...We have run 72 test cases by covering the following test conditions: (1) two input SNRs: 6 dB and 12 dB, (2) two speech-levels at mouth reference point: 89 and 95 dBC, (3) two distance settings between device-under-test (DUT) and head-and-torso-simulator (HATS): 1 meter and 4 meters, (4) 9 types of noises: air condition noise, café noise, fan noise, living-room noise, office noise, pink noise, Pub noise, rain noise, and rock musical noise....
