Embodiment Construction

[0063] The detailed description given below in conjunction with the accompanying drawings serves as a description of non-limiting embodiments of the method and system according to the invention.

[0064] The following disclosure relates to a dual stimulation mode hearing aid system in which a first unit includes a cochlear implant adapted to generate electrical stimulation and a second unit includes an acoustic hearing aid for generating air-conducted acoustic stimulation. However, the invention is also applicable to a dual stimulation mode hearing aid system in which the first unit comprises a cochlear implant adapted to generate electrical stimulation and the second unit comprises a bone conduction hearing aid configured to provide bone conduction acoustic stimulation.

[0065] In one embodiment, the invention represents a situation where the first unit and the second unit are physically located close to the same ear. In another embodiment, the invention represents a situati...

Abstract

The application discloses a hearing aid system and a method of operating thereof. The system includes a speech processor communicatively coupled to a microphone. The speech processor is configured to process a microphone signal received at the speech processor for producing an electrical stimulation signal and an acoustic stimulation signal. The speech processor is also configured to generate a modified acoustic stimulation signal by modifying the acoustic stimulation signal at least for a part of a residual frequency range of a patient in dependence on effect of an implantable electrode array on mechanical properties of cochlea of the patient. The system also includes a first unit and a second unit. The first unit comprising a cochlear implant communicatively coupled to the speech processor, the cochlear implant comprising the implantable electrode array configured to be located within a cochlea of the patient and to provide the electrical stimulation based on the electrical stimulation signal to a cochlea within a non-residual frequency range of the patient. The second unit communicatively coupled to the speech processor and adapted to provide the modified acoustic stimulation based on the modified acoustic stimulation signal to the cochlea within the at least in the part of the residual frequency range.

Description

technical field [0001] The present invention relates to stimulating the ear of a user of a hearing aid system using different stimulation patterns. In particular, the invention relates to a hearing aid system comprising a first unit, such as a cochlear implant, and a second unit, such as an acoustic hearing aid or a bone conduction hearing aid. The first unit and the second unit are adapted to stimulate the same cochlea of ​​a hearing aid user. The invention also relates to a method of operating a hearing aid system. Background technique [0002] Innate hearing in humans involves the use of hair cells in the cochlea, which convert or transform acoustic signals into auditory nerve impulses. Hearing loss, which can have many different causes, is usually of two types: conduction and sensorineural. Conductive hearing loss occurs when the normal mechanical pathway for sound to reach the cochlea is blocked. These sound pathways can be obstructed, for example, by damage to the ...
