Hearing Loss (HL) Group: Participants must have a confirmed diagnosis of congenital sensorineural hearing loss (excluding conductive or mixed types). The fitting parameters for hearing assistive devices must meet clinical standards: hearing aids (HAs) must be verified using real-ear measurement, and cochlear implants (CIs) must be activated within one month post-operation and undergo regular programming. Additionally, written informed consent must be obtained from guardians, who must commit to compliance with follow-up procedures.
