This white noise machine is powered by a fan and delivers a genuine white noise experience, not a recorded one that gets played back to you. You can adjust the volume and tone for a custom sound.
The Dohm Classic (White) Original White Noise Machine has a fan that generates noise but no air so as not to disturb you or your pet. The power cord is sturdy to avoid getting knocked out of the wall accidentally by your dog. The motor may fail over time and the volume may not get loud enough to block out louder sounds, like an AC unit.
