Embodiment Construction

[0035] The actual measurement method of animal auditory tissue is to measure the auditory response of the auditory nerve layer and the auditory central layer of the brain for the solid tissue of the cochlea of ​​the animal. The experimental device is mainly carried out for the cochlear tissue of the animal. During the experiment, the head of the animal and the optical fiber were fixed, and there was no direct mechanical contact between the cochlear basilar membrane and the optical fiber port. The laser light emitted by the semiconductor laser is coupled into the optical fiber, and the wavelength, pulse width and energy of the laser can be adjusted by controlling the drive control circuit of the semiconductor laser. The system constitutes as image 3 shown.

[0036] The following experimental technical scheme was adopted:

[0037] The test platform includes sound processor, laser modulation driver, laser fiber array, animal tissue test box, array detector, data processing and...

Abstract

The invention discloses an animal auditory measurement system based on the optical fiber array laser sound effect. The animal auditory measurement system comprises a sound processor, a laser modulation driver, a laser optical fiber array, an animal auditory tissue test box, an array detector, a data processing module and a sound synthesis module, wherein the sound processor is connected with the laser modulation driver, the laser modulation driver is connected with the laser optical fiber array, signals output by the laser optical fiber array are transmitted to the animal auditory tissue test box, the response of the animal auditory tissue test box is output to the array detector, the array detector is connected with the data processing module, and the data processing module is connected with the sound synthesis module. The animal auditory measurement system has the beneficial effects that 1, the optical fiber array in dense layout is adopted; 2, the multichannel parallel synchronous optical pulse triggering without time distortion is adopted; and 3, the device practically measures the animal auditory sense, the measurement precision is higher, a measuring method is adjustable and controllable, and the data analysis is flexible and convenient.

Description

technical field [0001] The invention specifically relates to an animal auditory measurement system and method based on optical fiber array laser acoustic effects. Background technique [0002] The cochlea is an important sensory organ for the auditory system of animals (including advanced animals and humans) to receive sound information. Due to various reasons, this organ or the functional tissue associated with this organ loses its sensing function, and people suffer from severe sensorineural deafness, so that they cannot Normal listening and complete normal language communication functions. At present, for this type of deafness, electrode-type cochlear implants (that is, electronic bionic ears) implantation can be used to restore partial hearing. For example, a patent (CN200610027193.5) discloses a fully implantable cochlear implant and its preparation method. According to the mechanism and function of the cochlea, the device collects, transforms and encodes the external ...
