Sound masking is the addition of a familiar sounding, air conditioning-like background sound to an environment. Masking covers up or “masks” human speech and helps mitigate the distraction of other sounds, making an environment more comfortable, workers more productive and creating speech privacy. Here’s an analogy. Imagine that you are in a darkened room and a child is flicking a flashlight on and off. The light is noticeable and distracting. Now imagine, the lights are on. The same flashlight is being flicked on and off—but without notice—it has been “masked.” This is how sound masking works.
