A newborn’s subtle reactions to sound, such as startling at a sudden noise or calming to a parent’s voice, are comforting, but they are not definitive proof of healthy hearing.
Newborn hearing screening provides an early check of a baby’s hearing and can indicate whether further evaluation is needed.
This is particularly relevant in the Philippines, where a 2023 study reports that permanent bilateral hearing loss occurs in about 0.13% of live births. The study also estimates that an untreated case costs around PHP 4.3 million in special care, special education, and lost income during adulthood.
What are the Most Common Causes of Hearing Loss in Newborns?
Several risk factors raise the likelihood of hearing loss in newborns, including:
Family History: Genetic factors can increase a newborn’s risk of hearing loss when there is a family history of hearing loss.
Maternal Infections: Infections such as cytomegalovirus (CMV) or rubella can pass from mother to baby during pregnancy and affect the baby’s auditory system.
Ototoxic Medications: Certain medications used during or after birth can damage the inner ear and cause hearing loss.
Birth Complications: Birth trauma or a lack of oxygen during delivery can affect a newborn’s hearing.
Premature Birth: Babies born prematurely may be at higher risk of hearing loss because their auditory system may not be fully developed.
High Bilirubin: Severe jaundice can cause kernicterus, a form of brain damage that can lead to hearing loss.
Postnatal Infections: Newborns can develop infections such as meningitis after birth, which may affect hearing.
What are the Signs of a Baby’s Hearing Problem?
Even if a baby passes their initial screening, hearing loss can sometimes develop later due to illness, trauma, or genetics. Monitoring key developmental milestones helps you identify and assess changes in your child’s hearing or communication promptly.
Infants (Birth to 6 Months):
Does not startle or blink in response to sudden loud sounds.
Does not seem to recognize or become soothed by a parent’s voice.
Does not turn toward or otherwise respond to sounds.
Toddlers and Young Children:
Demonstrates delayed, limited, or unclear speech for their age.
Rarely looks up or responds when spoken to.
Watches television or listens to other devices turned up louder than usual.
What is Newborn Hearing Screening?
Newborn hearing screening is a quick, non-invasive and painless test performed shortly after birth to check whether a baby’s hearing has developed as expected. While it differs from a full diagnostic evaluation, both procedures are painless, take only a few minutes per ear, and can often be completed while the baby sleeps.
A screening is a quick check used to identify newborns who may need further hearing assessment.
A diagnostic evaluation is a more detailed assessment used to confirm whether hearing loss is present.
Why is Newborn Hearing Screening Important?
Newborn hearing screening can identify hearing difficulties early for timely follow-up and support when needed.
Hearing Difficulties May Not Be Obvious: Newborn hearing difficulties may not produce visible symptoms, so screening helps identify potential problems that might otherwise go unnoticed.
Hearing Supports Speech Development: Babies learn to communicate partly by listening to and imitating the sounds around them. Hearing difficulties can therefore affect speech and language development.
Hearing Supports Broader Development: Hearing difficulties can also affect areas beyond communication, including learning, social interaction, and emotional well-being. Identifying concerns early helps you support your child with hearing loss.
What Philippine Law Says About Newborn Hearing Screening
The Universal Newborn Hearing Screening and Intervention Act of 2009 (Republic Act No. 9709) establishes requirements for newborn hearing screening and follow-up in the Philippines.
Screening Prior to Hospital Discharge: Newborns must be screened for hearing loss before discharge, unless parents decline on religious or cultural grounds. Parents who decline must sign a written waiver acknowledging their responsibility to screen and the risks involved. This waiver becomes part of the newborn’s medical record.
Screening After Non-Hospital Births: Babies born outside hospitals must be screened within the first three months.
Follow-Up After Screening: A full diagnostic evaluation must follow in time for intervention before the child turns six months old. This evaluation must be conducted by a Newborn Hearing Screening Center certified by the Department of Health (DOH).
Types of Newborn Hearing Tests in the Philippines
Two common newborn hearing tests in the Philippines check different parts of the hearing system.
1. Otoacoustic Emissions (OAE)
A tiny plug with a microphone is placed in the baby’s ear to play sounds and record the ear’s response. If no emissions are detected, this may indicate hearing loss.
2. Auditory Brainstem Response (ABR)
Small wires or sensors are attached to the baby’s scalp while they sleep. Clicking sounds are played through tiny earphones, and the test measures the baby’s brain response to these sounds.
When Should Newborn Hearing Screening Be Done?
The DOH follows a 1-3-6 approach to newborn hearing screening:
Within the First Month: Complete newborn hearing screening, ideally on or after 24 hours of life and within the first month.
Within One to Three Months: If the baby does not pass the initial screening, complete a follow-up hearing evaluation within one to three months.
By the Sixth Month: Early intervention should begin, with hearing aid fitting and hearing and behavioral rehabilitation recommended within six to twelve months of age.
What Happens If a Newborn Does Not Pass the Hearing Test?
The newborn hearing tests are designed to detect hearing issues early and are generally accurate. However, no test is perfect, so false-positive and false-negative results can occur.
If your baby receives a “refer” or positive result on their newborn hearing screening, it does not by itself confirm permanent hearing loss. The next step is follow-up testing to determine whether further evaluation is needed.
In the Philippines, the Department of Health recommends follow-up testing with both ears re-evaluated even if only one ear received a refer result. If the result remains concerning, complete an audiologic diagnostic evaluation in time for appropriate follow-up and intervention before six months of age.
Book a Hearing Screening at Hear Life PH
Newborn hearing screening gives you an early opportunity to learn more about your baby’s hearing and understand whether further assessment may be needed. If your child was not screened as a newborn, you can still assess hearing later as they grow.
At Hear Life PH, our audiologists can perform hearing tests in the Philippines for children around 3 years old and up at selected branches using conditioned play audiometry. For children under 3 years old, we offer other tests at our Main Office in Manila, usually by appointment. Where hearing aids are recommended, we can recommend suitable Widex hearing aids based on your child’s hearing needs.
