How do you tell if a baby can really hear if he wears a hearing aid for the first time?

First of all, we must ensure that the hearing aids used by the child are properly adjusted to avoid under-magnification which will affect the child’s rehabilitation progress or over-magnification which will affect the child’s remaining hearing.

The real ear test is a method of measuring the actual sound pressure level at the tympanic membrane through a system.Through the real ear test, you can see how much the sound in the environment is amplified by the hearing aid and how much amplification is actually reached after the conduction of the child’s ear canal.

After the hearing aid is adjusted accurately, I want to know how loud the child can hear and whether it can be within the range of the long-term conversation sound spectrum?The child needs to pass the sound field to test the hearing threshold test before and after wearing the hearing aid, that is, the sound field test evaluation.
