AI Technical Summary

Technical Problem

Existing technologies struggle to accurately assess the frequency characteristics, masking properties, and potential associations of tinnitus with multi-band hearing abnormalities, especially in children, the elderly, and patients with hidden tinnitus and normal hearing thresholds. Conventional single-frequency pure-tone testing methods are easily affected by subjective cooperation, resulting in low screening efficiency and poor diagnostic accuracy.

Method used

A hearing screening and tinnitus assessment method based on multi-frequency cross-analysis is adopted. By obtaining the initial auditory response values ​​under multiple frequency bands, constructing the initial hearing vector in the frequency domain, calculating the relative deviation coefficient, extracting abnormal frequency bands, performing multi-intensity incremental sound stimulation, recording neural response parameters, performing cross-spectral analysis, constructing an individualized tinnitus resonance feature map, and calculating the tinnitus risk index by combining subjective tinnitus level scores, the entire process of information collection and modeling is realized.

Benefits of technology

It significantly improves the accuracy and objectivity of tinnitus dominant frequency identification and assessment, and is suitable for screening occult tinnitus. The constructed tinnitus risk index TRI model comprehensively considers the degree of subjective perception and the intensity of physiological response, and is suitable for high-throughput primary screening and personalized diagnosis and treatment recommendations, with high sensitivity and adaptability.

Abstract

The invention discloses a hearing screening and tinnitus evaluation method based on multi-frequency cross-over analysis, and particularly relates to the technical field of hearing detection and neural information processing. An individual frequency domain initial hearing vector is constructed, a deviation feature vector is generated based on a standard crowd database, an abnormal frequency band set is extracted, and a frequency domain focusing model is constructed; performing multi-intensity sound stimulation on the abnormal frequency band, collecting a nerve response parameter sequence, further performing cross spectrum analysis, constructing an individualized tinnitus resonance spectrum, and extracting main frequency characteristics and response intensity; in combination with the subjective tinnitus score, calculating a tinnitus risk index and outputting a screening conclusion; according to the method, objective, quantitative and spectrum-level tinnitus recognition can be realized, and the screening precision and clinical applicability are improved.
