Title (EN) CHANGING THE ACOUSTIC PERFORMANCE OF A SOUND EMITTING DEVICE
(FR) CHANGEMENT DE LA PERFORMANCE ACOUSTIQUE D'UN DISPOSITIF D'ÉMISSION SONORE
Abstract:
(EN) A method for changing the acoustic performance of a sound emitting device is provided. The method comprises emitting (110) audible sound using at least one loudspeaker of the sound emitting device; capturing (120) the emitted audible sound using a microphone arrangement of the sound emitting device; and evaluating (130) the acoustic performance of the sound emitting device based on the captured audible sound and the emitted audible sound. The method further comprises changing (140) the shape of the sound emitting device based on the evaluated acoustic performance.
(FR) L'invention concerne un procédé pour changer la performance acoustique d'un dispositif d'émission sonore. Le procédé consiste à : émettre (110) un son audible au moyen d'au moins un haut-parleur du dispositif d'émission sonore ; capturer (120) le son audible émis au moyen d'un ensemble microphone du dispositif d'émission sonore ; et évaluer (130) la performance acoustique du dispositif d'émission sonore sur la base du son audible capturé et du son audible émis. Le procédé consiste en outre à modifier (140) la forme du dispositif d'émission sonore en se basant sur l'évaluation de la performance acoustique.
