Abstract: A bi-directional communication system is provided for mounting to a partition (e.g., a glass partition or a partition formed of a bullet-resistive material). The system is a self-contained system and is formed of several parts that mount together to form the assembled system. The system is not only a two-way, hands-free audio system that includes working audio components that deliver high-quality audio communication between people separated by the partition (i.e., a security or isolation barrier) but also the system provides high-quality video communication. The video communication is provided by a micro video camera that can be disposed on either or both sides of the partition.

Abstract: A bidirectional communication channel provides communication across a sound proof wall used, for example in a ticket booth. Normally communication from outside into the booth is muted by inhibiting the gain of a listen channel to a preselected percentage of its maximum gain level. After an attendant talks into an internal microphone, the muting is temporarily inhibited and normal communication is allowed between an attendant and a customer. After the conversation is completed, the system reverts back to a muted operational mode.
