Audioconferencing uses voice communication to link participants at two or more sites.
Traditionally, audioconferencing has been supported by standard telephone lines, but new
technologies are now starting to be used, such as Internet and ISDN. When more than one
person is at a location, speakerphones or special audioconference terminal equipment is
required. When more than two sites are involved, a telephone conference bridge (rented
from a telecommunications provider or provided by the institution) is needed; newer
systems may use Internet-based software. Successful audioconferencing requires good audio
quality, a reliable audio bridge, and comfortable listening conditions (high-performance
speaker phones or headsets, or both). It also requires careful planning of the sessions,
with a variety of activities and careful monitoring of turn-taking.
