Abstract:
1. A method of supporting ANR analysis performed by a processing device coupled to an ANR circuit performing at least one of feedback-based and feedforward-based ANR in at least one earpiece of a personal ANR device, the method comprising: downsampling digital data representing reference sounds detected by at least one of a feedback microphone disposed within the at least one earpiece and a feedforward microphone disposed on a portion of the personal ANR device to derive a downsampled form of the digital data; operating an interface of the ANR circuit that couples the ANR circuit to a bus to which the processing device is also coupled to transmit the downsampled form of the digital data to the processing device as side-chain data; and operating the processing device to employ the side-chain data as an input to the ANR analysis.
