摘要： The present invention relates to a public address system comprising a first (1) and a second (1') amplifier module, each comprising an amplification means (2,2') and arranged for receiving a given signal to be applied to said amplification means and for outputting an amplified signal. The first and second amplifier module are interconnected via a first (LS1) and second (LS2) branch. At least the first or the second branch comprises at least one loudspeaker (11,11'). The first branch is arranged for feeding the amplified signal of the first amplifier module to the second amplifier module and the second branch is arranged for feeding the amplified signal of said second amplifier module to said first amplifier module. The first and second amplifier module further each comprise measuring means for performing comparisons on pairs of signals selected from the received given signal, the amplified signal output by the amplification means comprised in the amplifier module and the amplified signal of the other amplifier module and fed via the first or said second branch, and for yielding, based on those comparisons, an indication of the public address system's operational status.

摘要： A method and system for attenuating noise comprises identifying a location in an area at which sound emitted from one or more speakers has acoustic characteristics that are substantially similar in measure to corresponding acoustic characteristics of the emitted sound at a location approximated to be near an ear of an occupant of the area. A microphone, which may be a virtual microphone, is disposed at the identified location. The microphone detects sound at the identified location. In response to the sound detected by the microphone, the one or more speakers emit a noise-canceling audio signal adapted to attenuate one or more frequencies in the sound detected by the microphone.

摘要： The aim of the invention is to achieve a cleaner separation of a first audio signal in a first region of an area to be exposed to sound emitted by a plurality of loudspeakers. For this purpose, a calculating element calculates the version of the audio signals resulting from the spatially selective playback of the audio signals in this first region, calculates a masking threshold on the basis of the version of the audio signal that is to be separated from the one or more other audio signals in this region, and influences the output of the audio signals for the spatially selective playback to the outputs of the plurality of loudspeakers on the basis of a comparison of the masking threshold with the version of one or more other, i.e. interfering, audio signals.

摘要： Systems and methods of active noise cancellation are disclosed, that are for aircraft in-flight entertainment systems. An input is received from an input device that is processed to produce an output signal. The output signal is provided to at least one driver which is adapted to transmit the output signal to a user seated in a seat. The output signal is adapted so that, in use, the user hears a reduced ambient noise when seated in the seat.
