Abstract: The amount of far-field noise transmitted by a primary communication device in an open-plan office environment is reduced by defining an acoustic perimeter of reference microphones around the primary device. Reference microphones generate a reference audio input including far-field noise in the proximity of the primary device. The primary device generates a main audio input including the voice of the primary speaker as well as background noise. Reference audio input is compared to main audio input to identify the background noise portion of the main audio signal. A noise reduction algorithm suppresses the identified background noise in the main audio signal. The one or more reference microphones defining the acoustic perimeter may be included in separate microphone devices placed in proximity to the main desktop phone, microphones within other nearby desktop telephone devices, or a combination of both types of devices.

Abstract translation: 在开放式办公环境中由主要通信设备发送的远场噪声的量通过在主设备周围定义参考麦克风的声学周长来减少。 参考麦克风在主设备附近产生包括远场噪声的参考音频输入。 主设备产生包括主扬声器的声音以及背景噪声的主音频输入。 将参考音频输入与主音频输入进行比较，以识别主音频信号的背景噪声部分。 噪声降低算法抑制主音频信号中识别的背景噪声。 限定声学周界的一个或多个参考麦克风可以包括在放置在主桌面电话附近的单独的麦克风设备中，在其他附近的桌面电话设备内的麦克风，或两种类型的设备的组合。
