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.

Presented herein are techniques that make use of objective measurements obtained in response to acoustic stimulation signals. More specifically, at least one measure of outer hair cell function and at least one measure of auditory nerve function are obtained from a tonotopic region of an inner ear of a recipient of a hearing prosthesis. The at least one measure of auditory nerve function and the least one measure of outer hair cell function are then analyzed relative to one another.

A device for Doppler optical coherence tomography (Doppler OCT), preferably of the human middle ear, is proposed. The device has an endoscope unit for at least partial insertion into the auditory canal. A sound source, a sound receiver, and OCT optics are integrated in the endoscope unit.

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.

A device is used to monitor, in real-time, one or more environment conditions of an environment in which a user is located. Based on the monitoring, an alert condition relating to the environment is detected. Based on detecting the alert condition, on-demand testing of a sensory component of the user is initiated. The on-demand testing tests for a selected condition relating to the health of the user.

Various embodiments are described herein to reduce sound sensitivities, improve state regulation, and/or reduce auditory processing and social engagement deficits in individuals with such deficiencies by recruiting the anti-masking functions of the middle ear muscles in order to optimize the transfer function of the middle ear for the processing of human speech. In certain embodiments, an individual may be subjected to a training protocol comprising one or more training sessions. During each training session, acoustic stimuli are provided to a subject for a period of time, with or without accompanying visual stimulation. A user response may be determined, for example, before beginning the protocol, during a session, after a session, and/or upon completion of the protocol. Such user response may be employed to adjust the acoustic stimulation, and the adjusted acoustic stimulation may be provided to the subject during a subsequent training session (or at a subsequent time within the same training session). The training protocol may end after a predetermined number of training sessions or upon achieving a desired user response. The training session may be characterized by a fixed protocol during which continuous stimulation is presented for a fixed period of time or by an interactive protocol during which the stimulation presentation is dependent on the reactions of the subject.

Generally, a method performed by one or more processing devices includes generating a graphical user interface that when rendered on a display of the one or more processing devices renders a visual representation of an environment and a visual representation of an object in the environment; retrieving an auditory stimulus with one or more auditory attributes indicative of a location of a virtual target in the environment; receiving information specifying movement of the object in the environment; determining, based on the movement of the object, a proximity of the object to the virtual target; adjusting, based on the proximity, one or more values of the one or more auditory attributes of the auditory stimulus; and causing the one or more processing devices to play the auditory stimulus using the adjusted one or more values.

Various embodiments include, for example, an audio device that operates by selecting one of a plurality of audio files in response to user interaction with a graphical user interface. The selected one of the plurality of audio files is decoded to generate audio output signals for playback of the selected one of the plurality of audio files via an audio output device. Animated auditory system display data is generated in response to the selected one of the plurality of audio files for display via a display device, wherein the animated auditory system display data animates action of at least one simulated cochlea in response to the selected one of the plurality of audio files. Other embodiments are disclosed.

A device and method for the continuous monitoring of otoacoustic emissions (OAE) levels on an individual worker uses as a pair of earpieces each featuring an external microphone, an internal microphone and a pair of miniature receivers. An adaptive filtering noise rejection processing of the measured distortion product OAE (DPOAE) is used to further improve the Signal-to-Noise ratio in frequencies where passive isolation remains insufficient. The adaptive filtering noise rejection technique relies on a Normalized Least-Mean-Square (NLMS) algorithm that uses the ipsilateral external microphone and the contralateral internal microphone to reject the noise from the measured DPOAE signals for each in-ear OAE probe. A DPOAE signal extraction algorithm provides for an increase in results reliability on a greater dynamic range in DPOAE magnitudes than known methods of DPOAE signal extraction. The device and method is suitable for the continuous monitoring of workers' hearing capabilities in industrial noises up to 75 dB(A).

A handheld radio device that incorporates within equipment typically carried by a first-responder but with added functionality which enables assessments of a subject's cognitive, auditory, visual, and speech function. In addition to providing two-way tactical radio functionality, the handheld radio device operates to generate haptic, audible, and visual stimuli, and then assess a subject utilizing the handheld radio device based on the subject's responses to the stimuli on the interfaces and sensors of the handheld radio device. Because this functionality is provided in equipment this is already typically carried by the first-responder, assessments that are more forward-deployed and closer to the point and time of injury, exposure, or period of interest can occur.
