Newborn screening checks for serious but rare and mostly treatable health conditions at birth. Most babies get their hearing checked as part of newborn screening before they leave the hospital after birth. The Centers for Disease Control and Prevention (also called CDC) and the American Academy of Pediatrics (also called AAP) recommend that all babies get screened for hearing loss before they’re 1 month old. How do you know if your baby has hearing loss?
In this condition, a problem with the inner ear or auditory nerve prevents the brain from understanding sound.
Auditory neuropathy spectrum disorder (also called ANSD). This when a baby has both conductive and sensorineural hearing loss. This kind of hearing loss is usually permanent. It may happen when certain cells in the inner ear are damaged. This happens when there’s a problem with the way the inner ear or auditory nerve works. This kind of hearing loss often is temporary and usually can be treated with medicine or surgery. Problems may include a blockage in the ear canal or fluid in the middle ear. This happens when there’s a problem in the outer or middle ear that slows or prevents sound waves from passing through. The auditory nerve sends sound information from the ear to the brain. The inner ear also has nerves that change sound vibrations into signals that travel to the brain through the auditory nerve (also called the hearing nerve). This is made up of the cochlea (a curled tube filled with fluid) and canals that help with balance. When the eardrum vibrates, it moves the ossicles. Sound coming into the ear moves through the ear canal to the eardrum, causing the eardrum to vibrate (move back and forth quickly). This is made up of the inside of the eardrum and three small bones called ossicles. The eardrum separates the outer and middle ear. This includes the part of the ear on the outside of the head, the ear canal and the outside of the eardrum. Problems in these parts of the auditory system may cause hearing loss: It makes sense of sound information as it travels from the ear to the brain. Your baby’s auditory system is the system in the body that helps her hear. If your baby shows signs of hearing loss at any time, call his health care provider to get your baby’s hearing checked. Seems to hear some sounds but not others. Turns his head if he sees you, but not if you only call out his name. Not saying single words like “mama” or “dada” by the time he’s 1 year old. Not turning toward a sound after he’s 6 months old. Signs of hearing loss in your baby can include: Hearing loss also can develop later in babies or during childhood or adulthood. When a baby is born with hearing loss, it’s called congenital hearing loss. Up to 3 in 1,000 babies (less than 1 percent) are born with some kind of hearing loss in the United States each year. Birth defects can cause problems in overall health, how the body develops, or how the body works. They may affect how the body looks, works or both. Birth defects are structural changes present at birth that can affect almost any part of the body. Profound: You can’t hear any speech sounds. Severe: You can’t hear any speech sounds when someone is talking at a normal level. Moderate: You can’t hear very many speech sounds when someone is talking at a normal level. 
Mild: You can hear some speech sounds, but soft sounds are hard to hear.Hearing loss can happen when any part of the ear isn’t working in the usual way.
