How White Noise Machines Work

A white noise machine is a device designed to produce a consistent, soothing sound that helps mask other environmental noises. This can aid in relaxation, sleep, concentration, and even reducing the perception of tinnitus. Here’s a closer look at what white noise machines are, how they work, and their benefits:

How White Noise Machines Work
White noise machines generate sound that contains equal intensity at different frequencies, creating a uniform auditory signal. This type of sound can mask background noises by blending different frequencies together, making it difficult to distinguish individual sounds. This effect can be particularly useful for:

- **Privacy:** In offices or medical settings, white noise can help maintain confidentiality by masking conversations.
