An exemplary system includes an electro-acoustic stimulation (“EAS”) sound processor, a cochlear implant communicatively coupled to the EAS sound processor, an electrode array communicatively coupled to the cochlear implant, and a receiver communicatively coupled to the EAS sound processor and configured to be in communication with an ear of a patient. The EAS sound processor 1) directs, while in a self-fitting mode, the receiver to apply acoustic stimulation to the patient, 2) records, using at least one electrode included in the electrode array, an evoked response that occurs in response to the acoustic stimulation, 3) compares the evoked response to a baseline evoked response recorded by the EAS sound processor prior to recording the evoked response, and 4) performs a predetermined action based on the comparison between the evoked response and the baseline evoked response. Corresponding systems and methods are also disclosed.

An information processing apparatus includes a processor. The processor is configured to output a caution, based on an operation history of a device, the device being worn by a user and emitting sound, and on a judging result regarding whether biological information concerning the user satisfies a condition for hearing loss.

A computer method for managing, processing and handling sensor signals from an in-ear monitor for immersive reality applications is provided. The method includes receiving, from a first electrode, a first electronic signal from a skin in a first ear canal of a user of an in-ear device, receiving, from a first microphone, a first acoustic signal from the first ear canal of the user of the in-ear monitor, and a second acoustic signal from a second ear canal of the user (binaural data capture), forming an acoustic waveform with the first acoustic signal, forming an electronic waveform with the first electronic signal, and identifying a health condition of the user based on the acoustic waveform and the electronic waveform. A device including a memory storing instructions and processors to execute the instructions to perform the above method are also provided.

An illustrative hearing system may be configured to receive, from a motion sensor included in a hearing device configured to be worn by a user, motion data representative of motion of the user while the user wears the hearing device and an output signal generated by a heart rate sensor in contact with the user. The hearing system may be further configured to determine, based the motion data, a heart rate probability distribution function and to determine, based on the output signal and the heart rate probability distribution function, a heart rate value for the user.

Presented herein are techniques for monitoring the insertion of an intra-cochlear stimulating assembly for the occurrence of one or more insertion stop conditions. The insertion stop conditions are detectable events indicating that movement of the stimulating assembly into a recipient's cochlea should be at least temporarily stopped. The insertion monitoring is based on objectively measured inner ear potentials, such as acoustically-evoked potentials.

A system for validation of a hearing aid performance, especially in small children is disclosed. The validation of the performance of hearing aids after having being fitted to a small child who is not able to subjectively provide responses to sounds presented to the child via the hearing aids, is instead done in an objective manner, by using a naturally occurring signal, which has been modulated in order to create an ASSR evoking speech stimulus which is not considered as noise by a hearing aid.

An exemplary evoked response measurement system includes a sound processor external to a patient and configured to direct a cochlear implant implanted within the patient to apply electrical stimulation to the patient. The measurement system also includes a headpiece configured to connect to the sound processor by way of a cable, affix to an external surface of a head of the patient, and facilitate wireless communication between the sound processor and the cochlear implant. The measurement system also includes a plurality of conductive contacts communicatively coupled to the sound processor and affixed to the external surface of the head of the patient to detect a signal representative of an evoked response generated by a brain of the patient in response to the electrical stimulation. At least one conductive contact is physically coupled to the headpiece and located between the headpiece and the external surface of the head of the patient.

An auditory ability test device based on optical coherence tomography of the present disclosure includes: a main console including a light source, a light classifier to classify light emitted from the light source into reference light and measurement light, a coherence signal collector to perform conversion into data from a signal by coherence of reference reflected light and measurement reflected light corresponding to reflection of the reference light and the measurement light respectively, and a calculator to calculate a 3-dimensional structure of a hearing organ and measure an auditory ability according to the data; a reference end to receive the reference light through an optical fiber connected to the light classifier and transmit the reference reflected light generated through a reflector to the main console; and a measurement end to receive the measurement light at one end through an optical fiber connected to the light classifier and generate a sound inside, the measurement end being inserted into the hearing organ through a speculum coupled to the other end to emit the sound and the measurement light and transmit the measurement reflected light reflected from the hearing organ to the main console.

A hearing test system comprises: a control device for controlling a hearing aid comprising a communication interface arranged to allow two-way communication and software for executing predefined sequences of sounds saved in a memory module of the device in response to an instruction from a control station equipped with remote control software; at least one hearing aid comprising a communication interface arranged to allow two-way communication with the control device, the device comprising a software layer for communication with the hearing aid and being arranged to provide a gateway between the control station and the hearing aid; and means for the sound insulation of the hearing aid.

The present invention concerns a method for the detection of distortion products of otoacoustic emissions (DPOAE), comprising the steps: (a) output of at least one first pair of primary tones each consisting of a first primary tone with frequency f.sub.1,1 and sound pressure level L.sub.1,1 and a second primary tone with frequency f.sub.2,1 and sound pressure level L.sub.2,1 with f.sub.2,1>f.sub.1,1, and (b) detecting evoked distortion products of otoacoustic emissions (DPOAE), characterized in that the first primary tone {f.sub.1,1, L.sub.1,1} is output with a time delay t.sub.lag after the second primary tone {f.sub.2,1, L.sub.2,1}.
