Method and apparatus for multilingual simultaneous announcement system

An apparatus for open-field acoustic spatialized communication of announcements in an area in an enclosed structure to persons in different languages simultaneously, comprising:

• an enclosed structure;
• a plurality of non-parametric speakers spaced-apart and disposed in facing opposing relation on the interior ceiling and upper portion of the walls in an area in an enclosed structure;
• a storage device for storing signals representative of a plurality of announcements in a plurality of languages differing from each other;
• means for simultaneous communication of the signals representative of a selected one of the announcements for each one of the languages to at least one of the speakers;
• wherein the announcement, being communicated by the speakers with each speaker communicating one of the languages, is spatializedly discernable by persons in each of the communicated languages, means for modulating the announcement in at least one of the languages to further distinguish the announcement from the announcement in the other languages, wherein means for modulating comprises a low-pass filter for the announcement in the one of the languages.

A method of open-field acoustic spatialized communication of announcements in different languages simultaneously to persons in an enclosed structure, comprising:

• providing a plurality of non-parametric speakers spaced-apart and disposed in facing opposing relation on the interior ceiling and upper portion of the walls in an area in an enclosed structure;
• placing in a storage device signals representative of at least one announcement for each area in an enclosed structure in a plurality of languages differing from each other;
• communicating simultaneously the signals representative of the announcement in each one of the languages to at least one of the speakers in each area in an enclosed structure, the communicated announcement associated with the respective area in an enclosed structure;
• wherein the announcement, being communicated by the speakers with each speaker communicating one of the languages, is spatializedly discernable by persons in each of the communicated languages, the step of modulating the announcement in at least one of the languages to further distinguish the announcement from the announcement in the other of the languages, wherein the step of modulating comprises filtering the announcement in the one language with a low-pass filter.

A method of open-field acoustic spatialized communication of announcements in different languages simultaneously to persons in an area in an enclosed structure, comprising:

• at least two sets of audio communicators, each having at least two non-parametric speakers which are spaced-apart on the interior ceiling and upper portion of the walls in an area in an enclosed structure and each one of the two speakers connected for communication of an electrical signal with a respective one of the two speakers in the other set of audio communicators;
• means for storing signals representative of at least one announcement in at least two different languages each announcement associated with one of the areas in an enclosed structure;
• means for simultaneous communication of the signals representative of the announcement associated with one of the areas in an enclosed structure for each one of the at least two languages to a respective connected speakers in the two sets of audio communicators;
• wherein the announcement, being communicated by connected ones of the speakers in the two audio communicators in one of the at least two languages, is spatializedly discernable by persons in each of the communicated languages, means for modulating the announcement in at least one of the languages to further distinguish the announcement from the announcement in the other languages, wherein means for modulating comprises a low-pass filter for the announcement in the one of the languages.
