Embodiment Construction

[0045] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] In the prior art, the general signal processing unit’s prompt method for volume and mode is based on vision, and the user is reminded of the current use status of the device by means of indicator lights, such as the number of indicator lights and the rhythm of flashing, etc., see image 3 , including an indicator light 101, an increase key 102, a decrease key 103, a mode key 104 and a connection wire socket 105. The indicator light 101 is composed of 6 green LED lights, and the volume level is indicated by the number. If one indicator light is on, it indicates the volume 1, the volume is the smallest, and so on, 6 indicators are on, indicating that the volume is 6, and the volume is the highest. The position of the LED light is used to represent the mode number. For example, if the second LED light in the indicator light 101 is on, i...

Abstract

The invention discloses a cochlear implant signal processing unit and method based on auditory perception prompts. The method includes the following steps that the dynamic range of the auditory sense of a user generated through electrical stimulation of available electrodes is tested; the electrode channel threshold T and the comfort level C of the user are obtained, and a response curve of the user is obtained; a certain available electrode of the user is selected for sending a pulse train, and the volume level is set from low to high through the stimulation current; different levels of volume are adjusted by the user, the sounds heard by the user are different in loudness if the magnitudes of the stimulation current are different, and thus volume prompts based on stimulation loudness are achieved; encoding is performed according to the cochlear electrode position and frequency theory; it is set that stimulation is performed in different electrode positions in the mode of A-D, corresponding stimulation frequencies are different, and mode prompts based on stimulation frequencies are achieved. An intelligent prompting method capable of achieving subjective auditory perception according to different users is provided, the problems that a prompting method based on vision is not hidden and inconvenient are solved, and the user becomes more sensitive to volume and mode changes.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a cochlear implant signal processing unit and method based on auditory perception prompts. Background technique [0002] Hair cells in the human cochlea are sensory cells that receive sound. Severe hearing loss occurs when cochlear hair cell damage is severe. A cochlear implant is an electronic device that replaces damaged hair cells and regains sound signals through electrical stimulation of the auditory nerve. [0003] Cochlear implants are composed of two parts: extracorporeal machine parts and implant parts. The extracorporeal machine parts mainly include microphones (such as microphones, etc.), speech processors and transmitting coils. The implant parts mainly include receiving coils, stimulators and multi-channel electrode arrays. composition. When the system connection is normal, the microphone receives the acoustic signal, and the acoustic signal is analyzed, processed a...
