Mecanum MATC Acoustic Test Cabin - Diffuse-Field Sound Absorption and Transmission Loss - ASTM C423, ASTM E2249, ISO 354, ISO 15186-1 and SAE J2883_201504 - Closed Cabin
Mecanum MATC Acoustic Test Cabin - Diffuse-Field Sound Absorption and Transmission Loss - ASTM C423, ASTM E2249, ISO 354, ISO 15186-1 and SAE J2883_201504 - Open Cabin

Mecanum’s Acoustic Test Cabin (aplha cabin) is the perfect tool to measure diffuse-field sound absorption and transmission loss of small size samples between 250 and 10 000Hz.

The double-seal magnetic access main door allows quick and safe access to the interior of the cabin while ensuring a high seal. The test window on the access door is easily accessible and sample changing is easy, allowing a large number of samples to be tested in a short period of time. The cabin is mounted on wheels to facilitate its movement.

Four uncorrelated loudspeakers are optimally positioned in order to obtain the most homogeneous quasi-diffuse field possible. A variable-position four-microphone antenna is used to optimally measure the acoustic field inside the cabin. Also, four diffusers whose geometry and position are optimized make it possible to avoid parasitic modes in the measurement.

The acquisition system is connected at all times to two weather stations, placed inside and outside the cabin, in order to measure atmospheric conditions at all times.
