how to test newborn hearing at home

3 min read 31-12-2024

Bringing your newborn home is an exciting time, filled with cuddles, sleepless nights, and a whole lot of love. But amidst the joy, there's a crucial aspect of your baby's health to check: their hearing. While a comprehensive hearing test should be conducted by a healthcare professional, there are simple observations you can make at home to assess your baby's hearing development. This article will guide you through some basic at-home hearing checks and when to seek professional help.

Understanding Newborn Hearing Development

Newborn hearing isn't fully developed at birth. It continues to mature in the first few months. However, early detection of any hearing problems is vital for early intervention and optimal development. Many babies pass their newborn hearing screenings in hospitals, but it's important to remain vigilant and observe your baby's responses to sounds at home.

Simple At-Home Hearing Checks for Newborns

These are not substitutes for professional hearing tests. They are simply observation tools to help you notice potential issues early on.

1. The Startle Reflex (Moro Reflex)

What to do: Make a sudden, but gentle, noise near your baby (not directly in their ear). This could be clapping your hands or shaking a rattle slightly further away.

What to look for: A healthy newborn will usually exhibit a startle reflex, also known as the Moro reflex. This involves a brief widening of the eyes, throwing their arms out and then bringing them back towards the chest. A lack of response could warrant a check-up.

2. Responding to Sounds

What to do: Make various sounds at a distance, such as speaking, singing, or playing music. Observe your baby's reactions. Vary the volume and pitch.

What to look for: As your baby grows, they should start turning their head towards the source of the sound. Initially this will be quite subtle movements. A lack of response or consistently turning away, may indicate a possible hearing problem.

3. Observing Vocalizations

What to do: Pay attention to your baby's own sounds. Are they cooing, gurgling, and making other noises? Does the pitch, loudness, and quality of their cries change?

What to look for: Babies typically begin making sounds in the first few months. A delay or absence of vocalizations can be a red flag, however some babies are quieter than others.

4. Eye Contact

What to do: Engage with your baby, talking and making eye contact. Observe how they react to your presence.

What to look for: Good eye contact shows interaction with a source (you). A lack of engagement or frequent loss of focus, could indicate difficulty perceiving sounds.

When to Seek Professional Help

It’s crucial to remember these home checks are observational; they are not a replacement for professional diagnosis.

Seek immediate medical attention if you notice:

Your baby doesn't respond to loud noises.
Absence of a startle reflex.
Significant delay in vocalizations (no cooing, babbling by 6 months).
Your baby doesn't turn their head towards sounds.
Family history of hearing loss.

Professional Hearing Tests

Your pediatrician or a pediatric audiologist will conduct a thorough hearing test, usually an auditory brainstem response (ABR) or otoacoustic emissions (OAE) test in the first few months.

These tests assess the auditory pathways and can detect even minor hearing impairments. Early detection is key to providing appropriate intervention and maximizing your baby's communication and development.

Conclusion

While these at-home checks can offer some peace of mind, they shouldn’t replace professional medical advice. Regular check-ups with your pediatrician are essential for monitoring your baby's overall health, including their hearing. Early detection of any hearing issues is crucial for optimal development. Don't hesitate to reach out to your healthcare provider if you have any concerns about your baby's hearing.
