After a while, the sound becomes repetitive and if the looping is poorly done, there might even be startling gaps. Note: especially shorter looped recordings annoy some people because the brain learns to make out when the recording restarts. Here are samples of white noises number 1, 3, and 4, which I quite like: īecause the sounds are created on the fly, there are also no loops (as you would have with prerecorded sounds.) The Dohm is for you if you like the sound of a real fan to fall asleep or relax. There are no loops and the sound volume is very stable. Here is how it sounds (best with headphones): Inside its housing spins a real fan and creates a whoosh-sound that escapes together with a little bit of air through multiple openings on the side and on the top. The Marpac Dohm Classic is a fan-based sound conditioner. Devices that play recordings in a loop.Devices that electronically create sound.Machines that contain a fan with a motor that produces sound.I have tested the Marpac Dohm Classic and the Lectrofan, and in this post, I’ll contrast the differences to help you decide which one is right for you.īasically, there are three different types of sound conditioners, aka white noise machines: While similar in popularity, these two are very different sound conditioners, appealing to different people and uses. The Dohm has been made since 1962-and is still being made.
In recent years, the two most popular white noise machines have been the Marpac Dohm and the Lectrofan, now called the Lectrofan Classic.
