Resumo: The audio record with acceptable quality of video records, which will be used in research on teaching and learning processes in the classroom, presents itself as a major obstacle to educational research. In this paper, we present a apparated aimed at minimizing this difficulty - the microphone boundary based on pressure zone microphone by Crow (PZM). We describe how to build it further explained yet how to build a preamplifier to amplify the microphone signal and also a source regulated to provide the power of these apparatus. The recordings obtained with this equipment have a much higher quality than those obtained with conventional microphones empowering investigations which use this type of record.

Nesse trabalho, apresentamos um aparatado que visa minimizar essa dificuldade – o microfone boundary baseado no microfone de zona de pressão Crow (PZM). Descrevemos como construí-lo, além disso, explicamos ainda como montar um pré-amplificador para ampliar o sinal do microfone e, também, uma fonte regulada para prover a alimentação desses aparatos. As gravações obtidas com esses equipamentos apresentam uma qualidade bastante superior às obtidas com os microfones convencionais, potencializando as investigações que se valem desse tipo de registro.Imprensa Universitária - UFSC2016-09-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2016v33n2p64110.5007/2175-7941.2016v33n2p641Caderno Brasileiro de Ensino de Física; v. 33 n. 2 (2016); 641-6662175-79411677-2334reponame:Caderno Brasileiro de Ensino de Física (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2016v33n2p641/32334Copyright (c) 2016 Caderno Brasileiro de Ensino de Físicainfo:eu-repo/semantics/openAccessBellucco, AlexCordeiro Marcondes, David William2020-01-06T10:27:22Zoai:periodicos.ufsc.br:article/41071Revistahttp://www.periodicos.ufsc.br/index.php/fisicaPUBhttps://periodicos.ufsc.br/index.php/fisica/oaicbefisica@gmail.com||fscccef@fsc.ufsc.br|| cbefisica@gmail.com2175-79411677-2334opendoar:2020-01-06T10:27:22Caderno Brasileiro de Ensino de Física (Online) - Universidade Federal de Santa Catarina (UFSC)false
