Many people have heard of white noise but few have a really, good understanding of what it is and why it is used. White noise in simple terms is a combination of all frequencies of sound audible to the human ear blended together. (Just as white light is composed of all frequencies of light). White noise sounds like a hiss, similar to radio static or the sound of rushing air when traveling by airplane.

Although there are many uses for white noise, we often see corporations using a white noise machine or system to “quiet” a department. For instance, if a company had a department full of computer operators, all clicking away at the keyboard, the sound would become overwhelming and distractive. The same would be true for a customer service department with employees all talking to customers on the phone. By using a white noise generator, sound is greatly minimized.

Millions of people around the globe struggle with getting a good night’s rest. For some, the problem is environmental, such as rooms that are too light, uncomfortable bedding etc. while for others it is merely a problem of tuning out the day’s events. Regardless, a white noise generator produces a sound that is calming. While perfect for everyone, people who work nights and sleep during the day or those in large, noisy cities, really benefit from a white noise machine by being able to block outside traffic and other unwanted sounds.

Okay, so how do white noise generators work? Random sound frequencies are produced in order to blend with the unwanted environmental noises in order to essentially mask them. The special sound created is one to three decibels above a normal conversational voice, which actually makes it nearly impossible for a human being to realize when white noise is being used. Additionally, white noise machines generate random audible frequencies that are distributed equally over the entire range of human hearing, which is what allows them to be so effective.

You will also find white noise machines used in unique situations. For new parents, getting a full night’s sleep is rare. The calming sound of white noise can often help your baby to sleep better. There are many types of sound conditioner on the market today some of which can also produce natural sounds such as waterfalls, surf, or even simulate a mother’s beating heart. Some sound conditioners offer five, ten, or more options of natural sound combined with white noise in order to create a soothing and relaxing environment that is conducive for sleep. Also, white noise generators offer a portable and compact privacy solution. Most machines are volume adjustable, and best of all, they are an easy and affordable remedy to an otherwise noisy problem.

There are many different companies that sell white noise machines. Be sure you purchase your machine from a reputable company, one that can guide you to the appropriate size and type that is suitable for your needs.
