Marpac signature sound

You may already know that we’re the original sound machine.  You may also know that we’ve been around for over 50 years, and are beloved by generations of passionate fans.  But do you know just what it is that makes our sound machines so special?

Well, without giving away ALL of our secrets, let’s just say that it’s in the construction. True, our machines are built to last, but our real claim to fame is the unique quality of our sound. This isn’t your average “white noise” - our Dohm produces a sound we call “Marpac Signature Sound.”  It’s a true natural white noise produced by a real fan housed inside a specially designed adjustable acoustic shell.  This mouthful means that the soothing sound is continuously generated - no digital loops or recordings here!  Unlike a regular fan, however, the Dohm is fully adjustable in terms of tone and volume, and also lacks the airflow, allergy, drying, portability, and rattling concerns commonly associated with fan use.

Here’s what people have to say about our soothing sound:

It produces the same white noise as the fan did, but not the dryness. It has been 2 weeks and we are sold. I have sleeping very soundly and not waking up in the middle of the night. It has changed my life. Totally worth the investment. Highly recommend this if you have trouble sleeping and staying asleep.


I tried just using a fan for white noise for way too long but I would always wake up with an extremely dry throat, plus it never seemed to make enough noise to block everything out. I wish I would have bought this a long time ago.


The white noise is loud and very effective at drowning out background sounds, and the volume is adjustable to suit your preference. It's the effect of having a fan in the room, but without the cold air freezing you out in the winter time!

I tried blasting a fan which did work but wasn't practical. And traveling has always been an issue because I can't cart around a giant box fan. I tried another sleep machine that had feedback and just didn't have the steady stream of white noise that I need. But this one does! The sound is so soothing and is just one flow of noise that doesn't fluctuate.


Our non-Dohm sound machines are constructed differently, but with the same attention to detail and devotion to quality. Getting as close as possible to “Marpac Signature Sound” through the use of high-quality components and exacting engineering is always our goal.
