Problems solved by technology

[0004] Most of the existing technologies require the test environment to be equipped with a silent room, prolong the data collection time of the test process, and perform coherent averaging. This requires a high test environment, which cannot be satisfied in some grassroots screening hospitals.
In the process of detecting distorted otoacoustics, the detec

Embodiment Construction

[0031] The following describes the invention of the infant distortion otoacoustic detector and its detection method in detail with reference to the accompanying drawings.

[0032] Infant distortion ear sound detector of the present invention, see figure 1 , Including the probe housing 1, in the housing 1 are equipped with an electroacoustic ring energy device 2 (micro speakers) and an acousto-electric transducer 3 (micro microphone), the electroacoustic ring energy device 2 is used to play stimulation sounds F1 and F2 respectively , Acousto-electric transducer 3 is used to receive sound. The earphone silicone sleeve 5 placed in the ear is connected to the housing 1 through the transmitting and receiving sound pipeline 4, and the earphone silicone sleeve 5 can be designed in size according to the right ear of different months. A pure tone stimulation sound system is set in the housing 1. The pure tone stimulation sound system is the simulation software Matlab2015 to generate phase...

Abstract

The invention provides a baby distortion otoacoustic detection instrument. The baby distortion otoacoustic detection instrument is characterized in that electroacoustic transducers and an acoustoelectric transducer for receiving sound are arranged in a probe housing, an earphone silica gel sleeve placed in an ear is connected with the housing through a sound transmitting and receiving pipeline, and a pure sound stimulating sound system is arranged in the housing.A detection method comprises the steps that a probe transmits stimulation sound, the pure sound stimulating sound system broadcasts two paths of stimulation sound, imitating software is used for storing basic stimulation data which is generated in a header file of ear sound detection engineering, reflection sound is received, noiselevel is calculated, wave character value of a temporary domain interval in a tendency chart is calaculated, and the quality of collected signals is determined. The noise influence in the baby distortion otoacoustic detection process can be improved, the baby detection accuracy is improved, and besides, the detection duration is shortened.

Description

Technical field [0001] The invention relates to a medical hearing detection system, in particular to a baby distortion ear sound detector and a detection method thereof. Background technique [0002] Distorted otoacoustic emission (DPOAE) is an objective auditory function detection method, which relies on the integrity of the cochlea's overall function, and is an otoacoustic emission generated by the cochlear nonlinear distortion mechanism. Distorted otoacoustic emission is OAEs induced by simultaneously stimulating the cochlea with two initial pure tones F1 and F2 with a certain frequency ratio relationship. F1 and F2 can be continuous, or a pure tone signal with a long delay can be selected. Distorted otoacoustic emission stimuli are superimposed in the time domain and separated in the frequency domain. The relationship between F1 and F2 is F2 / F1=1.21, according to different frequency ranges, the ratio of F2 to F1 ranges from 1.18-1.27, and the effective otoacoustic signal fre...
