Inclusion criteria

Inclusion criteria: 1.Adults with unilateral hearing loss: aged 18–60 years; normal hearing in the better ear, with a four-frequency pure-tone average (4f-PTA) <25 dB HL; affected ear (poorer ear) 4f-PTA between 40–70 dB HL, with stable hearing for =6 months; no diagnosed cognitive impairment, intellectual disability, or psychiatric disorders; all participants must complete a brief cognitive screening (e.g., MoCA) to exclude potential cognitive deficits; able to understand and comply with study assessments and training; voluntarily participate and provide written informed consent. 2.Adults with normal hearing: aged 18–60 years; four-frequency pure-tone average (4f-PTA at 500, 1000, 2000, and 4000 Hz) <25 dB HL in both ears; tympanometry showing type A tympanograms; able to cooperate with study assessments; voluntarily agree to participate and provide written informed consent.

Exclusion criteria

Exclusion criteria: 1.Active otologic disease; 2.Severe cognitive impairment, significant intellectual disability affecting self-care, or serious psychiatric disorders; 3.History of major structural brain lesions; 4.Cervical spine disorders preventing normal head rotation; 5.Any other conditions deemed by the investigators to render participation in the study inappropriate.
