Patent

CA 2528588

A system for providing audio information to persons in an approach path (12) includes an interaction point (14), and an approach path (12) leading to the interaction point. A parametric sound system (18) is provided, which includes a parametric speaker (20) disposed adjacent to the interaction point. The parametric sound system is configured for limited delivery of sound in a spatially limited audio zone (24) along the approach path (12), within a decibel level above ambient noise levels in the area of the interaction point (14), and sufficiently high to be heard primarily by a person progressing along the approach path (12). The interaction point can be a cashier station, and the system can also include a video display (16) configured to provide video information to persons in the approach path along with the audio information.

Cette invention concerne un système de diffusion d'informations audio à l'intention de personnes qui se trouvent sur une voie d'approche (12), comprenant un point d'interaction (14) sur lequel débouche la voie d'approche (12). Un système sonore paramétrique (18) avec haut-parleur paramétrique (20) est disposé tout contre le point d'interaction. Ce système sonore paramétrique est conçu pour fournir quelques informations sonores dans un espace d'audition limité (24) le long de la voie d'approche (12), à l'intérieur d'une plage de décibels supérieure au niveau de bruit ambiant dans la zone du point d'interaction (14) et suffisamment élevée pour être perçue principalement par une personne avançant sur la voie d'approche (12). Le point d'interaction peut être une caisse. Le système peut également comprendre un écran vidéo (16) conçu pour fournir aux personnes sur le trajet d'approche des informations vidéo parallèlement aux informations audio.
