Embodiment 1

[0025] Such as figure 1 As shown, the embodiment of the present application provides a method for testing the speech perception ability of children with cochlear implants, wherein the method includes:

[0026] S100: Obtain a first-type masker and a second-type masker, wherein the first-type masker and the second-type masker are different;

[0027] Specifically, noise masking refers to the phenomenon that people's hearing threshold for a sound is increased due to the influence of noise, and the sound that causes this phenomenon is called masking noise, which is the masking sound defined here. The first type of masking sound and the second type of masking sound refer to masking noises that simulate different contexts in daily life, such as steady-state background noise, dynamic noise, language spectrum noise, and multi-person speaking noise; The first type of masker and the second type of masker cannot be the same type of noise.

[0028] S200: Obtain a first masking effect of ...

Embodiment 2

[0088] Based on the same inventive concept as that of a cochlear implant-using child's speech perception ability test method in the foregoing embodiment, as figure 2 As shown, the embodiment of the present application provides a speech perception ability test system for children with cochlear implants, wherein the system includes:

[0089] A first obtaining unit 11, the first obtaining unit 11 is configured to obtain a first type of masker and a second type of masker, wherein the first type of masker and the second type of masker are different;

[0090] A second obtaining unit 12, configured to obtain a first masking effect of the first type of masker sound;

[0091] A third obtaining unit 13, the third obtaining unit 13 is configured to obtain a second masking effect of the second type of masker sound;

[0092] A fourth obtaining unit 14, the fourth obtaining unit 14 is configured to input the first masking effect and the second masking effect into a masking separation mode...

Abstract

The invention provides a method and a system for testing the speech perception ability of a child using an artificial cochlea. The method comprises the steps that a first type of masking sound and a second type of masking sound are obtained; a first masking effect and a second masking effect of the first type of masking sound and the second type of masking sound are obtained; an energy masking effect and an information masking effect are obtained; the energy masking effect is input into an energy masking speech perception ability evaluation model, and a first energy masking speech perception ability evaluation result is obtained; the information masking effect is input into an information masking speech perception ability evaluation model, and a first information masking speech perception ability evaluation result is obtained; a first level of the first energy masking speech perception ability evaluation result is obtained; a second level of the first information masking speech perception ability evaluation result is obtained; a first weight ratio is obtained; and a speech perception ability evaluation result of a first child is obtained. The technical problem that in the prior art, a quantitative and qualitative evaluation means for the auditory masking effect of the child using the artificial cochlea under the multi-person competitive context is lacked is solved.

Description

technical field [0001] The invention relates to the technical field related to biological simulation, in particular to a method and system for testing the speech perception ability of children with cochlear implants. Background technique [0002] A cochlear implant is an electronic device that converts sound into electrical signals in a certain coded form by an external speech processor, and directly excites the auditory nerve through the electrode system implanted in the body to restore, improve and rebuild the auditory function of the deaf. Successful biomedical engineering setup. [0003] The use of cochlear implants in deaf children is a popular application object, and the noisy scenes in the daily environment require cochlear implants to have a good auditory masking effect in the context of multi-person conversations, that is, multi-person competition, so the evaluation of auditory masking effects It is of great significance to improve the auditory masking effect in th...
