Introduction
The incidence of significant permanent hearing loss is approximately 1-3/1000 newborns. Neonatal hearing screening is carried out in the USA, UK and in Australia (2002 NSW Statewide Infant Screening Hearing Program, SWISH) There is a general guide giving a timetable for a number of simple responses that a neonate should make if hearing has developed normally (More? Neonatal Hearing Check List).
State Wide Infant Screening Hearing Program (SWISH) a newborn hearing testing program using an automated auditory response technology (AABR). Program was introduced in NSW Australia in 2002 across 17 area health service coordinators. It is thought that in NSW 86,000 births/year = 86-172 babies potentially born with significant permanent hearing loss.
Automated Auditory Brainstem Response (AABR) uses a stimulus which is delivered through earphones and detected by scalp electrodes. The test takes between 8 to 20 minutes and has a sensitivity 96-99%.
Neonatal Hearing Check List
The timing and types of responses listed below reflect only a rough guide for the general population. Abnormalities in neurological, visual or motor skill development can also affect responses.
- Birth to 3 months - Reacts to loud sounds, Quiets to familiar voices or sounds, Makes cooing noises, Responds to speech by looking at speaker’s face
- 3 to 6 months - Turns eyes or head toward sounds, Starts to make speech-like sounds, Laughs and makes noises to indicate pleasure and displeasure
- 6 to 9 months - Babbles, ‘dada’‘ma-ma’‘baba’, Shouts/vocalises to get attention, Will often respond to ‘no’ and own name, Responds to singing and music
- 9 to 12 months - Imitates speech sounds of others, Understands simple words, eg ‘ball’,‘dog’, ‘daddy’, Turns head to soft sounds, First words emerge
- 12 to 18 months _ Appears to understand some new words each week, Follows simple spoken instructions, eg ‘get the ball’, Points to people, body parts or toys when asked, Continually learns new words to say although may be unclear
- 18 to 24 months - Listens to simple stories or songs, Combines two or more words in short phrases eg ‘more juice’
