| Title |
Speech and multimedia Transmission Quality (STQ); A sound field reproduction method for terminal testing including a background noise database Sound field reproduction method for terminal testing |
||||||
|
Scope and Field of Application |
A sound field reproduction technique is described allowing the physical reproduction of real, prerecorded sound fields in a laboratory type environment. In contrast to other methodologies the technique is targeted to reproduce the spectral, temporal and spatial characteristics of sound fields. The method is intended to be used for testing modern type of terminals including advanced signal processing techniques including multi-microphone and array technologies. A background noise database is supplied with the standard taking into account types of background noise included in EG 202 396-1. This revision is to include new noise recording(s) in the database described in clause 8. If applicable, additional requirements on the maximum distortion and playback level of the loudspeakers/sub-woofer used in the sound field reproduction will be defined based on the new recordings. |
