Accustics and music: a methodological approach to explore sounds emitted by sound pipes

Abstract

The present article describes a workshop with Physics students, in which the assembly of a mobile was proposed, by using sound pipes to pursue sound  characterization  and  an  approach  to  the  Physic s principles involved in acoustic phenomena. The comparison between the sounds emitted  by  the  mobile  and  musical  instruments  was  possible through aural  perception  exercises.  Besides,  measurements  were  carried  out using virtual and digital tuners; such results have been compared with the  results  from  Mathematical  Modelling.  The  methodology  used suggests   several   ways  to   teach   the   same   phenomenon,  whose  interdisciplinary characteristic allows one to relate different kinds of knowledge and their application.
