Dohm DS White Noise Machine Review

We’ve owned a few copies of the Dohm DS white noise machine for two decades. We run them most every night in bedrooms and guest rooms without noticeable harm or any ill effects whatsoever; either to ourselves, or to these sound conditioners.

This Dohm DS white noise machine indeed helps enhance sleep, and fits into most any room décor, with its ivory, off-white color. Thus, it can compliment any color scheme. Indeed, we wish we would have known about these white noise sleep aids years ago, when we relied on much bigger table fans to generate enough white noise to sleep by. The fans, while creating plenty of white noise, also generated much unwanted air currents and drafts. This Dohm DS sleep conditioner however, which itself contains a genuine fan, creates all the white noise but none of the draft. Nice.

We found very little to complain about in the Dohm DS white noise machine. Even the $49.99 price per unit seemed reasonable. Hard to find these units used for much cheaper. It seems that once people buy them, they rarely sell them, running them until they completely wear out. Scarcity on eBay probably means an excellent quality device.  Plus, the mechanical simplicity of this fan-in-a-box, means that it can run and run, for decades, without failing.

Benefits, Pros, Advantages, and Features of the Dohm DS White Noise Machine

Simple to Use

It has a three-position OFF, LOW, and HIGH rocker switch, a top disc adjustment that rotates, and a side ring adjustment that also turns. The latter two settings alter the characteristics of the produced noise to tailor the sound output to most any sleeping situation, room acoustics, types of surrounding noise being blocked, and so on. You just plug in the 980A, turn it on, and rotate the adjustments.

The Dohm DS White Noise Machine has Two Speeds

It has a low speed and high speed setting built into the three-position power switch. The high speed works best for the noisiest slumber environments.

Vibration Isolation

The DS features a foam rubber pad on its bottom to provide some isolation from the surface that you sit it on. This keeps humming noise and 120 Hz. vibration from the AC motor inside pretty low.

Compact Design

Much smaller and lighter than the fans we used before purchasing the DS SleepMate. So it’s much easier to find room for it close to the bed. Its modest size also makes the Dohm DS quite portable, so you can benefit from its calming white noise sound while traveling as well as in your bedroom at home.

Does Not Collect Much Dust

Unlike the fans that attracted much dust over time, this DS noise machine does not collect much dirt as there’s effectively no air movement through the unit. The blades inside are fashioned to make noise, not to move air (and dust) around.

Neutral Colors

Its light ivory, black, or gray color (comes in these three colors) makes the DS machine go well with most any room color scheme.

Several Units Strengthen the Effect

The Dohm DS blocks otherwise intruding noise pretty well for moderately quiet environments. However, we have extremely sensitive ears. For us, just one DS therefore, was insufficient. So we bought several others to place around the bed for a stereo white noise effect that worked much better.

The Dohm DS White Noise Machine has No Looping Effect

The Dohm DS white noise machine has dual speeds. Plus, it has a real motor and fan blades inside, that create a very steady, non-varying white noise that features low hum and vibration sound, and has no “loop effect.” Often the digital sound conditioners play a three or five second long sample over and over again. Call us strange, but we indeed hear that looping when trying to sleep, and so, it agitates and irritates. Thus the digital units end up keeping us awake; having the opposite of their intended effect.

The Dohm DS offers about the best white noise sound of any white noise devices we’ve tried. We prefer its electro-mechanical fan sound over the more modern, digital sound conditioners because the DS creates a fuller, virtually non repetitive whirring noise, whereas the digital ones generally have a “tinny” sound that lacks low-frequency content; an essential component of effective white noise; particularly when needed to combat the lower frequency sounds of traffic and footfalls.

The Dohm on the other hand, just emits a gentle air-blowing sound that blocks external mid-range and high-frequency noises very well, and it does a pretty good job masking the lower frequency sounds (bumps in the night, slamming doors, television bass, cars going over rumble strips outside, and so on).

Great for the Office

The Dohm DS white noise machine works well at the office also.  It lessens the impact of sudden noises often heard in close spaced cubes.  Friends say that having used these truly fan-based sleep machines for thirty years, with health improvements noted (they sleep sounder with them, and are thus more alert and energetic at work, experience improved mood, are less irritable, able to focus and concentrate more, and are generally more healthy overall). Indeed, we’ve found the Dohm DS highly effective at, “cancelling,” or at least, covering up distracting noises such as televisions playing in adjacent rooms, laughing and conversations, the cats jumping from high places and thumping around, and traffic noises outside.

The Marpac SleepMate Tradition Lives On

We find it in this Dohm DS sleep sound generator.  This unit virtually duplicates the performance and function of the Marpac 980A SleepMate of years ago.

Disadvantages, Problems, Cons, and Limitations of the Dohm DS White Noise Conditioner

As mentioned, we found none too much to legitimately gripe about in the Dohm DS  SleepMate. But here are several minor complaints we have.

Not Loud Enough

Particularly in close living quarters with neighbors.  There, very thin walls are the order of the day. Thus, we had to buy three of them; not just one.

Not Enough Bass

It does not block very low frequency thud style noises very well. We wish Dohm would consider designing a much bigger unit that generates a much louder low-frequency component in the white noise. This would better cover the jolting thumps of footfalls above, and door slams below.

We Often Hear Hum 

This model provides insufficient vibration isolation; We can hear the motor humming unless we fold an undershirt and put that between the DSand the supporting table.

Not Maintenance Free

The motor bearings inside need oil now and then; particularly when used every night for several years as we use ours. No big deal however, as a motor disassembly is not too challenging, and the bearings (both top and bottom) can be cleaned and lubricated with a few drops of silicone machine oil.

Our Rating on the Dohm DS White Noise Sound Conditioner

The Dohm DS white noise machine is a good value. It lacks none of the features or simplicity anticipated from a truly great, easy to use white noise machine, though perhaps some of them could be improved a little. Nonetheless however, we would again buy the DS, and would therefore rate this unit at 98 out of 100.

Where to Buy the Dohm DS Sound Screen Conditioner

These devices are available online at Amazon, eBay, and other Internet vendors. Some retail brick-and-mortar places carry them as well, although we’ve not seen them sold locally.
