How to Buy a White Noise Machine

White noise machines help people sleep. These small devices mask out unwanted sounds such as voices, cars, trains and other unwelcome noise. Some devices offer ambient sounds like the calming effects of an ocean, rain or a breeze. Others with pure white noise masking adjust airflow through the device, canceling out noise. Decide on the type you need before you shop.

Instructions

1. Look at the types of white noise machines based on what sounds and features they have.

2. Consider a pure white noise machine that masks all sounds. This type is both a market standard and popular.

3. Examine machines that filter various volumes of sound. These devices, called pink noise, mask like white noise machines but with a different quality of sound.

4. Buy an ambient sound-masking machine that provides calming sounds. Popular listening features include ocean surf, rain, wind and general nature sounds. White noise still masks unwanted sounds while you listen to these other selections.

5. Purchase a white noise machine that has volume controls in case you want more or less masking. Mechanical machines have only one consistent volume, while electronic machines offer more control.

6. Determine the price you want to pay for your masking machine. Prices vary, so shop around. Midrange prices or higher provide the best solutions for pleasant sleeping.

7. Check out options for features you need. Some have portable capabilities with both plug and battery operations. Consider a machine with a timer if you don't want it to run all night.

Tips & Warnings

• Even with the several choices for white noise machines available, the pure white noise machines rank as the best in effectiveness for sleep.

• Many popular machines function by having a fan push air outward through slots. These have an adjustable dial on top that you turn either upward or downward. These various settings produce different masking abilities through the outward movement of air.

• An average white noise machine fits easily on any nightstand. They typically measure 6 inches in diameter and about 3 inches in height with a weight ranging from 1 to 2 lb.
