Megasorber
Acoustic Performance
Receive fast results to global standard: ISO 354:2003 ‘Acoustics – Measurement of sound absorption in a reverberation room’.
Quick setup, ability to test entire 3D-shaped objects, such as acoustic baffles, acoustic fins, even car seats and dashboard insulation.
Testing conveniently requires a small sample of about 1sqm, for any acoustic panels, perforated or slotted, timber slats and any 3D panel systems.
Megasorber Alpha Cabin is the only of its kind in the southern hemisphere.
This Swiss developed technology meets global standards.
Secure test results under calibrated sound field conditions of a full reverberation room without the burden of a full room test.
The innovative solution
Megasorber Alpha Cabin, a Compact Reverberation Room
Benefits
- Compact reverberation room test method.
- Ability to test a variety of acoustic systems & shapes.
- Quick set-up
- Small sample size about 1m2 (1.2m x 1m for a flat panel)
Traditional Test Methods for Sound Absorption
There are two normalised traditional methods:
- Impedance tube (or tube of Kundt) and
- Reverberation room.
1. The Impedance Tube (or tube of Kundt)
An example of Impedance tubes
Soundwave: Normal incidence
The waves arrive at the surface perpendicularly (normal incidence).
Advantages: small sample size. Fast and easy to measure.
Disadvantage: Does not simulate real life conditions. Unlikely for the sound waves to only arrive at the surface perpendicularly.
2. Full Size Reverberation Room
An example of Reverberation Room
Soundwave: Random incidence
Reverberation room: the angles of incidence are evenly distributed (random incidence).
Advantage: simulates real-life scenarios.
Disadvantage of Full Size Reverberation Room: Requires a large room (200 m3) and large samples (~ 10 m2 to 12 m2). Time consuming to obtain real measurements.
