The background insonation/notification System in a foyer

The power amplifiers, and ceiling and wall acoustic systems execute amplification and reproduction of sound signal. The evenly distribution conception of the sound pressure is used in the insonation due to the greater number of small power loud speakers. The location of loud speakers under the ceiling allows to insonify uniformly the apartment.

A sound signal from DVD/VHS-player, CD-player, tuner, computer, and etc. can be used as the sound sources. Verbal announcer/administrator announcements about the beginning of shows, information for work co-ordination of personnel in the extraordinary situations and other supplemental information can be used for notification.

It is also possible to broadcast different programs to the chosen areas. For example, soft background music and advertisements can sound in the hall, and information messages can sound in the official apartments. Thus, the casualty reports will sound with absolute priority above any other information.
