Introduction: Neonatal hearing screening (NHS) is essential for early detection of hearing loss, which may be congenital or acquired. Such loss could have educational, professional, and social consequences due to the great importance it plays in human communication and in the correct development of other fields, such as oral language. Government guidelines indicate that testing should be performed between 24 and 48 hours of life. However, in some cases, the NHS is not performed in this interval life time due to the time of discharge and/or clinical complications.
