Acoustic Material Characterization
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.
- Architectural Acoustics: Evaluation of wall panels, ceiling tiles, partitions, and interior finishes for NRC, STC,
and absorption performance. - Industrial Noise Control: Validation of materials used in enclosures, silencers, duct liners, and heavy
machinery insulation. - Product Development & R&D: Acoustic testing of new materials and prototypes for manufacturers and
OEMs. - Building Material Certification: Compliance testing for acoustic doors, windows, and glazing systems as
per ASTM/ISO norms. - Transportation & Automotive: Testing of sound-absorbing and damping materials for vehicles, trains, and
aerospace components. - Appliances & Consumer Electronics: Noise control materials used in HVAC systems, white goods, and
electronic enclosures. - Studio & Broadcast Environments: Acoustic treatment material selection and performance benchmarking.
- Hospitals & Educational Institutions: Ensuring safe, low-reverberation materials for sensitive environments.
- Public Infrastructure Projects: Acoustic validation of materials used in metro stations, airports, malls, and
convention centers.
