Auditory Brainstem Response (ABR) testing is critically important for newborns as it plays a vital role in early detection of hearing impairments. Early identification of hearing loss through ABR testing allows for timely interventions, which are crucial for the development of speech, language, and cognitive skills. Without early diagnosis and treatment, children with hearing impairments may face significant developmental delays and social challenges. Therefore, ABR testing ensures that newborns with hearing issues receive the necessary support as soon as possible, improving their long-term developmental outcomes and quality of life.
