With the development of technology and industrialization, problems that haven't been solved in the past have become more easily solvable. The artificial intelligence (AI) field has emerged by starting to apply the working mechanism of the human brain in various ways in computers. With the use and widespread use of AI techniques, solutions to problems in every area of the scientific world are presented. In this work, fuzzy logic (FL) which is one of the techniques of AI is considered. Using the FL, the lighting system in the common areas of the libraries modeled in a sound-sensitive manner.
