How to simulate room response in G.167 AEC? - dingkesun - Dec 7 10:05:00 2005



Hi, All
I¡¯m doing a project about G.167 compliant AEC. In the standard, it
says:
For teleconference systems, the reverberation time averaged over the
transmission bandwidth shall be typically 400 ms;

For hands-free telephones and videophones, the reverberation time
averaged over the transmission bandwidth shall be typically 500 ms;

For mobile radio telephones, a typical average ¡°reverberation time¡±
is 60 ms.
Are there any tools to simulate such long room response that are
similar to the real one?
Thanks

Kevin
