Abstract: In general, in one aspect, a hearing aid has an ANR circuit and an ear tip that acoustically occludes the ear. Such a hearing aid provides greater gain to sounds than would be stable in the same hearing aid with a vented ear tip. The ear tip and the ANR circuit in combination attenuate sounds reaching the ear canal through the hearing aid to a first level. The hearing aid detects sounds arriving at a microphone, amplifies those sounds, and provides the amplified sounds to the ear canal at a second level and later in time than the same sounds arrive at the ear canal through the ear tip. The first level is at least 14 dB greater than the second level, such that the amplified sounds do not interact with the passive sounds to result in spectral combing.

Abstract: An earpiece includes a feed-forward microphone coupled to the environment outside the headphones, a feedback microphone coupled to an ear canal of a user when the earpiece is in use, a speaker coupled to the ear canal of the user when the earpiece is in use, a digital signal processor implementing feed-forward and feedback noise compensation filters between the respective microphones and the speaker, and a memory storing an ordered sequence of sets of filters for use by the digital signal processor. Each of the sets of filters includes a feed-forward filter that provides a different frequency-dependent amount of sound pass-through or cancellation, which in combination with residual ambient sound reaching the ear results in a total insertion gain at the ear of a user.

Abstract: A system for masking audio signals includes a microphone for generating an ambient audio signal representing ambient noise, a speaker for rendering masking audio, and a processor in communication with the microphone and the speaker. The processor performs spectral analysis on the ambient audio signal from the microphone to determine a spectral envelope of the ambient noise, adjusts a frequency response of an optimizing filter based on the spectral envelope, applies the optimizing filter to a baseline masking waveform, producing an output waveform with relative spectral distribution matching the ambient noise, and provides the output waveform to the speaker.

Abstract: A noise cancelling headset includes an earpiece, the earpiece including a feedback microphone, a feed-forward microphone, and an output driver. A first feedback filter receives an input from at least the first feedback microphone and produces a first filtered feedback signal. A first feed-forward filter receives an input from at least the first feed-forward microphone and produces a first filtered feed-forward signal. A first summer combines the first filtered feedback signal and the first filtered feed-forward signal and produces a first output signal. An output interface provides the first output signal as an output from the headset.

Abstract: In an active noise reducing headphone, a signal processor applies filters and control gains of both the feed-forward and feedback active noise cancellation signal paths. The signal processor is configured to apply first feed-forward filters to the feed-forward signal path and apply first feedback filters to the feedback signal path during a first operating mode providing effective cancellation of ambient sound, and to apply second feed-forward filters to the feed-forward signal path during a second operating mode providing active hear-through of ambient sounds with ambient naturalness.

Abstract: Stability is provided in an active noise reduction (ANR) headphone by measuring a sound field to generate an input signal, filtering and applying a variable gain to the input signal to produce a first filtered signal using a first filter and a variable gain amplifier in an ANR signal pathway, outputting the filtered signal, and simultaneously with outputting the first filtered signal, sampling a signal at a point in the ANR signal pathway and filtering the sampled signal using a second filter to produce a second filtered signal. The second filtered signal is compared to a threshold, and if the comparison finds that the second filtered signal is greater than the threshold signal, the gain of the variable gain amplifier is changed to attenuate the first filtered signal. The second filter applies different gains, different by at least 10 dB, in different frequency ranges between 10 Hz and 10 kHz.

Abstract: A system for providing binaural telepresence includes two communication devices, and two sets of active noise reducing headphones having an active noise-cancelling mode and an active hear-through mode, coupled to the respective communication devices and configured to provide left and right feed-forward microphone signals to the communication devices. The first communication device is configured to transmit the first left and right feed-forward microphone signals to the second communication device. The second communication device is configured to provide the first left and right feed-forward microphone signals to the second set of headphones. The second set of headphones are configured to activate their noise-cancelling mode while filtering the first left and right feed-forward microphone signals so that a user of the second set of headphones hears ambient noise from the environment of the first set of headphones, so that the user hears the ambient noise from the first set of headphones with ambient naturalness.
