Acoustic test cabin
Mecanum’s Acoustic Test Cabin (alpha cabin) is the perfect tool to measure diffuse-field sound absorption (NRC, SAA, Aw) and transmission loss (Rw, STC) of small size samples between 250 and 10 000 Hz.
Why Choose Mecanum’s Acoustic Test Cabin?
Follows ASTM C423, SAE J2883 and ISO 15186 standards
Choosing an acoustic test cabin compliant with ISO, SAE and ASTM standards ensures accuracy, reliability, and global acceptance. It offers precise measurements, compatibility with other equipment, regulatory compliance, and long-term value, making it a prudent choice for industries and research where absorption and transmission loss data are crucial.
Made for research, quality control and supplier validations
Originally developed for automotive OEMs and suppliers, Mecanum Acoustic Test Cabin (MATC) has evolved to become a versatile tool widely used in evaluating building insulation and soundproofing materials. Its operational range spans from 250 Hz to 10 kHz, effectively covering a broad spectrum of frequencies relevant to various industries.
MATC intuitive software enhances usability, making it an ideal choice for research and development purposes, quality control measures, supplier validations, and benchmarking exercises. Its capability to perform both absorption and transmission testing in a single setup ensures efficiency and cost-effectiveness for users across different sectors.
By integrating advanced technology with adherence to international standards, MATC stands out as a pivotal instrument for advancing acoustic material research and application in today’s demanding industrial landscape.

Measured properties
Absorption in diffuse fields
Diffuse field sound absorption (SAA, NRC, Aw) is based on ASTM C423 or SAE J2883 standards. Sabine’s method is used to determine the reverberation time of our MATC.
Transmission loss in diffuse fields
Diffuse field transmission loss (STC, Rw) is based on ISO 15186 standard. The intensity scan method is used to determine the sound power that goes through the panel.
