Função logarítmica: uma proposta de aula aplicada no estudo do som

Abstract

The study on screen has the central scope of proposing a didactic sequence on aspects of learning the logarithmic function, as well as characterizing it, presenting examples of its use and discussing its practical application in the study of sound. An important element in the world of mathematics, the logarithm gains relevance due to its practicality and ease of simplifying the calculation. The methodology used was bibliographical research, with a qualitative approach. It is expected that the results achieved can signal how the logarithmic function has a wide range of applications, not only with the study of sound, but also in other applications such as cooling a body, earthquake scaling, carbon-14 dating, decay radioactive, population growth, hydrogen potential scale, continuous interest, musical scales, atmospheric pressure, Newcomb-Benford Law, sensory perception, among others. Key-words: Mathematics; logarithmic function; learning.
