Experimentální: Hearing-aid intervention
Participants in the hearing-aid intervention group will receive standardized bilateral fitting of behind-the-ear (BTE) hearing aids, and their parents will be instructed to ensure consistent daily use for 12 months and be provided with essential knowledge regarding hearing aid maintenance and proper usage.
In addition, the same hearing-care education sessions will also be delivered to this group.
|
Bilateral BTE hearing aids will be uniformly provided by the project team and fitted and verified by experienced audiologists at participating sites, with settings adjusted to achieve optimal hearing status according to individual needs.
The devices will be selected from mainstream BTE hearing aid brands and models that are already commercially available in China and widely used in pediatric populations.
Standardized educational sessions covering children hearing and speech development, pediatric hearing care, routine monitoring and detection, and appropriate family support and parent-child interaction delivered by trained researchers during each follow-up visit.

Children overall development, as measured by General Developmental Quotient (GDQ) from the Griffiths Development Scales - Chinese Edition (GDS-C)
Časové okno: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
|
The GDS-C was adapted from the 2006 Griffiths Mental Development Scales - Extended Revised (GMDS-ER) and standardized with Chinese norms for children aged 0-8 years.
It evaluates six subdomains: (A) Locomotor, (B) Personal-Social, (C) Language, (D) Eye & Hand Coordination, (E) Performance, and (F) Practical Reasoning.
The General Developmental Quotient (GDQ) is derived as:(developmental age ÷ chronological age) × 100.
Higher scores indicate better overall developmental status.

Auditory Brainstem Response (ABR)
Časové okno: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
|
Electrical potentials recorded with scalp electrodes in response to electrical stimulation of the cochlear nerve.
The ABR threshold will be measured in decibels normal hearing level (dB nHL) for each ear.
Lower thresholds indicate better auditory function.

Behavioral audiometry thresholds (Pure-Tone Audiometry)
Časové okno: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
|
Behavioral audiometry measures the lowest pure tone level children can respond.
Its thresholds will be measured in decibels hearing level (dB HL) for each ear at standard frequencies.
The Pure Tone Average (PTA) will be calculated by the average of four frequencies (0.5, 1, 2, 4 kHz).
Lower thresholds indicate better hearing.

This scale includes the original MAIS version for children aged ≥3 years and the IT-MAIS (Infant-Toddler version) for children <3 years.
It is a parent-report structured interview designed to assess the child's spontaneous auditory responses in everyday environments, consisting of 10 items evaluating three domains: vocalization behavior, alerting to sounds, and deriving meaning from sound.
Each item is scored from 0 to 4, yielding a total score ranging from 0 to 40.

Distortion Product Otoacoustic Emissions (DPOAE) Amplitude and Signal-to-Noise Ratio
Časové okno: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
|
DPOAEs were recorded bilaterally at standard frequencies.
For each frequency, the DPOAE amplitude (in dB SPL) and signal-to-noise ratio (SNR, in dB) were obtained.
The amplitude represents the absolute sound pressure level of the distortion product response, while the SNR is the difference between the amplitude and the background noise floor at the same frequency.
Higher amplitude and SNR indicate stronger outer hair cell (OHC)-mediated cochlear amplification and better cochlear function.
A DPOAE response is conventionally considered present (PASS) when the SNR exceeds 6 dB.
|
From enrollment to 12 months, with assessments at 0, 6, and 12 months.
|
|
Acoustic Immittance
Časové okno: From enrollment to 12 months, with assessments at 0, 6, and 12 months.

Acoustic immittance is measured via tympanometry using a 226-Hz probe tone.
Three quantitative parameters are reported: tympanometric peak pressure (measured in daPa), peak compensated static admittance (measured in mmho), and equivalent ear canal volume (measured in mL).
Results are classified as pass or fail based on standardized criteria.
|
From enrollment to 12 months, with assessments at 0, 6, and 12 months.
