How loud should the white noise be for it to be effective but safe?
Last updated on April 1, 2026
In the studies showing that white noise improves sleep, they operate the noise at a decibel level of 70 to 75, which is below the levels of concern. In addition, these studies tend to focus on the value of noise in falling asleep. Given this, a first step is to try to generate a level of 70 to 75 decibels for the white noise you use. If you are still concerned that it’s too high, the second step would be to turn it down once the baby is asleep. You can use a decibel level-measuring app to measure the decibel level of the machine and adjust it accordingly.
