From the Research
The recommended decibel level for sound machines used with newborn babies should not exceed 45 decibels, as recommended by the American Academy of Pediatrics, to avoid any potential hearing damage. This limit is crucial because newborns have sensitive hearing systems that are still developing, and exposure to louder sounds can potentially cause hearing damage. Sound machines should be placed at a distance from the baby's crib, and parents should use the lowest volume setting that effectively masks environmental noise. The evidence from the most recent study 1 suggests that reducing sound levels to 45 dB or less can promote growth and reduce adverse neonatal outcomes. It is essential to prioritize the safety and well-being of newborn babies by minimizing their exposure to loud noises.
Some key considerations for using sound machines with newborn babies include:
- Placing the sound machine at a safe distance from the baby's crib
- Using the lowest volume setting that effectively masks environmental noise
- Avoiding continuous use throughout the night
- Considering the use of a timer feature that automatically turns off the machine after the baby falls asleep
- Testing the volume of the sound machine before regular use to ensure it is within safe levels
The evidence from studies 2, 3, and 4 highlights the importance of minimizing noise exposure in newborn babies to prevent potential hearing damage and other adverse effects. However, the most recent and highest-quality study 1 provides the strongest evidence for recommending a decibel level of 45 dB or less. By following these guidelines, parents and caregivers can help ensure the safe and healthy development of newborn babies.
