An audio circuit with an integral hearing test is disclosed. The circuit includes at least one variable gain amplifier (VGA) coupled to receive an audio signal and a plurality of filters. Each filter is coupled to the at least one VGA and configured to filter an output signal from the at least one VGA. A processor is coupled to the VGAs and configured to apply a selected frequency to the at least one VGA in a test mode and to control a gain of the at least one VGA in a normal mode.

A system and method are provided for automatic fitting of all audio signals according to the ear in which a user is using to receive audio signals from a host device. The host device incorporates an audio signal fitting device, which may comprise an inquirer configured to query the host device for an in-use audio producing transducer; an electronic mechanism configured to identify an ear which a user is using to receive audio signals from a host device, based on the in-use audio producing transducer; and a notifier configured to instruct the host device, based on the identified ear, to output a channel of audio signals to the in-use audio producing transducer. The ear in use may be deduced from inertial data. The instructions may specify a particular channel of audio signals, or enhancement thereof to adjust for characteristics of the identified ear, for example by applying frequency-specific gain adjustments to adjust for frequency response characteristics of the identified ear, and/or to adjust for a detected or typical signal pathway used to transmit a signal to the identified ear.

Embodiments include method, systems and computer program products for sound identification. Aspects include receiving, by a processor in a wearable electronic device, an indication of an audio signal. The audio signal is analyzed to determine an audio source and based at least in part on the audio source, non-auditory feedback is provided to a user of the wearable electronic device.

A binaural aid assistance system comprises first and second hearing assistance devices adapted for being located at or in left and right ears of a user. Each of the first and second hearing assistance devices comprises a) a first wireless interface comprising first antenna and transceiver circuitry adapted for establishing a first communication link to the respective other hearing assistance device based on near-field communication; b) a second wireless interface comprising second antenna and transceiver circuitry adapted for establishing a second communication link to an auxiliary device based on far-field communication. The binaural hearing aid system further comprises c) a user interface from which a user can select a suitable routing of an audio signal from the auxiliary device to each of the first and second hearing assistance devices.

Eyewear for enhanced hearing includes a first sound detector positioned on or adjacent a first lens of the eyewear, and a second sound detector positioned on or adjacent a second lens of the eyewear. A processing unit positioned on the eyewear is in communication with the first and second sound detectors. The processing unit utilizes software that includes instructions for determining a time differential between detection of a sound by the first sound detector and detection of the same sound by the second sound detector. Because the time differential is proportional to the angular displacement of the sound from directly in front of the eyewear or person wearing the eyewear, sound signals corresponding to detected sounds having an angular displacement less than a stored maximum angular displacement value can be preferentially enhanced and transmitted via a data transmission module to a hearing aid device.

This invention describes methods of Audio Signal Personalized Enhancement for optimal listening to music. A combination of hearing test, audio signal compensation, and signal processing algorithms are implemented jointly in an audio Device. An audio signal is processed and tuned within the entire range of audible frequencies to actively compensate for both the characteristics of the listening device, and the specific hearing characteristics of the listener, resulting in a much improved music listening experience. A randomized self-test algorithm is used to analyze user's hearing ability in each ear within a preselected dynamic volume range at multiple frequencies spanning the audible spectrum.

A method for modifying an audio scene and/or presenting additional information relevant to the audio scene includes capturing audio signals from the audio scene with a plurality of microphones; outputting an audio signal with a plurality of acoustical transducers; processing the captured audio signals, where the processing comprises one or more of filtering, equalization, echoes processing, and beamforming; separating and distinguishing audio signal sources using the processed audio signals; selecting at least one separated audio signal source; classifying the at least one selected separated audio signal source; retrieving additional information related to the classified audio signal source; and presenting the additional information in a perceptible form.

A system (202) for binaural signal processing. A first speaker (210) and a second speaker (220) are respectively mounted proximal to, and deliver respective first and second acoustic signals to, the left and right ears of a user. A first microphone (212) and a second microphone (222) are respectively mounted proximal to the left and right ears. A binaural processing device receives signals from the microphones and, based on the microphone signals, determines the first and second acoustic signals. The binaural processing device operates at a distance from both the left and right ears of the user. The speakers, microphones and the binaural processing device are connected by a signal network.

A binaural hearing device has first and second hearing aids and a control device. Each hearing aid has a communication unit, an audio receiver and an earphone. The communication units are configured for reciprocal data transmission by inductive coupling. The audio receivers receive and process stereophonic audio data. The control device switches one of the hearing aids to an inactive audio reception state and the other to an active audio reception state, swaps the audio reception states of the hearing aids within an operating period based on a signal strength of the audio signal of one hearing aid at a time, and drives the hearing aid with the active audio reception state to transmit audio data to the hearing aid with the inactive audio reception state via the communication units.

To enable a person to quickly and easily establish an audio profile for a TV, speaker, or other audio device, an audio profile is downloaded to the TV or speaker (and stored, if desired). The profile in the recipient device can be one of many that can be interchanged quickly on-the-fly. A voice assistant may enable the person to pick an audio profile from a list of audio profiles or user interface, either on the TV or the device the profile was created on. Using either method, voice assistant or UI, the profile can be downloaded from a mobile or PC device where the profile was created, or from the cloud where a previously created profile was uploaded and stored. A dual UI using voice and visual on-screen options makes the profiles accessible to most people.
