Sound waves are fluctuations in air movement, similar to waves in water, and they are captured by the ear and processed by the brain to make sense of the environment.

Your cochlea acts as a prism, breaking down sounds into different frequencies, allowing the brain to interpret them accurately.

Binaural beats involve playing different sound frequencies in each ear, which the brain averages to create an intermediate frequency that can enhance focus and learning.

Low-frequency sounds, like delta waves, can aid in transitioning to sleep, while higher frequencies, like beta waves, are beneficial for focus and sustained thought.

While binaural beats can help some people learn better, low-level white noise may be more effective for enhancing learning by modulating brain chemistry.

There is evidence that white noise during development can be detrimental to the auditory system, disrupting the formation of tonotopic maps essential for processing sound frequencies, although it doesn't necessarily disrupt speech patterns permanently.

It's not advisable to expose a child to white noise throughout the night, as it may degrade the clarity of their auditory tonotopic maps, potentially affecting their learning and development.

Once the auditory system has established tonotopic maps, background white noise at a low volume shouldn't pose a problem for learning, as it can support a heightened state of alertness and dopamine activation.
