摘要： An ANR circuit, possibly of a personal ANR device and possibly within an ADC of the ANR circuit, feedback reference data, feedforward reference data and/or pass-through audio data is provided to a secondary downsampling (and/or decimating) filter and/or is provided to a calculating block (e.g., RMS or absolute calculation block) to derive side-chain data to be output by the ANR circuit to a processing device coupled to the ANR circuit to employ the side-chain data in an analysis related to the provision of feedback-based ANR, feedforward-based ANR and/or pass-through audio by the ANR circuit. In an ANR circuit of a personal ANR device, a digital filter is structured to introduce one or more zeros to add gain to introduce positive phase in the provision of feedback-based ANR, wherein the gain follows a frequency-dependent "ski-slope" gain curve with little gain added at lower audible frequencies, with increasing gain that increases with frequency added at higher audible frequencies, and with the increasing gain flattening at frequencies above audible frequencies.

摘要： An electro-acoustic transducer or a device into which an electro-acoustic transducer is incorporated has at least two audio signal conductors through which the electro-acoustic transducer or device may be coupled to another device to convey analog audio signals representing sounds at a time when the other device places a relatively low DC bias voltage across the at least two audio signal conductors, and to be operated as a digital serial bus to exchange pieces of digitally-encoded data concerning the electro-acoustic transducer at a time when the other device places a relatively high DC bias voltage across the at least two audio signal conductors. A device into which an electro-acoustic transducer is incorporated has at least two audio signal conductors through which the device may be coupled to another device to convey analog audio signals representing sounds at a time when the other device places a relatively low DC bias voltage across the at least two audio signal conductors, and to be operated as either a digital serial bus to exchange pieces of digitally-encoded data concerning the electro-acoustic transducer or as a trigger to cause the electro-acoustic transducer to be bypassed to enable another electro-acoustic transducer to be tested at a time when the other device places a relatively high DC bias voltage across the at least two audio signal conductors. A device into which an electro-acoustic transducer is incorporated is able to be coupled to another device via one or both of a plurality of audio conductors implementing a digital serial bus and a wireless link by which digital data representing sounds either detected by or to be acoustically output by the electro-acoustic transducer may be exchanged to support at least an audio mode of the device. The device is also able to be operated in a test mode in which either analog signals or an altered form of digital data is able to be exchanged via the digital serial bus or the wireless link to enable testing of the electro-acoustic driver in situ as a component of the device and to enable data concerning characteristics of the electro-acoustic transducer derived from an in situ test to be stored for later use by the device to compensate for a characteristic of the electro-acoustic transducer during the audio mode.

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. 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.
