Foundations: Sound, Frequency, and Brainwaves

Describe the perceptual qualities and common examples of white, pink, and brown noise.

Create a simple guide for when to use each noise color for focus, relaxation, or sleep, with listening examples.

Explain the mechanism of binaural beats and how they are used to target specific brainwave states (beta, alpha, theta, delta).

Describe the historical context and commonly attributed effects of solfeggio frequencies.

Critically assess the scientific evidence for the effectiveness of binaural beats and solfeggio frequencies to inform curation choices.
