Overview of the Marpac Dohm Sound Machine

Marpac Dohm Sound Machine

Classic Design

Measuring at 5.8 x 5.8 diameter and 3.8 inches tall, the Marpac Dohm sound machine features the original design that the company first released for its white noise machines.

It is also very light, weighing only 2 pounds, and has only one button, the power switch.

Single Power Source

It’s the best setup in the nursery to help babies sleep.

The Marpac Dohm Classic sound machine is powered by a 6-foot 120V AC plug and uses 18 watts.

More Natural Sound

What produces the white noises in the Marpac Dohm Classic is not just a replaying of fan sounds, but an ACTUAL built-in internal fan!

You get real fan sounds from the actual wind blowing that it manually makes that also acts as a sound conditioner to block noise.

Two White Noise Settings

Because the Marpac Dohm Classic fan sounds are mechanical, it isn’t equipped with a speaker and produces only one sound — the fan sound (and no other ambient sound).

However, you can choose between the two fan speeds that SOUND DIFFERENT.

It produces mid to moderate frequency, and the loudness and tone can also be slightly adjusted to your preferences.

Superior to a Real Fan

So if Marpac Dohm sound machines are basically just small fans that are encased, how is it any different from an actual fan?

First of all, the Marpac Dohm sound machine produces LESS AIR than an actual fan.

Since it is made as a sound machine, it does NOT blow air your way like a regular fan and make you feel cold.

The Marpac Dohm does NOT trigger dust allergies either by stirring up dust in the air as a fan would.

And of course, it lets you fall asleep better because its natural fan sounds are MORE SOOTHING to the ears.


  • Natural sounds
  • Actual fan installed, not just a recording
  • Adjustable tone and fan speeds


  • Not much of blocker of outside sounds due to the volume limit
  • No timer

What Is White Noise?

White noise is the sound that contains ALL frequencies perceptible to the human ear.

It ranges from 20 to 20,000 hertz and is played at the same volume. These frequencies have an equal distribution of energy and intensity.

This equal distribution at the same volume then creates a humming sound.

Its equal intensity also masks the loud sounds around you that could disturb your sleep.

White noise is STEADY and CONSISTENT. Examples of white noises are humming air conditioners or an oscillating fan.

You can take advantage of this noise to create a more peaceful and soundproof bedroom!

How About Pink and Brown Noises?

Let’s start with Pink:

Pink Noise

Pink noise is DEEPER and contains MORE BASS sounds than white noise.

Like white noise, pink also contains all the frequencies humans can hear, but the energy distribution is UNEQUAL.

This results in lower frequency being more powerful, resulting in a MORE RESONANT sound.

Pink noises are what we hear in nature, like an ocean sound, soft rain, or the steady wind blowing.

Brown Noise

Brown noise is the DEEPEST out of the 3 noise colors since it contains high energy in low frequency.

This is what you hear when it’s raining heavily and thunder strikes without warning.

LectroFan vs Marpac Dohm: Comparing the Features

Both sound machines are great and have their own set of strengths, but which one has the strengths you actually need?

#1 Portability

If you are a frequent traveler (especially overseas), you should definitely go for the LectroFan sleep machine.

Its ability to run on different voltages, the inclusion of AC adapters and USB port, and the rechargeable feature will make your masking noise during all your travels super convenient!

And as if that’s not enough, this sound machine from Adaptive Sound Technologies is also small enough to fit in your hand!

Meanwhile, the Marpac sleep machine is larger, heavier, has no battery option, and can not run on other voltages.

But if you will only need a sound machine for home or office use and will hardly move it around or travel with it overseas, then the Marpac Dohm is a great machine for your needs.

SIDE NOTE: Bringing either machine for traveling might be too much for some. We recommend using noise-cancelling earmuffs instead for more convenience.

#2 White Noise Sound Profiles

Do you prefer a mechanical sound or a variety of recorded sound profiles?

The Marpac Dohm goes above and beyond the regular fan sound that most sleep machines offer since it’s not just a sound. The sleep machines themselves are actual fans blowing actual wind.

Your soothing sounds can’t get more natural than that!

The only downside its sound has is that it only produces 1 sound at 2 speeds.

Some even say it has 2 white noise sounds since the high-speed option does sound DIFFERENT from the low-speed option.

The LectroFan, on the other hand, is just a machine that plays recorded soothing noises.

But it makes up for it by giving you so much more tracks to choose from.

You get 10 fan sounds plus 10 ambient noises, including pink and brown noises!

#3 Volume

Since the sleep machines from Marpac only produce one sound, the loudness range is also very limited.

It can only reach moderate volume even at its loudest setting and might not be as helpful when you have very loud neighbors.

In comparison, the LectroFan boasts of a larger frequency range and up to 85 dB when set at its maximum volume, enough to cover up ALL the usual loud disturbances in your surroundings.

Frequently Asked Questions

Now let’s answer some of the questions you might be curious about:

How Many Decibels Is a LectroFan?

The LectroFan can go as high as 85 dB, enough to mask sound from your loud environment, such as traffic noise or barking dogs.

Which LectroFan Model Is the Best?

The LectroFan Micro is a good alternative. It’s smaller, more travel-friendly, and has Bluetooth speakers and a built-in microphone.

It also has 5 fan tracks, 4 white noises, and even 1 ocean surf track!

Are Marpac and Dohm the Same?


Marpac company has merged with YogaSleep, and the popular white noise machines are now called Marpac Dohm.

How Loud Is the Marpac Dohm?

The sound range of the Marpac Dohm is between 50-75 dB at a single speed.

Final Verdict: Which of These White Noise Machines Are Better?

Both the LectroFan and Marpac deserve the top spot of the best white noise machines — it’s just that they are basically in different categories.

The Marpac is an actual fan, while LectroFan plays recorded tracks.

Because of this, the Marpac produces a more soothing, natural sound. It also cannot mask outside sound as well as the LectroFan.

The LectroFan offers more flexibility in adjusting pitch and sound and offers WAY MORE available tracks.

It is also designed for travelers, while Marpac is meant to sit in one place.

In the end, you’re the judge for which is the better sound machine.

  • Which of the two will fit your lifestyle best?
  • What kinds of noises do you prefer listening to?
  • Which one are you already taking a liking to?

Whichever fits your needs and preferences wins the crown since both machines are top quality and are the best in their respective categories.
