Artificial cochlea ad sound processing method thereof

Abstract

The invention relates to an artificial cochlea. The artificial cochlea comprises an external device and an implant, wherein the external device comprises a sound processing device and a power supply unit, the power supply unit is used for supplying power for the sound processing device, the sound processing device is used for processing acquired sound signals to form full frequency continuous sound signals which are sent to the implant, the continuous sound signals sent by the sound processing device are received by the implant, a spiral ganglion is further stimulated by utilizing electrical electrodes, and the continuous sound signals are transmitted to auditory nerves. The invention further relates to a sound processing method of the artificial cochlea. According to the artificial cochlea, after multi-channel sub-band processing on the sound signals, the sound signals are synthesized to form complete sine wave signals, the sine wave signals comprise all the sound information including tones, and patients are made to have real hearing feeling.

Description

technical field [0001] The invention relates to an artificial organ implantation device, in particular to an artificial cochlear and a sound processing method thereof. Background technique [0002] Cochlear implants, also known as electronic cochlea and bionic ear, are a special acoustic-electric transducer device that converts sound signals into electrical signals. By implanting electrodes into the remaining auditory nerves of the human ear, the externally received sound signals are converted into The electrical signal stimulates the remaining auditory nerve, thereby partially restoring the patient's hearing. This is currently the only medical method that can restore hearing to patients with severe or extremely severe deafness. [0003] The basic structure of a cochlear implant includes an extracorporeal part and an implant part. The extracorporeal part includes a microphone, a speech processor, a transmitting coil and connecting wires, and the implant part includes a rece...

AI Technical Summary

Problems solved by technology

[0004] The signal transmitted to the cochlea by the current cochlear implant cannot fully simulate the sound of the outside world, so patients cannot really understand the sound of the outside world, nor can they appreciate the beauty of the sound

In addition, because the implanted part includes the stimulator, when the chip in it is aging and fails, it needs to be operated again to replace the implanted part, which will undoubtedly bring great pain to the patient.
