About Acoustic Walls

Hebel autoclaved aerated concrete (AAC) provides excellent acoustic performance making it ideal for industrial acoustic wall and noise barrier construction. The Hebel range of extra thick AAC panels are effective acoustic walls and fire walls for power stations, substations, tunnels, freeways, train lines and noisy factories. They reduce noise pollution and protect communities from unwanted noise.

The PowerShield Acoustic Absorption Wall System delivers a resonant frequency barrier under 150HZ, far lower than other traditional alternatives. In fact, performance has been achieved with an absorptive rating of 0.95 at 100Hz using Helmholtz resonance principles. It can eliminate resonant noise at a close distance from the source, which provides an opportunity to utilise adjacent land that would otherwise be considered unsuitable for development.

Systems

PowerShield acoustic absorption wall system - for substation enclosures

Hebel PowerShield panels are 150mm to 300mm thick. They are part of an acoustic wall system which may incorporate a second layer of 75mm AAC panels for a tunable sound resonator system. This system is effective for power stations, substations and tunnels. It isolates noisy machinery, plant equipment and traffic.

SoundBarrier acoustic walls for industry, major roads, rail corridors

Hebel SoundBarrier panels are 150mm to 250mm thick and are installed horizontally in a single layer. They are used to significantly reduce noise from industry, freeways and railways.
