THE "BRAIN" MODEL OF INTELLIGIBILITY IN BUSINESS TELEPHONY
Polycom, Inc. Page 8 of 8
Conclusion
Recent advances in each of the major areas of the BRAIN model, combined with the fact
that each of these can support and compensate for the others, are making good audio
conference installations much easier to achieve, and with much better result. Regrettably
for Eric Blore and Fred Astaire, it will probably be awhile before such a facility is available
in Susquehanna jail, but dramatic improvements in business audio quality are today
available to the rest of us at reasonable cost.
