There are a few ways to detect hearing loss very early in life. The oto-acoustic emission OAE test is the most common one and the first one used for newborn hearing screening programs. The echo that comes back is sent to a portable computer.
The computer can tell whether the baby heard the sound. The test, which takes 10 to 15 minutes, can often be done before your newborn baby leaves the hospital or at a designated hearing screening unit after leaving the hospital.
The Canadian Paediatric Society recommends that all newborns have their hearing tested. Many Canadian provinces and territories have universal newborn hearing screening programs—meaning all babies are tested at birth.
Families of babies who screen positive should follow up with a full hearing evaluation. Without newborn hearing screening and special tests, the signs of hearing loss can be very hard to find.

And what happens to hearing development during infancy and early childhood? Around 18 weeks of pregnancy, your little one hears their very first sounds. By 24 weeks, those little ears are rapidly developing. The limited sounds your baby hears around this point in your pregnancy are noises you may not even notice. They are the sounds of your body. These include your beating heart, air moving in and out of your lungs, your growling stomach, and even the sound of blood moving through the umbilical cord.
Around week 25 or 26, babies in the womb have been shown to respond to voices and noise. Recordings taken in the uterus reveal that noises from outside of the womb are muted by about half. Your baby is surrounded by amniotic fluid and wrapped in the layers of your body. That means all noises from outside your body will be muffled.
