Re: speaker phones and listening in reverbation



 apart from the direct-to-reverb ratio with respect to amplitudes, there's
the question of signal path length. For a speakerphone, there is likely to
be more similarity between the time of arrival of the direct, and that of
the early reflections, and the reverberation, than for a close mic. I would
say the same thing for timbral quality /air absorption of Hf..?

I'm sorry, isn't there a really obvious reference (I just can't remember) to
do with suppression of echoes in a learned acoustic? (which I always assumed
was a binaural effect.)
As regards disambiguation of sources in complex auditory environments, with
reference to teleconferencing applications, British Telecom have been
experimenting with a variety of hybrid directional diffusion systems for
this application.
