摘要： An ANR circuit, possibly of a personal ANR device, monitors a sound level of environmental sounds detected by a microphone external to an earpiece in which the ANR circuit is providing feedback-based ANR, and increases or decreases the degree of feedback-based ANR provided in response to the external microphone detecting a higher or lower sound level, respectively. Increasing and decreasing the degree of feedback-based ANR provided may be carried out by changing a variable loop gain of the ANR circuit and/or a range of frequencies of environmental sounds attenuated by the feedback-based ANR.

摘要： At initialization of an ANR circuit (i.e., at so-called boot time), attempts are made to alternately obtain ANR settings from an external storage device by operating the ANR circuit as a master of a bus and from an external processing device by operating the ANR circuit as a slave of the bus. Such alternating attempts may be repeated until the ANR settings are loaded.

摘要： An ANR circuit, possibly of a personal ANR device, incorporates an signal processing topology to support the provision of feedback-based ANR, feedforward-based ANR and pass-through audio in which the topology incorporates a branch in which feedback anti-noise sounds are generated from feedback reference sounds received from a feedback microphone, a branch in which feedforward anti-noise sounds are generated from feedforward reference sounds, and a branch in which modified pass-through audio sounds are generated from pass-through audio sounds received from an audio source, wherein these three branches are combined to combine the generated sounds of each branch into a single output by which an acoustic driver, possibly of the personal ANR device, is driven.

摘要： An ANR circuit, possibly of a personal ANR device, reduces the degree of feedforward-based ANR that it provides in response to receiving an indication of the operation of a manually-operable control. The reduction of degree of feedforward-based ANR may be effected by turning off or otherwise deactivating the provision of feedforward-based ANR, reducing a range of frequencies of environmental noise sounds attenuated by the feedforward-based ANR to provide less attenuation of sounds detected by a feedforward microphone that are in a range of frequencies deemed to be those of human speech, and/or creating a notch in the range of frequencies of environmental noise sounds attenuated by the feedforward-based ANR to provide less attenuation of sounds detected by the feedforward microphone that are in a range of frequencies deemed to be those of human speech.

摘要： In a personal ANR device having a pair of earpieces, each having a feedforward microphone and an ANR circuit associated therewith, each ANR circuit provides digital data representing environmental noise sounds detected by each ANR circuit's associated feedforward microphone. Such digital data may represent the environmental noise sounds as detected with little or not modification, or such digital data may be modified to some degree within each ANR circuit, perhaps to limit the range of frequencies that such digital data represents, before being provided to the other ANR circuit.
