Universal Neonatal Hearing Screening

Hearing is one of the five human senses and represents the ability to perceive sounds through the hearing system. The presence of normal auditory perception is one of the prerequisites for the emergence and development of speech in children. Conducting neonatal auditory screening is part of the early neonatal screening and incorporates examining infant’s hearing shortly after birth. A screening device is used that emits very low sounds with the help of simultaneous "otoacoustic emissions" from the inner ear of this acoustic stimulation. The latest researches show that in one or two in a thousand births the child has congenital deafness or impaired hearing. Aim: To acquaint midwifery students with the implementation of universal neonatal hearing screening using information from the Trakia Electronic University. Materials and Methods: The conducted survey allows us to study students' attitudes towards the audio screening. Study materials are accessible via the Internet in our e-university. The use of digital and multimedia materials is a way of enhancing the students' professional competence and the effectiveness of the learning process.
