What is a white noise machine, and what do they do?

A white noise machine is more than just a collection of ambient sounds such as rain, waves, or rustling leaves.

White noise is a collection of sounds that have the same intensity as the audible range we hear on a daily basis and thus creates a ‘smoothed’ version of uniform sounds which mask loud, disruptive sounds that get in our way when we’re trying to concentrate on other things.

White noise machines are perfect for blocking outside disruptions, aiding concentration and privacy, soothing fussy infants who refuse to sleep as well as aiding natural sleep and can be used in the office or at home.

So, if you’re ready to shut out all that unwanted noise, stick with us, as we take two of the best white noise machines on the market at the moment and put them to the test.

Which one will come out on top? Read on to find out.

Initial thoughts
A white noise machine can be a fabulous addition to your home or office area, and both the Marpac Dohm and the Adaptive Sound Technology (AST) LectroFan two are great examples of good machines that are worth the money.

The basics

Let’s look first at the size and weight of these machines.

LectroFan High Fidelity White Noise Sound Machine

At 5.8 x 5.8 x 3.2 inches and 1.6 pounds, the Marpac Dohm is circular in shape and easily moved all around the home or office to wherever it’s needed.

In comparison, the LectroFan comes in at a larger 11.2 x 11.2 x 5.6 inches, yet lighter at just 1.2 pounds. This means that whilst bulkier, the LectroFan is still an easy enough machine to carry around and transport.

Where power is concerned, both the LectroFan and Marpac Dohm are easily plugged into the AC mains and are supplied with a lengthy cord for optimum placement. This means that there’s no need for batteries: always an added bonus for a machine that’s undoubtedly going to be used for longer periods of time.

Ok, so what’s different then?

One of the greatest differences between these two devices comes from the noises they actually omit.

For instance, the LectroFan offers 10 built-in fan sounds, as well as a further 10 ambient sounds which range from white noise to brown and pink, for a range of calming noises to choose from based on your mood or needed level of distraction.

With the LectroFan, you’ll have more sounds to choose from than you would ever need, making this a fantastic choice to fit a range of situations for the whole family.

The volume of each sound is able to be changed too, based on how much noise you need at any one time, so you’re fully in control.

On the other hand, the Marpac offers instead 2 fan speeds, and no built-in recordings at all, so the level of white noise is different. With these 2 fan speeds, you’re able to adjust the tone and volume to personalize your sound environment in your own way.

This means a little more fiddling around with the Marpac to get your desired sound rhythm, but that is not necessarily a bad point to the machine.

Another initial difference that can be seen between the two machines includes the timer that comes fitted as standard on the LectroFan. The timer can be programmed for up to 60 minutes, which is perfect for bedtime when you hope to fall asleep to the ambient sounds that your white noise machine omits.

Of course, the added benefits to having a timer installed on the LectroFan means that you don’t have to turn the program on manually, and can simply set it to turn on or off at a certain time. It’s just that extra added simplicity that gives you a little more freedom.

It’s unfortunate that this isn’t a feature included in the Marpac Dohm, although it doesn’t make too much of a difference in the grand scheme of things.

Finally, whilst both the Marpac and the LectroFan can be plugged in and charged via AC ports, the LectroFan is also able to be charged up using a USB port, which is a great little extra when so many of our electronic devices rely on USB nowadays. It makes the device even more portable and handy.

Whilst both of these white noise machines are fantastic pieces of equipment with few stand-out differences, for us, the AST LectroFan stands out for the few added extras it has.

With its smaller frame, which uses less power, the added USB charging port as well as the timer function, the fact that the AST has such extra features means that it’s worth those few extra pennies.

As far as the AST being ‘better’ than the Marpac, that’s another story.

Both are fantastic gadgets that each give the desired results they’re designed to create, and they both do that really well, so whilst the AST takes the crown based on the extras it offers, we wouldn’t turn our noses up at the Marpac either.
