Abstract: Aspects of the present disclosure provide methods and apparatuses for determining a nozzle of an audio device is, at least partially blocked. More specifically, based on a measured transfer function between the driver and a microphone and an expected transfer function between the driver and the microphone, a blockage is detected. In response to the detected blockage, the user is notified.

Abstract: A system comprising a computer program, at least one hearing device, and at least one stress evaluation device is disclosed. The computer program is executed in an external computing device. The at least one hearing device is worn by a user. The user wearing the at least one hearing device is in an environment defined by an acoustic scene. The at least one hearing device comprises one or more microphones, a processing unit, a speaker, and a wireless communication unit. The one or more microphones receive audio signals from audio sources in the environment and provide the audio signals to the processing unit which applies processing parameters to thereby process the audio signals. The speaker receives the processed audio signals and provides them to the user. The at least one stress evaluation device is also worn by the user and measures a stress parameter related to stress of the user, the stress parameter is related to the acoustic scene. The at least one stress evaluation device communicates with the external computing device and sends the measured stress parameter to the external computing device. The computer program determines an indication of stress of the user based on at least the stress parameter received from the stress evaluation device.

Abstract: This disclosure describes techniques for determining whether a user of a hearing instrument is located either indoors or outdoors. The hearing instrument has an ultraviolet (UV) sensor, a photoplethysmography (PPG) sensor and/or a spectrometer to determine whether the user is located indoors or outdoors. The hearing instrument uses energy converted by the UV sensor to charge a power source used by the hearing instrument. The UV sensor is used to determine whether an adhesive is properly cured and thus improve the manufacturing process for the hearing instrument. The UV sensor also works with other onboard sensors, such as the PPG sensor to determine if the user has hair or a head covering which is blocking the hearing instrument. If a user's hair or head covering is detected, the processing circuitry may adjust a pre-established heat balance equation, which determines a user's temperature.

Abstract: A sound processor comprises one or more electrical signal outputs configured to generate a plurality of electrical signals. The plurality of electrical signals are generated in specific tuned audio frequency bands in respective audio channels, in response to sound information received at the sound processor in the specific tuned audio frequency bands. The sound processor further comprises a transmitter coupled to the one or more electrical signal outputs for transmission of the plurality of electrical signals. The transmitter is configured to transmit the electrical signal in the respective audio channel over a separate respective transcutaneous communication link.

Abstract: A hearing device includes a receiver and a sound processor sending signals to the receiver. The receiver outputs audio signals from the signals sent by the sound processor. A base unit includes a main body having a cradle formed therein. A base unit microphone interfaces with the cradle and receives output audio signals from the receiver when the hearing device is received in the cradle. The base unit microphone and the receiver remain in open communication with a space exterior of the base unit when the hearing device has been received in the cradle. A processor associated with the system indicates a blockage of the receiver has occurred when a difference between the signal energy levels of test audio signals produced by the microphone, in response to the audio signals received from the receiver, and the signal energy levels of reference audio signals exceeds a threshold difference.

Abstract: Presented herein are techniques to enhance pitch coding in hearing devices, such as cochlear implants, by utilizing place of stimulation to more accurately and distinctly code frequency information pertaining to individual harmonics of a target harmonic signal, such as voiced vowel in speech or a harmonic tone in music. The techniques presented herein can be combined with a temporal pitch enhancement system to provide a combined system which operates over the voice and musical pitch range in which for example, pitch perception for low fundamental frequencies (F0s) is enhanced via the temporal pitch enhancement method and perception for higher F0s is enhanced via the spectral-place pitch coding method described in the present application. The techniques presented herein can also have application to enhancing coding of pitch and speech in acoustic hearing devices such as hearing aids.

Abstract: A hearing device configured to be worn by a user comprises one or more microphones, a processing unit, a speaker, a wireless communication unit, and stress evaluator. The user wearing the hearing device is in an environment defined by an acoustic scene. The microphones receive audio signals from audio sources in the environment and provide them to the processing unit which applies processing parameters to thereby process the audio signals. The speaker provides the processed audio signals to the user. The stress evaluator generates an indication of stress of the user, stress of the user being related to the acoustic scene. The processing unit then decides whether to perform an action on the basis of the received audio signals and the indication of stress of the user.
