In your workplace, you don’t want anything too loud or rhythmic, but the sound of softly blowing air can do the trick— it is subtle, but very effective. White noise is designed to be as unnoticeable as possible. The sound doesn’t contain distracting patterns, and you won’t have changes in the volume unless you switch the low and high settings yourself. In a short period of time, most people come to consider white noise as a natural part of their environment. Low and steady sounds in the background become generally accepted as normal pretty quickly. A consistent background sound provided by "good noise" allows you to focus because you won't be noticing the "bad noises" made by coughing coworkers and clanking office machines nearly as much as you do now.
A white noise machine can also provide privacy when you are talking on the phone or have a client or vendor at your desk. Coworkers in the next cubicle, or those just walking by your desk, won't be able to distinguish your words very easily or plainly. After all, no one needs Nosey Nellie gossiping about what she thinks you said to your doctor, spouse, or best client. When office privacy walls aren't possible or in the budget where you work, an inexpensive white noise machine can allow you to concentrate better and have more private conversations both in person or while on the telephone. And if you have trouble sleeping due to unwanted noises, try a white noise machine at your home, too!
