Why this tool is useful
Brown noise, also called Brownian noise or red noise, has even more low-frequency energy than pink noise, producing a deep bass-heavy rumble similar to strong thunder, ocean waves, or the interior sound of an aircraft at cruising altitude. Many people with attention disorders report that the deep predictable sound of brown noise significantly reduces distractibility during focused work sessions. Brown noise is a popular focus-aid tool with millions streaming it daily for improved concentration and deep work.
