    Abstract: A method of manufacturing an Active Noise Reduction (ANR) device, comprising: providing at a stage during manufacture a pre-completion ANR device (1) in a non-final configuration, the pre-completion ANR device (1) comprising: a plurality of inputs (2); a plurality of signal processing resources (5); an output (3) for driving an earphone driver; and a programmable switch arrangement (4) capable of assigning any of the plurality of inputs (2) to any of the plurality of signal processing resources (5); selecting from the plurality of signal processing resources (5) a subset of signal processing resources to contribute to the output (3), whereby the remaining signal processing resources of the plurality do not contribute to the output in any mode of operation of the ANR device (1); and in a configuration step during manufacture, programming the programmable switch arrangement (4) to assign each of at least a subset of the plurality of inputs (2) to a different one of the selected subset of signal processing resources (5).

    Abstract translation: 一种制造有源降噪(ANR)装置的方法,包括:在制造期间在非最终配置中的预完成ANR装置(1)的一个阶段提供预完成ANR装置(1),包括:多个 的投入(2); 多个信号处理资源(5); 用于驱动耳机驱动器的输出(3); 以及能够将所述多个输入(2)中的任一个分配给所述多个信号处理资源(5)中的任何一个的可编程开关装置(4)。 从所述多个信号处理资源(5)中选择信号处理资源的子集以贡献于所述输出(3),由此所述多个信号处理资源的剩余信号处理资源不会对所述ANR设备的任何操作模式中的输出有贡献 (1); 并且在制造期间的配置步骤中,编程可编程开关装置(4)以将多个输入(2)的至少一个子集中的每一个分配给所选择的信号处理资源子集(5)中的不同的一个。
