The Quality Assurance Lab tests the man/machine interface against international standards like ITU and ETSI. It is also used for further tests on voice quality once the modules and algorithms have been tuned and the mechanics and acoustic design are settled. Results of these tests allow us to benchmark our technology against others with quantifiable, reproducible data.   The QA Lab has four 150W JBL speakers and one JBL subwoofer controlled by a Head Acoustics ACQUA system.
