Estimating the term…
A unique, fully integrated, fully programmable, and highly flexible sound distribution system and methodology for providing masking sound, background music, and paging capabilities in up to eight zones of a building or space is provided. The methodology embodied in the system includes internal masking sounds that are uniquely pre-filtered to provide efficient and effective masking of distracting sounds within selectable zones of the space with a minimum masking sound dB sound level and with a pleasant sounding and non-annoying masking sound. The system also incorporates the capacity to be controlled from a remote or local telephone to adjust the volume level in any zone serviced by the system by issuing appropriate DTMF codes from the telephone's keypad. Unique bi-tone diagnostic functions are provided for assuring that the entire system is correctly wired and installed and for troubleshooting operational anomalies. ⅓ octave equalization is provided to compensate for known frequency response characteristics of the flat panel radiators of the system and to compensate for varying room acoustics to provide a low special variation of sound among the various zones of the space. The result is a high quality high fidelity sound that is consistent from zone to zone.
In a sound distribution system for distributing masking sound, background music, and paging to a plurality of zones within a space wherein the sound distribution system includes (i) a plurality of sound radiators located in the zones, (ii) a processor with a plurality of inputs, at least one of which being a telco input, and a plurality of outputs, and (iii) a plurality of power amplifiers having a plurality of inputs for receiving signals from corresponding outputs of the processor and a plurality outputs connected to and driving the sound radiators, a method of adjusting the sound level in one or more of the zones comprising the steps of:
A process for adjusting the sound characteristics of a sound distribution system that distributes sound throughout a space comprising the steps of establishing communication between the sound distribution system and a communications device capable of transmitting DTMF tones and communicating adjustment instructions to the sound distribution system by transmitting designated DTMF from the communications device to the sound distribution system.
A system for selectively distributing masking sound, music, and/or pages to a plurality of zones within a space, said system comprising:
