Each test case contains
- Target speech (male, 0 degrees) @ 0 dBr
- Spatially white noise @ -20 dBr
Additional noise sources are listed by test case. The level of each active noise source is 0 dBr.
Test case 1
- Babble from all 16 directions on horizontal plane
- Interferer speech (male, -67.5 degrees - i.e. left)
Test case 2
- Babble from all 16 directions on horizontal plane
- Interferer speech (male, -67.5 degrees - i.e. left)
- Interferer speech (female, 67.5 degrees - i.e. right)
Test case 3
- Babble from 7 directions on left side of horizontal plane (22.5 degrees <= azimuth <= 157.5 degrees)
Test case 4
- Babble from 7 directions on left side of horizontal plane (22.5 degrees <= azimuth <= 157.5 degrees)
- Interferer speech (male, -67.5 degrees - i.e. left)
Test case 5
- Babble from all 16 directions on horizontal plane
- Interferer speech (male, -67.5 degrees - i.e. left)
- Head rotated with respect to scene such that target is at -7.5 degrees
Test case 6
- Babble from all 16 directions on horizontal plane
- Interferer speech (male, -67.5 degrees - i.e. left)
- Head rotated with respect to scene such that target is at -15 degrees
