White Noise Evolution: From SleepMate to Dohm

Posted by Molly Szkotak on September 25, 2018

 

Some of you may be surprised to learn that the Marpac Dohm wasn't always the Dohm. But, like all good things, our iconic Dohm white noise machine has evolved over the years. Invented by our founder J.K. Buckwalter in 1962, the “sleep-inducing sound-producing device” was originally dubbed the SleepMate, and marketed as a natural sleep tool to “cover up all those nerve-wracking noises with a breezy continuing SWOOSH.” The SleepMate (or Sleep-Mate) was formally submitted for a patent in 1963, and nearly 6 million units have sold over the decades, thanks in part to being popular in gift catalogs like Hammacher Schlemmer.

In 2010, we decided it was time for us to adapt to changing times, so we gave the SleepMate a newer and more contemporary name. Our hard-working sleep machine giving it a mini-makeover without touching any of its patented inner workings or features. With a little inspiration taken from yoga, the SleepMate became the Dohm (just saying the name is relaxing!)
