Abstract

The invention belongs to the technical field of a medical audiological detection system, and particularly relates to an otoacoustic emission simulation and test system. A fixing buckle of an acoustic input port is connected with an interface of an input end of a 2cm<3> coupling cavity to form a cavity, an earphone bracket is fixedly arranged in the cavity, an interface of an output end of the 2cm<3> coupling cavity is in sealed connection with one end of an interface bracket by an O-shaped ring, the other end of the interface bracket is connected with an acoustic receiving and output part of a simulation electrical cochlea, and the acoustic receiving and output part of the simulation electrical cochlea is connected with an electric control part of the simulation electrical cochlea to form the simulation electrical cochlea. The otoacoustic emission simulation and test system has the advantages that the basic functions of the human cochlea can be restored, and the actual otoacoustic emission effect can be simulated; the completeness and the effectiveness of the outputted otoacoustic emission signals can be ensured; and the size of a probe of the simulation electrical cochlea is the same as the size of a standard microphone for measuring, so on the premise of not damaging the characteristics of artificial ears, the direct replacement is realized according to requirements.

Description

technical field [0001] The invention belongs to the technical field of medical audiology testing systems, in particular to an otoacoustic emission simulation testing system. Background technique [0002] Otoacoustic emission is a very weak sound energy that is actively produced by the cochlea (it can also be induced by an instrument and induced by hearing). Otoacoustic emission detection is an objective hearing examination method starting from infants and young children. After giving a weak stimulation signal to the cochlea, the purpose of hearing examination is achieved by detecting this weak sound energy with probes and transceivers. [0003] In the current otoacoustic detection, because the acoustic signal of the otoacoustic is very weak, it is easy to be lost in the environmental noise, and the signal detected by the otoacoustic emission detector is also relatively small. When testing and calibrating otoacoustic emission detectors, it is difficult to simulate the otoaco...
