Colored Noise, and How It Can Help You Focus

The video explores the concept of color in both visual and auditory contexts, focusing on white, pink, and brown noise. It explains how these noises are composed of different frequencies and how human biology affects our perception of them. White noise contains all audible frequencies, while pink and brown noise adjust these frequencies for a more balanced sound. The video also discusses how these noises can aid concentration and relaxation by masking other sounds, leveraging our evolutionary biology.

What is the main reason white noise is named after the color white?

• Due to the way our ears and brain process sound.

• Because it is played at a higher volume.

• Due to the presence of more low-frequency sounds.

How does pink noise differ from white noise?

• Pink noise has more high-frequency sounds.

• Pink noise balances frequencies to account for human hearing.
