A method for estimating an ear geometry of an ear of a user with a hearing device, the hearing device comprising an ear canal microphone, an external microphone, and a receiver, includes: obtaining an external input signal using the external microphone; providing an output signal by the receiver; obtaining an ear canal microphone input signal using the ear canal microphone; and estimating the ear geometry based on the external input signal and the ear canal microphone input signal.

A speaker of a hearing instrument generates a sound that includes a range of frequencies. Furthermore, a microphone of the hearing instrument measures an acoustic response to the sound. A processing system classifies, based on the acoustic response to the sound, a depth of insertion of an in-ear assembly of the hearing instrument into an ear canal of a user. Additionally, the processing system generates an indication based on the depth of insertion of the in-ear assembly of the hearing instrument into the ear canal of the user.

Embodiments herein relate to systems, devices and methods for fitting hearing assistance devices. In a first aspect, a method of fitting a hearing assistance device is included, the method including providing an audio sample to a hearing assistance device wearer, receiving input from the hearing assistance device wearer regarding a preferred sound volume or perceived loudness, receiving input from the hearing assistance device wearer with the external device regarding a bass/treble balance, and determining a maximum power output of the hearing assistance device that does not exceed a loudness discomfort level (LDL). Other embodiments are also included herein.

A device and method that supplements sensory input, thereby providing a supplemented sensory environment, to induce plasticity within the central nervous system that effectively overcomes sensory-neural processing deficits or strengthens specific sensory-neural abilities. In one implementation, ear-level hearing devices are used to deliver therapeutic sound with specific acoustic features that serve as archetypes of stimulus features for which sensory-neural processing is compromised by a sensory-neural deficit.

An exemplary fitting system 1) directs, during a fitting session, an EAS system to concurrently apply acoustic stimulation to a patient by way of a loudspeaker and electrical stimulation to the patient by way of an electrode located within a cochlea of the patient, 2) determines an interactive effect that the electrical stimulation has on the acoustic stimulation, 3) directs, if the determined interactive effect is suppressive, the EAS system to use, during a stimulation session, a first stimulation strategy that steers a current field produced by stimulation of the electrode away from intracochlear acoustic responders within the patient that are associated with the acoustic stimulation, and 4) directs, if the determined interactive effect is enhancing, the EAS system to use, during the stimulation session, a second stimulation strategy that steers the current field produced by the stimulation of the electrode towards the intracochlear acoustic responders.

An ear-worn electronic device comprises a housing configured to fit at least partially in an ear of a wearer, a power source situated in the housing, and a temperature sensor arrangement situated in or on the housing and coupled to the power source. The temperature sensor arrangement is configured to generate sensor signals in response to heat generated in the wearer's ear and a controller, situated in the housing and coupled to the power source and the temperature sensor arrangement, is configured to assess a fit of the device using the sensor signals.

A method and software program is used by patients in situ for fitting and refitting of a DSP-based hearing assistance device. Hearing is tested by selection of one of twenty four playbacks of speech, for each ear. Cognitive training/testing exercises test and train the user to relearn to distinguish between various sounds and particularly speech using the hearing assistance device. The preferred cognitive training/testing includes noise detection exercises, spatial hearing exercises, volume recognition exercises and speech differentiation exercises. The regimens for using the hearing aid depend upon the measured cognitive loss, with different sets of DSP parameters for self-directed, non-assessed cognitive training.

A method and software program is used by patients for fitting and refitting of a DSP-based hearing assistance device. An audiologist user interface and patient user interface include soundmaps and slidebars to control collections of hearing parameters within the DSP of the device. Based on cognitive testing and training of the patient, the range of adjustment allowed within at least the patient user interface is limited. The software therefore always maintains 100% safety for the patient and/or user to finetune the hearing aid parameters without worrying about selecting parameter values which would leading to slowing the cognitive learning of the patient.
