Acoustic Test Cabin

 

Mecanum’s Acoustic Test Cabin is the solution for a quick and accurate sound absorption and sound transmission loss tests on medium-sized samples.

The main double-hinged magnetic access door allows quick and safe access to the interior of the cabin while ensuring a high airtightness.

 
 

The test window on the access door is easily accessible and the change of samples is easy, which allows a large number of samples to be tested in a reduced period of time. 

The cabin is also mounted on wheels, in order to facilitate its movement. 

 

Four uncorrelated speakers are positioned in an optimal way to obtain the most homogeneous diffuse sound field.

 
 

four microphones antenna with a variable position is used to measure the sound field inside the cabin in an optimal way. In addition, four diffusers whose geometry and position are optimized are used to avoid interference in the measurement.

 
 

The acquisition system is connected to two Enviro Weather Stations, one inside and one outside of the cabin, to measure the atmospheric conditions at all times.

 

 

Sound absorption measurements are made according to a proprietary procedure closely related to ASTM C423 and ISO 354. Sound transmission loss is measured by evaluating the incident power from the quasi-diffuse field inside of the cabin and by measuring the transmitted power via a sound intensity scan on the surface of the tested sample. The method is similar to ISO 15186.

The interior dimensions of the cabin are 2,5m x 1,4m x 1,7m and those on the outside are 2,8m x 1,7m x 2,1m (these dimensions can be personalized optionally). The frequency validity range of the cabin is 315 Hz to 10 kHz and is checked by systematic comparison with classical tests using the reverberation and transmission loss facilities of the Acoustic Group of the Université de Sherbrooke (GAUS).
