Why is the Marpac DOHM so popular?
Marpac has been around since the early 1960’s and the fact that this sound machine has been around for more than 50 years (with some revisions of course) means that the DOHM has good roots and has stood the test of time.
The DOHM white noise machine is also the official sound conditioner of the National Sleep Foundation, so it comes with a first class pedigree.
If you suffer from insomnia or have trouble falling asleep, then the Marpac DOHM-DS is the perfect solution for your problems.
One point about the DOHM is that it is a white noise machine, which means that it ONLY plays white noise, it does not play lullabies, rainfall or waterfall sounds.
How does white noise help you to sleep?
White noise is a collection of random sounds between 20 to 20,000Hz and actually is a type of static noise, a hissing sound or some people say it sounds like a whooshing or shushing sound, the wind blowing or a fan/air conditioner.
Just as natural sounds, such as a thunderstorm or a babbling brook can mask external noises, white noise has the same functionality.
So white noise masks sounds which would otherwise keep you awake and stop you falling asleep or wake you from a deep sleep.
What are customers saying about the Marpac DOHM white noise machine?
With more than 9000 customer reviews on Amazon and nearly 90% of them very positive, you can see that the Marpac DOHM is a very popular white noise machine for sleeping. Customers in apartments particularly like the Marpac and soon find that they can’t sleep without it!
Differences between the Marpac DOHM and the Sleep Easy Sound Conditioner
These two sound machines are very similar and customers often try and compare the two, deciding which one to purchase.
So from a functional point of view, there is no noticeable difference between the Sleep Easy and the Marpac DOHM.
Both create white noise only, both run only on mains power and both have a fully adjustable volume and tone, with just an on/off switch and no timer.
The only difference is in the price with the Marpac being twice the price of the Sleep Easy. This may be due to the fact that Marpac has been around for a long time and have a long established reputation.
So it comes down to your personal preference for one white noise machine over the other and your budget. Read the Sleep Easy review here.
What I like about the Marpac DOHM sound machine
The Marpac DOHM is a solid machine with a long and established history for being top quality. Unlike many other sound machines, the Marpac DOHM uses a 2-speed electric motor to create its fan sounds, so the sounds are authentic, but can also be customized.
The volume and tone is fully adjustable and it is ideal for blocking out noisy neighbors, loud AC units, barking dogs, heavy traffic or snoring partners.
Points to Ponder
There is no timer on the Marpac DOHM sound machine, so when you switch it on, it will play all night long until switched off in the morning.
Some people are quite happy with this, but other would prefer a timer and auto-shut off feature.
The Marpac DOHM also only runs on mains power, not batteries, so it is not suitable to take camping, but it is light enough to take on holiday or visiting friends, if you have mains power.
Final Verdict: Is the Marpac sound machine worth it?
This white noise machine is a handy little sound machine, perfect for helping you drift off to a restful sleep, particularly for shift workers who need to mask day time noises, and people who have trouble falling or staying asleep, such as children, students, office workers etc…
The Marpac is on a par with the Sleep Easy Sound Conditioner, but it is around twice the price. Definitely worth a look, if for no other reason than it has a very good reputation with customers.
