Limón

Limón is the capital city and main hub of Limón province, as well as of the cantón (county) of Limón in Costa Rica. It has a populace of about 60,000 (including surrounding towns), and is home to a booming Afro-Caribbean community. Part of the community traces its roots to Jamaican laborers who worked on a late 19th railroad project that connected San José to Puerto Limón. 

Other parts of the population trace their roots to the Panamanian, Nicaraguan and Colombian turtle-hunters who ultimately settled along the Province of Limón's coast. Until 1948, the Costa Rican government did not recognize Afro-Caribbean people as citizens and controlled their movement outside Limón province. Accordingly of this “travel ban”, this Afro-Caribbean population became firmly established in the region, which affected the decision to not move even after it was lawfully allowed. The Afro-Caribbean community speaks Spanish and Limonese Creole, a creole of English.

White Noise

White noise is a kind of noise that is generated by combining sounds of all different frequencies jointly. In case you took all of the possible tones that a human can hear and combined them collectively, you would have white noise. 

The adjective “white” is used to illustrate this type of noise owing to the way white light works. White light is made up of all of the different colors (frequencies) of light combined together (a prism or a rainbow separates white light back into its component colors). Likewise, white noise is a blend of all the different frequencies of sound. You can believe of white noise as 20,000 tones all playing at the same time.
