Embodiment Construction

[0035] The specific implementation disclosure of the present invention will be described in more detail below. figure 1 A frame diagram of the hearing assessment method based on speech intelligibility index proposed by the present invention. The specific implementation steps of the present invention include constructing the relationship between hearing threshold and speech recognition, constructing speech audiometry materials based on confusing disyllabic word pairs, parameter estimation, and selection of sound intensity conditions. The specific implementation process of each step is as follows:

[0036] 1. Establish the relationship between hearing threshold and speech recognition

[0037] This work uses the Speech Intelligibility Index (SII) to establish the relationship between hearing threshold and speech recognition performance. The frame diagram is as follows figure 2 shown.

[0038] The formula for calculating the speech intelligibility index is as follows:

Abstract

The invention discloses a hearing assessment method and equipment based on the speech intelligibility index. The steps include: 1) using the speech intelligibility index to establish the functional relationship between hearing threshold and speech recognition performance; Sound pair, consonant pair construct easily confusing two-syllable word pair corpus as the test corpus of speech audiometry, utilize the frequency band weight function BIF of this test corpus to measure the frequency band weight measurement method fast; Word pairs were used to perform speech audiometry on the subjects; then the sound intensity condition that maximized the likelihood value of the test results of confusing two-syllable word pairs was selected as the final hearing threshold of the subjects. The invention can also obtain relatively stable and reliable results in a non-professional environment, and has a high correlation with the results of pure tone audiometry, so it is a feasible solution to the hearing evaluation of mobile terminals.

Description

technical field [0001] The invention belongs to the technical field of hearing aids and relates to a hearing assessment method, in particular to a hearing assessment method and equipment based on a speech intelligibility index. Background technique [0002] Hearing loss is one of the important public health problems. According to the assessment data of the hearing disability status of its member states by the World Health Organization, there are more than 460 million people with hearing disabilities. million people suffer from hearing loss, accounting for 34% of the total population with disabilities. Hearing loss can impede communication, which affects relationships and the ability to work, leading to social isolation and reduced quality of life. Studies have shown that older adults with hearing loss are at higher risk of falls, dementia, depression and death compared to individuals without hearing loss. Children with hearing loss experience delays in language development...
