If you’ve ever had difficulty sleeping, you’ve probably heard of or used white noise. But did you know pink noise also exists? Well, it does and has been getting a lot of research attention lately. You may be asking yourself now, what is this pink noise? Pink noise refers to signals or sounds with a frequency spectrum. It is used to refer to any noise that has a power spectral density which takes the form of:
S(f)a1/ f a, where f is the frequency and a lies between 0 and 2.
The pink noise can be achieved naturally from natural sources. Some examples are a Rain storm, Waterfalls and Waves crashing on the beach. Pink noise is different from white noise in that, the frequency increases while the power per hertz decreases, with white noise, the power per hertz is equal throughout all frequencies.
How it can help an exercise workout, happiness and health
Pink noises are best known to improve one’s sleeping time, especially for the elders. Example of pink noise is the sound of a waterfall. The noises exhibit a rhythm through their rise and falls which are synchronized to the rhythms of the brain waves often slow than those that occur during sleep time. The pink noise will increase ones time spent in a deep sleep since they refresh the slow-wave sleep and they consequently improve one's memory. The health of the brain is thus boosted by the innovative simple and safe non-medication approach. This is a potential tool that could be adopted for boosting memories among the elderly thereby reducing memory decline relating to age.
The pink noise facilitates slow-wave sleep which is beneficial given that this type of sleep is associated with reduced diabetes, stroke or related other heart diseases. Nearly all the diseases that are fatal have a cause which links to one not having a good sleep. Therefore, improving one's sleep can help reduce the risk of getting these diseases.
When it comes to exercise and workout, the pink noises are known to boost one’s effort to reduce weight and stay in shape. This is because the deep satisfying sleep experienced by the individual will allow the body to function efficiently and thus one's intention in the mind will smoothly be fulfilled.
Where to get pink noise
Pink noises have previously been discovered from statistical fluctuations of extraordinary biological and physical systems. Fluctuations in tides, heartbeats, quasar light emissions, river heights and firings of single neurons are among the areas where pink noises are produced.
Electronic devices may be used to produce pink noises in form of MP3. Compression of MP3 creates long pink noise files which will assist in filtering the high-frequency energy. The main source of pink noises within the electronic devices involves the slow fluctuations of condensed materials of the electronic tools. The sources of the fluctuations will include the fluctuating occupancies of traps in semiconductors or the fluctuating configurations of defect metals. With the advancement of technology, there has been an innovation of pink noise applications that may be installed on mobile phones.
