About White Noise & Its Benefits

What is white noise?

White noise is a consistent sound that contains all frequencies our ears can hear, played at equal intensity. It masks sudden changes in sound, creating a soothing background that helps people focus, sleep, or relax.

Who invented it?

The concept of “white noise” comes from early 20th-century physics and signal processing. The term was first used to describe random signals with equal power across frequencies — a concept that later found use in acoustics, electronics, and sleep therapy.

What are the benefits?

Studies have shown that gentle noise can help mask distractions, improve concentration, and even promote deeper sleep. Pink and brown noise, which emphasize lower frequencies, are often described as warmer and more relaxing than pure white noise.

Which type should I use?

It depends on your mood:

  • White noise: balanced and crisp – great for focus.
  • Pink noise: deeper and softer – good for relaxation.
  • Brown noise: deep, rumbling tone – perfect for sleep.
