels were manufactured 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.

The noise absorptive characteristics of these panels were as follows:

  • Noise Reduction Coefficient: 0.85 @ 55 mm thick
  • Sound Transmission Class: 51 @ 55 mm thick
  • Density: 512 - 800 km/m^3
  • Compressive Strength: 2-5 MPa
