They simply repeat, or 'loop,' the same recording over and over again. In this way, the track is unique all the way through.īasic sound machines, however, use looping to create a long track. The best units tend to have long recordings, along with the ability to mix different tracks and add background noises. Sound machines play natural recordings or digitally produced sounds, but the way they do this differs between models. If in doubt, opt for a sound machine that can produce both coloured noise and nature sounds. You can base your sound selection on the types of sounds that you prefer. There are also sound machines that produce both. Some sound machines produce white noise and other colours of noise only, whereas others focus on a range of noises from birdsong to rainfall to ocean waves and more in between. One of the most important features of a sound machine is the selection of sounds it offers. This is particularly useful for people who run their sound machine at bedtime but might be disrupted in the night if the machine were to play continuously. Some sound machines have a timer so you can control how long it will run before automatically switching off. If you often find yourself stressed or tense, a noise machine could benefit you.īestReviews Considerations for selecting a sound machine Timer Sound machines can help office workers concentrate, as they can help block out chatter from neighboring cubicles.Ĭertain sounds may help with meditation and/or simple relaxation. Many people find that sound machines – especially those that produce white noise – can help them fall asleep faster.

Some sound machines are adept at masking other noises, such as the sounds of a construction site or heavy traffic. Notably, sound machines with a fan will only produce white noise and other colours of noise. Some sound machines emit recorded sounds, whereas others have a real fan inside to create a natural sound.

Sound machines either emit noise (white noise, brown noise, or pink noise, etc.) or a range of relaxing recorded sounds such as a rainforest, ocean waves, or crackling fires. If you're not yet well-versed in sound machines, let's learn more about what they're for and some of the reasons why users love them. You've probably heard of white noise, but what about pink, brown, red, blue, green, or purple noise? An entire spectrum of colored noises exist, each with its own range of frequencies and amplitudes.
