How accurate are hearing tests on newborns?

Can babies hearing improve?
Changes in hearing thresholds of NICU infants
One infant with normal hearing progressed to severe hearing loss. Five infants who had SNHL in the initial hearing tests showed a hearing threshold improvement of more than 20 dB (mean difference of threshold, 35 dB), and four of them recovered to normal hearing.
When does a baby’s hearing fully developed?

It plays sounds and measures an “echo” response that occurs in ears with normal hearing. If there is no echo, your baby might have hearing loss.

Can hearing damage be reversed?
Once damaged, your auditory nerve and cilia cannot be repaired. But, depending on the severity of the damage, sensorineural hearing loss has been successfully treated with hearing aids or cochlear implants. There is, however, the possibility that your hearing loss isn’t reversible.
