Examples of canal hearing devices including a lateral section having a frequency shaping sound port system are disclosed. A lateral section includes an elongate sound channel for receiving an incoming sound and producing a frequency-shaped sound output. The hearing device includes a microphone, a speaker for transmitting sound to the eardrum, and a sound port to receive the frequency-shaped sound output from the elongate sound channel and provide a pathway for the frequency-shaped sound output to reach the microphone.

Disclosed herein are systems and methods enabling hearing aid fitting by a non-expert consumer at home. The method in one embodiment involves delivering a sequence of test audio signals corresponding to natural sound segments to a non-acoustic input of a programmable hearing device in-situ, while allowing the consumer to adjust fitting parameters based perceptual assessment of hearing device output. The sound segments define a fitting soundscape representing a practical range of sounds within the normal human auditory range, with each sound segment corresponding to one or more fitting parameters of the programmable hearing device. The consumer is instructed to listen to the output of the in-situ hearing device and adjust controls related to corresponding fitting parameters. In one embodiment, the fitting system comprises a personal computer and a handheld device providing calibrated test audio signals and a programming interface. The systems and methods disclosed herein allow home dispensing of hearing devices without requiring specialized instruments or clinical settings.

Examples of systems and methods for rapidly grading the hearing of a user in accordance with WHO guidelines are disclosed. One example includes a personal computer and a test device configured to produce calibrated acoustic output at suprathreshold levels presented at an audiometric frequency range from 500 to 4000 Hz. The consumer's minimal response levels are registered, and a hearing ability score is presented to indicate a hearing grade and hearing aid candidacy. The hearing ability score may be representative of a classification of the WHO grading of hearing impairment. Systems and methods disclosed herein, with considerations for room noise present in the consumer's environment, allow for rapid hearing profiling, using a standard personal computer and minimal low-cost hardware, thus particularly suited for self-testing outside clinical environments such as at home, office, or retail store settings.

Examples of subscription-based wireless hearing device systems and methods are described. An exemplary system includes a wireless hearing device and a personal computing device to enable or disable a wireless service of the wireless hearing device in accordance of a subscription. The subscription may be verified using subscription data or validation data received from a remote server.
摘要:
A seal assembly for canal hearing devices including a dynamic pressure vent formed and defined by diaphragmatic flaps configured to open in response to a pressure gradient across the diaphragm. The seal assembly comprises a compliant seal element configured to be positioned generally concentrically around the canal hearing device for providing comfortable contact with the ear canal and for acoustically sealing the residual volume of the ear canal. The seal assembly is preferably made of an elastomeric material. The dynamic pressure vent is substantially closed in the normal position to minimize feedback, while momentarily opening inside the ear canal during insertion or removal of the canal hearing device into or from the ear canal.
摘要:
A hand held tool for safely inserting a canal hearing device into the ear canal having a medial end configured to simultaneously cradle the lateral end of the canal hearing device and constrain a knob element laterally positioned on the canal hearing device. In a preferred embodiment, the insertion tool comprises a C-shaped cavity for self-centering engagement with a D-shaped lateral end of a CIC device, providing ease of use for hearing impaired individuals. In a preferred embodiment, the insertion tool is substantially formed of a single monolithic structure for improved durability and lower cost of fabrication.

Examples of a rechargeable canal hearing device and charging systems are described. An exemplary rechargeable hearing device includes a battery module and a main module adapted to be removably couple together to form a modular canal hearing device assembly configured to be inserted inconspicuously in the ear canal. The modular canal hearing device assembly may include electrical contacts or an inductive charging system to couple charging energy from a charging station. According to examples described, the charging station includes a receptacle cavity shaped to partially accommodate the modular canal hearing device assembly including its handle. The receptacle cavity includes features operable to manipulate the handle as an actuator for automatically disengaging the battery module from the main module upon insertion of the lateral end into the receptacle cavity.

In one embodiment, a system includes a programmable hearing device configured to deliver a sequence of outputs in-situ, each output corresponding to a sound segment, wherein the outputs are delivered according to fitting parameters programmed into the programmable hearing device, and a computing device communicatively coupled online to a remote server. The computing device may be configured to receive a consumer input indicative of a subjective assessment of the consumer of each of the sound segments, wherein the consumer input is configured to adjust one or more fitting parameters associated with the output corresponding to the sound segment being assessed, wherein the fitting application is configured to make adjustments to the fitting parameters in accordance with the consumer input.
摘要:
A hearing device test system for use by a non-expert user may include a hearing device comprising a sound processor and a speaker and a portable test unit including a test microphone acoustically coupled to an exterior of the portable test unit via an acoustic calibration cavity. The portable test unit may include a coupler at an opening to the acoustic calibration cavity configured to receive the hearing device at least partially therein and the test microphone may be configured to produce a calibration signal input responsive to acoustic calibration stimuli provided by the speaker of the hearing device. The hearing device test system may also include a processor associated therewith and configured to measure a level of the calibration signal input.
