White Noise Machines
In recent years, white noise machines have become a common household item. By playing a constant, low-frequency noise, this device is designed to mask background distractions and create a calming environment.
The theory behind this is that humans are constantly surrounded by certain noises, which distract from an individual’s focus. Playing the noise of a fan or waterfall allows people to concentrate on their work or sleep better because they are not constantly distracted by outside noises.
