| Title |
Speech and multimedia Transmission Quality (STQ); Speech quality performance in the presence of background noise; Part 1: Background noise simulation technique and background noise database background noise: simulation & DB |
||||||
|
Scope and Field of Application |
-Speech quality performance in the presence of background noise reduction algorithms -Sound field simulation when directional microphones are used -The application area is hands-free terminals, mobile terminals, networks and car audio systems. This revision provides an update to the test room requirements and recommendations, and aims to achieve backwards compatibility with previous revisions while keeping the language concise. This revision allows to keep the acoustic conditions optimal even in smaller rooms. It also provides a practical benefit of reducing the system calibration complexity. |
