This paper discusses design and application of a new two-way acoustic transducer (Patent Applied For) for use in multiple sound reinforcement systems interconnected via regular telephone lines. This device provides hands-off voice intercommunication between large numbers of attendees in several remote conference rooms. The omnidirectional microphone and loudspeakers are included in a single assembly with pickup sensitivity and output radiation adequate for most conference rooms. High gain-before-feedback is accomplished by the chosen design and by acoustic phase cancellation.
