It turns out that using white noise machines to help your kids sleep might not be as harmless as we once thought. A 2024 scoping review found that continuous white noise exposure at moderate intensity during sleep may harm early hearing and cognitive development, especially if used long-term or at high volume. Some machines even clock in above 91 dB, exceeding safety thresholds normally applied to adult workplace noise exposure, definitely too loud for a child’s ears.

According to the American Academy of Pediatrics, everyday noise sources, including white noise machines, can contribute to noise-induced hearing loss, language delays, and learning challenges.
Additionally, researchers at Rutgers University warn that constant monotone sound can disrupt the brain’s formation of “acoustic maps,” which are essential for speech and language development.
In short, using white noise at night is like screen time: helpful in moderation, but harmful when overused.

What Parents Can Do Right Now
If you’re using white noise, here’s how to limit the risk:
-
Volume control is key: Keep it under 50–60 dB—about the level of a quiet conversation.
Parents -
Distance matters: Place the machine at least one foot (30 cm) away from your child’s crib or bed.

Limit runtime: Don’t let the machine run all night. Use it briefly to help your child fall asleep, and consider replacing it with natural soundscapes like heartbeat or ocean waves on a timer.
Why It Adds Up
-
Less EMF exposure supports deeper, healthier sleep and overall brain development.
-
Following volume and placement guidelines helps protect sensitive ears.
-
Embracing alternative soundscapes or timers may preserve the benefits while reducing risk—making it sound safer and smarter.
