The white noise sounds are too quiet to mask any if the surrounding background noises making it useless for us. Troubleshooting: Please try to raising the volume by turning the top. Keep in mind that this is a sleep sound machine that is a low volume sound to make it easier to sleep and it is not meant to emit high volume sounds.
If the motor sounds like there is something wrong with the machine, you can open the bottom and try to tighten the fan blade.
