![]() If the track is short, it lacks variety, and if the looping isn’t done well, you’ll notice a break in the sound or a strange underlying pattern. The quality of such a machine depends on the track length and how seamless the looping works. Typically these machines also have their white noises and fan sounds as pre-recorded sounds. At the end of the track, the machine loops, i.e., restarts the track. When you choose the sound “ocean waves,” the machine plays the pre-recorded track “ocean waves” from its memory card. These include sounds like rainfall, ocean surf, brook, fire place, waterfall, train ride, and so on.Ĭurrent budget nature sound machines (at least the ones I have come across) are similar to MP3 players that play sound samples on repeat. ![]() These machines are attractive if you want the soothing sound of a real fan to help you relax and fall asleep, but don’t want that fan to cool down your room.īecause these machines aren’t as adjustable for volume and frequency range as electronic white noise machines, they don’t block nearly as much environmental noise. Machines with a real fanįan-based machines contain a motor and a real fan inside their housing, but are designed to prevent airflow and the stirring up of dust. ![]() So if you only need white noises and fan sounds, you can get a better product for your money by buying a machine that specializes in these sounds. The problem is that in virtually all budget machines that offer nature sounds and white noises, the white noises are recorded and generally worse than in dedicated white noise machines. You might think, “I want white noises, but I am getting one that also offers nature sounds, just in case.” This review points out which machines fit the bill. The advantage is that you won’t hear patterns or breaks in these non-repeating sounds as you could with short sound recordings on repeat. If you don’t need nature sounds, I recommend you get a machine that dynamically generates white noises and fans using electronics rather than playing a recording. White noise machines that focus on white noises and fan soundsĮlectronic white noise machines with a good selection of white noises and a good volume and frequency range are very effective at blocking environmental noises such as barking, speech, traffic noise, crickets, etc.
