The hearing test is preferably performed within 2 weeks after birth, usually around day 5 of the postpartum period. Ideally, the test is done while the baby is asleep. A small earpiece is placed in the baby’s ear that emits a high-pitched sound. The test measures the echo that bounces back from the eardrum.
The results are given immediately. If there is too much background noise, the test may need to be repeated. The hearing test is usually arranged by the maternity nurse.
