            This test checks if the speech quality is not degraded by NC when
            the input is clean. During the test, the speech file will be played
            by Chameleon, while DUT records via the internal mic with NC enabled
            and disabled respectively. The score difference calculated by ViSQOL
            with the speech file as reference should not be less than the
            threshold specified in test_data.
