This invention discloses a hearing screening and tinnitus assessment method based on multi-frequency cross-analysis, specifically relating to the fields of hearing testing and neural information processing technology. It constructs an initial hearing vector in the individual frequency domain, generates a deviation feature vector based on a standard population database, extracts a set of abnormal frequency bands, and constructs a frequency domain focusing model. Multiple-intensity sound stimulation is applied to the abnormal frequency bands, and neural response parameter sequences are collected. Further cross-spectral analysis is performed to construct an individualized tinnitus resonance map, and the dominant frequency features and response intensity are extracted. Combined with subjective tinnitus scores, a tinnitus risk index is calculated, and a screening conclusion is output. This invention can achieve objective, quantitative, and spectral-level tinnitus identification, improving screening accuracy and clinical applicability.
