[Application of complete audiological evaluation battery in early hearing aid fitting for deaf children].
OBJECTIVE
To investigate the function of ABR and behavioral test battery in verifying the fitting of hearing aids on deaf children at early stage.


METHODS
Fifty-two children of age 1 to 9 were examined with the behavioral test battery or ABR. Based on the hearing thresholds thus obtained, DSL prescriptive formula was used to verify the fitting of hearing aids. Real ear measurement and sound field test were employed to assess the benefit of hearing aid. The children were subsequently followed up on a regular basis.


RESULTS
There was statistic difference between ABR and behavioral test battery (P < 0.05). Forty-one deaf children demonstrated significant benefit from hearing aid fitting while 4 showed no measurable benefit.


CONCLUSIONS
Both subjective and objective tests should be used for accurate hearing evaluation in deaf children. Hearing aid verification should be conducted accordingly. It is important to carry out early identification, intervention and rehabilitation.
