The science behind pink noise

Pink noise is a sound frequency that humans can hear, often used as background or control noise to block out outside distractions.

Emphasizes lower frequencies compared to white noise and can be less distracting than other types of noise.

Researchers have focused on a softer version called “pink noise,” which has become popular due in part to experiments with improving sleep memory using this type of frequency.

Differences between pink and white noise

White noise contains the same energy per frequency band, making the higher frequencies more prominent, while pink noise resembles natural sounds like waterfalls or rain because it has the same energy per octave, which which gives more emphasis to the lower frequencies.

Applications of the pink sound in research

  • Treatment of hearing disorders: Exposure to specific levels of pink noise can help treat hearing disorders such as tinnitus by stimulating the auditory system without causing discomfort or discomfort (source).
  • Sleep improvement: Low decibel levels of pink sound while you sleep can improve memory consolidation, potentially increasing cognitive performance (source).
  • Sound masking: Pink noise is often used in sound machines and white noise generators to create a consistent background noise that can help mask disturbing sounds, such as traffic or noisy neighbors, due to its balanced frequency distribution (source).

Pink noise can be a beneficial aid to those looking to improve their sleep and cognitive abilities, making it an invaluable resource.

Benefits of using pink noise to sleep

Listening to pink noise can block out annoying background sounds without making them sound harsh or shrill, potentially boosting memory and allowing for better quality restful sleep.

Popular sleep apps that include pink noise options

Popular sleep apps that include pink noise options include Sleepy Sounds, Sleepo – Relaxing Sounds, Sleep, Pzizz – Sleep, Nap, Focus, and White Noise Lite.
