Resumo: This thesis aims at measuring room impulse responses with a spherical microphone array. The array consists of 32 microphones distributed throughout the surface of a rigid sphere. The text brings the methodology used to design the spherical microphone array and its application in real case scenarios. Impulsive responses were simulated for some room configurations and measured in two real rooms. The signals acquired with the spherical array were processed with conventional beamforming an energy analysis of directional impulsive responses. The results show the array’s capacity to detect the sound sources and wall reflections in both simulated and measured environments. An energy analysis shows, through a spherical grid, what are the directions of the remaining energy in the room.

O arranjo é composto por 32 microfones distribuídos ao longo da superfície de uma esfera rígida. O texto traz a metodologia utilizada para a confecção da esfera de microfone. As respostas impulsivas foram simuladas para algumas configurações de salas e medidas em dois ambientes. O processamento dos sinais foi realizado através da técnica de beamforming e análise energética das respostas impulsivas direcionais. Os resultados mostram a capacidade do arranjo em detectar as fontes sonoras e as reflexões que ocorrem nos ambientes medidos e simulados. A análise energética mostra através de um grid esférico quais as direções de chegada da energporUniversidade Federal de Santa MariaCentro de TecnologiaPrograma de Pós-Graduação em Engenharia CivilUFSMBrasilEngenharia CivilAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessResposta impulsivaArranjo de microfonesImpulse responseMicrophone arrayBeamformingCNPQ::ENGENHARIAS::ENGENHARIA CIVILDesenvolvimento de arranjo esférico de microfones e sua aplicação na medição da resposta espacial de salasDevelopment of spherical microphones arrayand their application in the use of the spatial rooms responseinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisCarneiro, Eric Brandãohttp://lattes.cnpq.br/2876372207029481Fonseca, William D'Andreahttp://lattes.cnpq.br/1677987461176747Masiero, Bruno SanchesGomes, Marcio Henrique de Avelarhttp://lattes.cnpq.br/7425298232154767Deboni, Guilherme Corrêa30010000000360060060060060060079f516f9-8d92-4175-816a-516f667b958c41263f1d-4e7d-4d97-af7a-0185c02f25647fe845c5-fc5f-4c42-beff-8dc8e8bf90700a1058b5-66e4-4d26-b722-7a3ad903874d102d6c23-bf33-470a-87fd-11a5c94f6cacreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGEC_2020_DEBONI_GUILHERME.pdfDIS_PPGEC_2020_DEBONI_GUILHERME.pdfDissertação de Mestradoapplication/pdf71109253http://repositorio.ufsm.br/bitstream/1/22235/1/DIS_PPGEC_2020_DEBONI_GUILHERME.pdffbf28663fe7373e6f98e11647ba8f1aaMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
