Patent ID: 10755689

Abstract:
An aircraft cabin system includes a plurality of modular displays disposed in an cabin and a server connected to each of the modular displays. Each of the plurality of modular displays includes a microphone that captures ambient noise in the cabin and a speaker that emits a noise reduction sound. The server instructs each of the plurality of modular displays to capture the ambient noise during a preselected flight phase. The server receives, from each of the plurality of modular displays, a digital ambient noise signal generated based on the ambient noise. The server generates for each of the plurality of modular displays a digital ambient noise reduction signal with an inverted phase of the digital ambient noise signal and a dynamic amplitude that is calculated to yield a highest level of ambient noise reduction. The server sends the digital ambient noise reduction signal to each of the plurality of modular displays. The speaker emits an ambient noise reduction sound with an inverted phase and a dynamic amplitude based on the digital ambient noise reduction signal.
