What Is a White Noise Machine?

Many people casually refer to any ambient background sound as white noise. But white noise actually has a specific definition in terms of the frequency and amplitude of the sound waves.

Frequency refers to the speed of a sound wave, or how many waves occur per second. Amplitude refers to the power of the sound wave, or the height of each wave. You can think of frequency as pitch and amplitude as volume.

White noise is a collection of sound waves that contain every sound frequency audible to humans at the same amplitude. The result is a consistent, gentle hum or whirring noise similar to the static of an untuned radio.

A white noise machine is designed to create soothing ambient noise, which can be an important tool for improving your bedroom environment.

Although some models may have an option for true white noise, many white noise machines actually produce a different color of sound known as pink noise. Unlike white noise, pink noise uses lower frequencies. Many nature sounds such as ocean waves fall under the category of pink noise.

How to Find the Best White Noise Machine For You

When shopping for a white noise machine, you should consider your personal preferences and how you plan to use the device.

  • Sound: Different white noise machines come with different sound options. Certain models may be limited to a single white noise sound, while others contain a variety of pre-recorded nature sounds.
  • Volume: It’s important to make sure that the white noise isn’t too quiet or too loud. Most models have a minimum of two or three volume settings, but if your volume preferences change from night to night, you may want to look for a white noise machine that allows for a wider range of volumes with fine control.
  • Display: A well-designed display makes it easy to control your white noise machine. However, a display that’s too bright may do more harm than good in terms of promoting sleep. Consider a model with an intuitive yet dimly lit display, or one that has the option to turn off any built-in lights. Alternatively, look for a model that includes a clock or nightlight function that can be toggled on and off.
  • Timers: If you enjoy white noise as you fall asleep but don’t want it to play all night, choose a model that comes with a built-in timer. This allows you to program the white noise machine so it shuts off after a set amount of time.
  • Portability: The familiar sound of your white noise machine can make it easier to fall asleep in a new environment. When comparing models, consider size and portability, especially if you travel frequently.
  • Smart Features: Some white noise machine models can integrate with your smartphone, allowing you to control your device remotely and access more advanced controls and programming options.

Types of White Noise Machines

White noise machines come in many styles, each with its own set of features. It’s helpful to understand the different models available in order to find the best white noise machine for your needs.

Bedroom White Noise Machines
A bedroom white noise machine is the most standard type. These machines are typically analog and come with several options for different sounds and volume levels. A bedroom white noise machine might fit well on your bedside table, but it probably won’t include advanced controls or smartphone integration, and it may not be portable.

Smart Alarms
Smart alarms are designed to fulfill several functions in addition to being an alarm clock. For example, some smart alarms include programmable white noise options as well as alarm clock and nightlight functions. You can usually access these functions using a smartphone app.

Travel White Noise Machines
This style of white noise machine is designed for portability. Travel white noise machines are much smaller than standard bedside models and more minimal in terms of sound and volume features. However, they often include a micro USB rechargeable battery so you can run the device without a power outlet.

White Noise Machines for Children
Some white noise machines are designed with babies and young children in mind. These models have special features to give parents extra control over their child’s sleep environment. Features can include child-friendly sounds, a portable design, a nightlight, timed shut-off, and smartphone integration for remote control.

Why Should You Use a White Noise Machine?

White noise machines create ambient background sounds that can be beneficial for many activities and environments. For example, the comforting hum of white noise can help boost your focus while reading, studying, or meditating.

Gentle white noise can also help you fall asleep faster and stay asleep. And if you share a bed, a white noise machine may reduce the impact of distracting sounds like a partner’s snoring.

If you live in a large city, near a busy street, or in a space filled with family, kids, or roommates, a white noise machine can be handy for drowning out the commotion. However, white noise can also be helpful for those who have tinnitus or simply prefer light background noise to silence.

How Does Noise Affect Sleep?

If you’ve ever tried to fall asleep in a noisy environment, you know that sound has a profound impact on sleep. Leading health organizations like the NIH and the WHO recognize that excess environmental noise causes sleep disturbances and is a major public health concern.

Too much background noise can disrupt sleep in several key ways. A noisy environment makes it more difficult to fall asleep. You’re also more likely to be startled awake during the night. The result is interrupted sleep and less total sleep time.

Adequate high-quality sleep is imperative for good health. Insufficient sleep can lead to daytime sleepiness as well as a wide range of long-term health effects including depression, diabetes, obesity, and cardiovascular disease.

However, not all sounds in the bedroom are bad. White noise can help drown out disrupting background noise. And there’s some evidence that the masking effect of white noise can  improve sleep.
