    Abstract: 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.

    Abstract: Some demonstrative embodiments include devices, systems and methods of noise control. For example, a noise control system may be configured to process one or more first noise inputs from one or more first acoustic sensors, the one or more first noise inputs representing external noise sensed at one or more respective noise sensing locations on an outer surface of a sheltering structure; to process one or more second noise inputs from one or more second acoustic sensors, the one or more second noise inputs representing residual noise at one or more respective residual noise sensing locations on an inner surface of the sheltering structure; to determine a noise control pattern based at least on the one or more first noise inputs and the one or more second noise inputs; and to generate one or more control signals to control acoustic signals generated by one or more acoustic transducers based on the noise control pattern.

    Abstract: A driver/microphone assembly is suggested, in which the microphone (2) is arranged centred with the motor (8, 9) of the driver (1 ) between the membrane (4) and the motor (8, 9). In order to provide coupling between the microphone (2) and the space on the other side of the membrane (4) an opening (13) is provided in the membrane (4), which is located above the microphone (2). The inventive overall assembly requires a reduced space. The contacting wires (12) of the microphone (2) are led to the rear side of the assembly through a borehole (14) in the driver's motor (8, 9). The invention can advantageously be used in active noise cancelling headsets.

    Abstract: Active-noise-reduction (ANR) headsets protect the hearing of their users from loud persistent noises, such as airplane engines and construction equipment. These headsets generally include ear speakers and special circuitry to cancel or suppress certain types of loud persistent noises. One problem the present inventor recognized with active headsets, particularly those manufactured in mass quantities, concerns the performance variations that stem from inevitable variations in the fit of their earcups against heads of their users. For example, in putting on and taking off these headsets, some users experience low-pitched noises. Accordingly, the inventor devised, among other things, headsets that include front-cavity vents for equalizing the pressure between a front cavity portion of an earcup and an ambient environment.
