Want to know how effective your material is at absorbing sound?
Acoustic Laboratory Thailand offers certified Acoustic testing, sound absorption measurement, and noise control material testing performed by experienced specialists.
All tests follow international ISO and ASTM standards , using a fully equipped reverberation room for construction materials, acoustic products, and noise barriers.
Main Sound Absorption Testing Methods
1. Impedance Tube – ISO 10534-2 / ASTM E1050
Ideal for small material samples such as:
- Acoustic foam
- Textile fabric
- Fiber-based materials
- R&D prototype materials
2. Reverberation Room – ISO 354 / ASTM C423
Suitable for larger acoustic products, including:
- Wall and ceiling acoustic panels
- Carpets and rugs
- Acoustic curtains
- Thermal and acoustic insulation
- Sound-absorbing noise-barrier elements
Test Results – Sound Absorption Coefficient (α)
The laboratory provides the Sound Absorption Coefficient (α) for each frequency band. These test results help:
- Architects and engineers design effective acoustic solutions
- Consultants select suitable acoustic materials for projects
- Manufacturers verify and improve sound-absorbing products
Sound Insulation Testing (ISO / ASTM)
In addition to sound absorption tests, we also perform sound insulation testing for:
- Walls and partitions
- Noise-barrier walls
- Building elements requiring acoustic performance verification
All sound insulation measurements are carried out in internationally standardized test facilities that comply with relevant ISO and ASTM requirements.
