In case you missed it, May was National Speech-Language and Hearing Month, with the goal of raising awareness about communication disorders and promotes services that support speech, language, and hearing health. Millions of Americans experience communication challenges, and early intervention by professionals like audiologists and speech-language pathologists can significantly improve outcomes across all ages.
In early childhood—especially infancy—auditory input is essential for speech and language development. Recent research has begun to explore how modern parenting tools, such as white noise machines, may impact infants’ auditory development.
A study published in JAMA Pediatrics, along with other follow-up research, has raised concerns about the risks of prolonged or improper use of infant sound machines. These devices, used to promote sleep, emit white noise or calming sounds that mask background noise. However, some machines produce sound levels exceeding safe decibel thresholds, potentially posing a risk of noise-induced hearing loss if placed too closely or used for extended durations.
The American Academy of Pediatrics and the American Speech-Language-Hearing Association recommend the following:
Recommendations for Safe Use of Sound Machines for Infants
1. Placement: Keep the device at least 7 feet away from the infant’s crib.
2. Volume: Set volume at the lowest effective level, ideally at or below 50 dB SPL A.
3. Duration: Use the machine only as long as needed, avoiding continuous overnight use. Utilize any built-in timer features.
Parents can use the NIOSH Sound Level Meter App for a more reliable and accessible way to measure sound levels when a specialist-calibrated meter isn’t available.
Dr. Ashley Brindley, Au.D., Audiologist at Coryell Health, shares:
“White noise machines can be helpful for soothing infants, but it’s important to use them responsibly. Early hearing experiences are foundational for speech and language development. By following safety guidelines, parents can protect their child’s hearing while still supporting healthy sleep habits.”
With proper use and guidance from audiology professionals, white noise machines can be a safe, effective sleep aid for infants—without compromising long-term hearing and communication outcomes.
