Abstract:
(EN) Methods and apparatuses for addressing open space noise are disclosed. In one example, a method for masking open space noise includes receiving a microphone output signal from a microphone, the microphone one of a plurality of microphones in an open space. The method includes detecting a presence of a noise source from the microphone output signal, and determining whether the noise source is capable of being masked with a noise masking sound. The method further includes increasing a volume of a noise masking sound output from a loudspeaker responsive to a determination that the noise source is capable of being masked, the loudspeaker located in a same geographic sub-unit of the open space as the microphone. The loudspeaker is one of a plurality of loudspeakers in the open space.
(FR) L'invention concerne des procédés et des appareils pour traiter le bruit d'espace ouvert. Selon un exemple, un procédé de masquage de bruit d'espace ouvert consiste à recevoir un signal de sortie de microphone provenant d'un microphone, le microphone étant un microphone parmi une pluralité de microphones dans un espace ouvert. Le procédé consiste à détecter une présence d'une source de bruit à partir du signal de sortie de microphone, et à déterminer si la source de bruit peut être masquée avec un son de masquage de bruit. Le procédé consiste en outre à augmenter un volume d'une sortie sonore de masquage de bruit provenant d'un haut-parleur en réponse à une détermination que la source de bruit peut être masquée, le haut-parleur étant situé dans une même sous-unité géographique de l'espace ouvert que le microphone. Le haut-parleur est un haut-parleur parmi une pluralité de haut-parleurs dans l'espace ouvert.
