    Abstract: The present application discloses a hearing prosthesis configured to alert a user of the presence of sound while operating in a sound awareness mode of operation. When a user of the hearing aid removes the external sound processor and microphone, traditionally, a hearing prosthesis does not produce any audio stimulus. Here, the systems and methods will alert a user to sounds in his or her environment when the external sound processor and microphone are decoupled from the internal components of the hearing prosthesis. In some embodiments, the hearing prosthesis may have an acoustic receiver that is implanted in the recipient. The implanted acoustic detector may be used to detect an aspect of a sound above a threshold level. The threshold may be chosen so the detected sound is a loud sound such as a fire alarm.

  • Patent number: 11759634
    Abstract: In illustrative implementations of this invention, interferential stimulation is precisely directed to arbitrary regions in a brain. The target region is not limited to the area immediately beneath the electrodes, but may be any superficial, mid-depth or deep brain structure. Targeting is achieved by positioning the region of maximum envelope amplitude so that it is located at the targeted tissue. Leakage between current channels is greatly reduced by making at least one of the current channels anti-phasic: that is, the electrode pair of at least one of the current channels has a phase difference between the two electrodes that is substantially equal to 180 degrees. Pairs of stimulating electrodes are positioned side-by-side, rather than in a conventional crisscross pattern, and thus produce only one region of maximum envelope amplitude. Typically, current sources are used to drive the interferential currents.

  • Patent number: 11642525
    Abstract: An exemplary scalar translocation detection system detects a first evoked response occurring in response to acoustic stimulation applied to a cochlear implant patient. The system detects the first evoked response by way of an electrode configuration disposed on an electrode lead while the electrode configuration is positioned at a first location along an insertion path of the electrode lead into a cochlea of the patient. The system further detects, by way of the electrode configuration while it is positioned at a second location along the insertion path, a second evoked response occurring in response to additional acoustic stimulation applied to the patient. The system further determines an amplitude change and/or a phase change between the first and second evoked responses, and then determines whether a scalar translocation of the electrode lead from one scala of the cochlea to another has occurred based on the amplitude change and/or the phase change.

  • Patent number: 11641555
    Abstract: A processing device is interfaced with an auditory region of the brain of a subject that is responsible for auditory perception. The processing device receives signals associated with nerve impulses that are transmitted to the auditory region of the brain of the subject in response to sound collected by an ear of the subject. The processing device processes the received signals and generates at least one audio signal that is representative of the auditory perception, by the subject, of the sound collected by the ear. In certain embodiments, the processing device processes at least one audio signal that is representative of at least one sound to convert the at least one audio signal to a sequence of nerve impulses, and selectively provides the sequence of nerve impulses to the auditory region of the brain of the subject such that the subject audially perceives the at least one sound.

  • Patent number: 11633591
    Abstract: Cochlear implant systems can comprise an implantable subsystem comprising a cochlear electrode, a stimulator, a battery, and a first near field communication interface positioned subcutaneously proximate an ear canal. Cochlear implant systems can further comprise a removable earplug comprising a sensor, a second near field communication interface, and a signal processor. The removable earplug can be inserted into an ear canal to align the first and second near field communication interfaces. Once aligned, the battery can provide electrical power to the removable earplug via the near field communication interfaces. The signal processor can receive input signals from the sensor of the removable earplug and generate a stimulation signal representative of the auditory signals. The signal processor can communicate the stimulation signal to the stimulator via the near field communication interfaces.

  • Patent number: 11625994
    Abstract: Methods and systems are disclosed to facilitate creating the sensation of vibrotactile movement on the body of a user. Vibratory motors are used to generate a haptic language for music or other stimuli that is integrated into wearable technology. The disclosed system in certain embodiments enables the creation of a family of devices that allow people such as those with hearing impairments to experience sounds such as music or other input to the system. For example, a “sound vest” or other wearable array transforms musical input to haptic signals so that users can experience their favorite music in a unique way, and can also recognize auditory or other cues in the user's real or virtual reality environment and convey this information to the user using haptic signals.

  • Patent number: 11607309
    Abstract: Machine-learning techniques are used to train a classifier to predict auditory and language skills improvement in a patient who is a candidate for cochlear implantation (CI). One or more images of portions of the patient's brain are obtained, and quantitative data is extracted that represents the composition of one or more brain areas related to auditory and/or cognitive processing. For training of the classifier, data is obtained for previous CI patients whose improvement in language skills has been measured. Once trained, the classifier can be used to predict a likely degree of improvement in a prospective CI patient's auditory and language skills.
