The name white noise comes from the analogy to white light, which contains the whole spectrum of colors of light.
White noise is similar to the sound of the rain, a rumbling waterfall, rustling leaves, a fan or a static TV. White noise can also be produced digitally or it can come in form of so called white noise machines, which are physical devices that produce white noise.
Listening to white noise through your headphones can effectively block out your co-workers and any other annoying noises in order to restore your privacy and create an environment of peace and calm where you can focus on your tasks.
