Title (EN) RECORDING HIGH OUTPUT POWER LEVELS OF SOUND AT LOW SOUND PRESSURE LEVELS
(FR) ENREGISTREMENT DE NIVEAUX SONORES DE PUISSANCE DE SORTIE ÉLEVÉS À DES NIVEAUX DE PRESSION SONORE BAS
Abstract:
(EN) Systems, methods, and apparatus are provided for recording high output power levels of sound at low sound pressure levels. For example, an apparatus includes an enclosure, a speaker disposed within the enclosure, and a microphone disposed within the enclosure. The speaker is configured to output a sound signal, wherein the sound signal is directed into the enclosure. The microphone is configured to capture the sound signal output from the speaker. A pressure level within the enclosure is reduced to a level that is at least 10% less than an ambient air pressure level outside the enclosure. The enclosure is sealed to maintain the reduced pressure level within the enclosure. The reduced pressure level within the enclosure attenuates a sound pressure level of the sound signal generated by the speaker within the enclosure, which in turn reduces a perceived loudness of sound that emanates from the enclosure.
(FR) L'invention concerne des systèmes, des procédés et un appareil d'enregistrement de niveaux sonores de puissance de sortie élevés à des niveaux de pression sonore bas. Un appareil comprend par exemple une enceinte, ainsi qu'un haut-parleur et un microphone situés dans l'enceinte. Le haut-parleur est conçu pour sortir un signal sonore. Ce dernier est dirigé dans l'enceinte. Le microphone est conçu pour capturer le signal sonore sorti du haut-parleur. Un niveau de pression dans l'enceinte est réduit à un niveau inférieur d'au moins 10 % à un niveau de pression d'air ambiant hors de l'enceinte. L'enceinte est fermée hermétiquement de façon à maintenir le niveau de pression réduit dans l'enceinte. Le niveau de pression réduit dans l'enceinte atténue un niveau de pression sonore du signal sonore généré par le haut-parleur dans l'enceinte, ce qui à son tour réduit un niveau sonore perçu du son qui provient de l'enceinte.
