Mecanum offers advanced impedance tube measurements for fast, precise analysis of acoustic material properties. Our services cover:
✓ Normal Sound Absorption Coefficient (NSAC)
✓ Normal Sound Transmission Loss (NSTL)
We provide high-resolution data across a wide frequency range (from 35 Hz to 10 000 Hz) to support material development, quality control, and product certification.
Why Accurate Impedance Tube Measurements Matter
Accurate characterization of acoustic materials starts with reliable impedance tube testing. These measurements form the basis for optimizing sound absorption, sound insulation, and acoustic performance across a wide range of industries.
Standards & Compliance
Our testing protocols strictly follow international standards for consistency and reliability:
NSAC Testing
✓ Standards: ISO 10534-2, ASTM E1050
✓ Deliver accurate sound absorption data
NSTL Testing
