What to Consider When Buying a White Noise Machine
The popularity of these handy devices means there are lots of models with a range of features on the market. No need to lose sleep over selecting the best white noise machine for your needs. Keep reading to learn how to navigate the selection.
White noise machines rarely exceed 7 inches in width, length, or height. Heavier models weigh 12 to 15 ounces, while lighter ones weigh 5 to 6 ounces. White noise machines designed for travel are smaller and lighter than models intended for stationary use.
Before buying a white noise machine, decide how and where you are going to use it. If you live a nomadic lifestyle or have a tiny nightstand, a smaller model may be the best white noise machine for you. If your device will never move from your bedroom dresser, size may not matter as much.
The best sound machine for you will be largely based on the different sound modes each unit offers.
Type of Sound
White noise machines differ widely in the types of sounds they offer. Some stick to nondescript white noise. Some machines use pink noise—which is deeper than white noise—or natural sounds like ocean waves, rainfall, rustling leaves, and waterfalls. Some models also offer machine sounds like washers, electric fans, or air conditioning units, and everyday ambient soundscapes like muted chatter or traffic sounds. Before choosing a white noise machine, decide if white noise is what you need to catch some Z’s, or if the lullaby of Mother Nature would do a better job of helping you get to sleep.
Your noise machine shouldn’t be too loud. You want to drown out distractions, but the machine’s white noise shouldn’t go above 50 decibels. Some white noise machines can reach up to 85 decibels, which is over OSHA’s limit for eight hours of safe noise exposure. You can still buy a white noise machine that can be set loud, but be mindful of how long you turn the volume up.
Some white noise machine models put their sounds on a loop for a continuous listening experience. That means they’ll hit the end of a recording and begin again in a smooth transition. Be sure you get a model with a clean loop. On the other hand, if repetitions will distract you, look for a device with a non-looping feature.
Some machines come with an app that lets you add your own sounds or music that you can control with your smartphone. You can adjust the volume, timer, or sound mode with a touch on your screen. Some brands have integrated sensors to detect auditory distractions and automatically adjust the volume accordingly.
Baby-friendly sound machines may also incorporate additional smart features, like a two-way audio monitor and compatibility with Alexa or Google Home for hands-free control.
Smart-tech features can bump up the price, so decide if you need them before paying extra for them.
Some white noise machines double as an alarm clock or light. If you don’t have a bedside lamp, or you need as much help waking up as you do falling asleep, those features might be worth the extra cost.
Other features you can find in white noise machines include headphone ports, Bluetooth accessibility, and a timer for pre-set operation. Devices are powered by batteries, electrical outlets, USB cords, or some combination of those sources.
