* Two main objective tests, OAE (Oto-Acoustic Emission) and ABR (Auditory Brain Response), are used for evaluating hearing loss, with DP-OAE specifically targeting screening within the first 48 hours after birth.
* The research, conducted with 100 high-risk neonates, identified prematurity and low birth weight as the most common risk factors and emphasized the effectiveness of DP-OAE in early detection of hearing impairment.
