Ecotone Acoustic Limited offers precise acoustic characterization of materials to evaluate their real-world sound performance before integration into architectural or industrial applications. This service includes measurement of acoustic impedance, absorption coefficient, and transmission loss, following internationally recognized ASTM and ISO standards.
By analyzing how materials interact with airborne sound across a range of frequencies, we help manufacturers, designers, and consultants select or validate acoustic products with confidence. These tests are crucial for developing high-performance walls, ceilings, doors, panels, enclosures, and flooring systems.

characterization?\” open=\”no\”]
It is the process of scientifically measuring how a material absorbs, blocks, or reflects sound to determine its suitability for noise control and acoustic applications.
[/fusion_toggle][fusion_toggle title=\”Which acoustic properties are measured?\” open=\”no\”]
Key parameters include Sound Absorption Coefficient (α), Transmission Loss (TL), Noise Reduction Coefficient (NRC), and Acoustic Impedance, evaluated across multiple frequency bands.
[/fusion_toggle][fusion_toggle title=\”Which standards does PackSound follow?\” open=\”no\”]
All tests are conducted as per ASTM E1050, ISO 10534-2 (Absorption) and ASTM E90, ISO 717-1 (Transmission Loss) to ensure internationally accepted results.
[/fusion_toggle][fusion_toggle title=\”What materials can be tested?\” open=\”no\”]
We test foams, fabrics, composite panels, gypsum boards, metals, glass, mineral wool, wood, and other architectural or insulation materials.
[/fusion_toggle][fusion_toggle title=\”What deliverables will I receive?\” open=\”no\”]
You’ll receive a detailed test report with graphs, frequency-based performance data, and standard compliance notes, suitable for certification, R&D, or marketing documentation.
