White Noise and Its Noise Masking Properties
In recent years, the productivity of white collar industries has declined at a rate inversely proportionate to the expansion of its labor force. It has been noted that office density may be at the root of the problem. Simply put, there are more workers per square foot of office space today, resulting in overcrowding. With so many workers in such small spaces, much interference is generated by office interruptions. These interruptions usually result from noise generated by employee conversations and office equipment. As such, the above-mentioned problems from office density lie in the increasing noise density. In effect, the growth of the white collar work force has reached a tipping point in which this growth is creating the decline of productivity, rather than an increase.
One way to stave off the disruptions generated by office noise is to utilize white noise; a form of noise that has more to do with wavelengths than with the color white itself. It is a combination of multiple sound frequencies emitted across one stream, similar to how white light is the light which results from the absorption of multiple light frequencies.
As such, when it is broadcast loudly enough, white noise can conceal much of the noise pollution around it by absorbing the properties of sound into its own mix of frequencies. It can serve as an effective panacea against various forms of noise pollution such as humming workstations, idle chit chat, ringing telephones and street traffic and is frequently used to alleviate the emotion and physical stress from these noises.
In recent decades, there has been surge of popularity in white noise machines, which have proven to be very useful within the office environment. They provide a calm and soothing respite from the noise pollution which pervades many an office space and have proven to help increase productivity. They are also used out of the office to help people sleep at night without interruption.
Because the flat spectrum of true "white noise" is actually quite annoying, the kinds of sound generated by these devices is typically much more targeted and can range from the soothing natural sounds of a waterfall and/or birds chirping to those of man-made objects such as distant trains and radio static. As such, there are a broad range of machines that can be chosen to suit one's preference and help reduce noise-related stress.
