The perception of color in light and the perception of sound are fundamentally different processes. The mixing of different colors of light can result in white light, whereas the mixing of different sound waves does not create an equivalent perception of "white sound."
The perception of color in light is based on the additive color mixing model. In this model, colors are created by combining different wavelengths of light. The primary colors in this model are red, green, and blue, often referred to as RGB. When red, green, and blue light are combined at full intensity, they stimulate the three types of color receptors (cones) in our eyes, which are sensitive to different ranges of wavelengths. The combined stimulation of these cones results in the perception of white light.
On the other hand, sound waves are characterized by their frequency or pitch. Mixing different sound waves of varying frequencies does not result in the perception of "white sound" or any equivalent concept. Instead, the combination of sound waves leads to complex interference patterns and interactions, which result in a different perception of sound, such as a combination of pitches, harmonies, or dissonances.
Furthermore, the perception of sound involves different mechanisms in the auditory system compared to the perception of color in the visual system. Our ears detect sound waves and transmit them to the brain, which processes and interprets the information. The perception of sound is based on the analysis of different frequency components, their relationships, and temporal patterns.
In summary, the mixing of different colors of light can create white light due to the additive nature of color perception. However, the mixing of different sound waves does not generate an equivalent phenomenon because the perception of sound is based on the analysis of frequency components rather than additive color mixing.
