Síntese de som: uma proposta de ensino para funções periódicas

Abstract

This assignment is a bibliographical research that aimed to carry out a study on sound synthesis and develop an educational product in the form of a teaching proposal for periodic functions in High School. More specifically, to present studies of trigonometric functions through activities using applets built in GeoGebra software from mathematical models and the generation of signals that emit a desired acoustic sensation. This proposal intends to instigate the teacher to establish a connection of a supposedly abstract subject with the interactivity and experimentation of the variation of parameters that produces more than a graphic and visual alteration, but that also produces the alteration of the emitted sounds, in order to make the most enjoyable learning. The activities are suggestions that can be reproduced by physics and mathematics teachers without requiring advanced knowledge about sound synthesis, but who are interested in contributing to the teaching of physics, mathematics and their technologies.
