R-Cabin

R-Cabin is a small reverberation chamber which can be used to measure the sound absorption of materials for automotive industries.

Product Features:

 ● Appropriate for measurement of sound absorption characteristics of small and irregular samples, such as car seat, roof panel, carpet and etc.
 ● The size of the tested sample can be up to 3 square meters
 ● Frequency range: 400~10000Hz


Applications:
 ● Designing and optimization of the inner-car decoration acoustic system
 ● Testing of the sound absorption coefficients of the inner-car items
 ● Quality Control of the tested items
 ● R&D of new materials and new items


The system consists of:
 ● R-Cabin
 ● 4-Channel Data Acquisition and sound generator instrument MC3242 or MC3642
 ● 4 sets of microphones MPA 231
 ● 2 sets of OS002 sound source
 ● Audio Amplifier SWA-100

 ● VA-Lab software
 ● Standard samples for checking the measurement
