The city of the event

Ouro Preto: história viva entre montanhas

Cercada pelas montanhas de Minas Gerais, Ouro Preto é um verdadeiro mergulho na história do Brasil. Reconhecida como UNESCO Patrimônio Cultural Mundial, a cidade preserva o maior conjunto homogêneo de arquitetura barroca do país e encanta visitantes com suas ruas de pedra, igrejas imponentes e paisagens que parecem ter parado no tempo.

No auge do Ciclo do Ouro, entre os séculos XVII e XVIII, Ouro Preto foi um dos principais centros econômicos do mundo. A riqueza que brotava das minas transformou a antiga Vila Rica em palco de intensa efervescência cultural, artística e política. Foi ali que surgiram movimentos que ajudaram a moldar a história do Brasil, como a Inconfidência Mineira.

Com o declínio da mineração, a cidade preservou seu patrimônio arquitetônico e cultural, mantendo viva a atmosfera histórica que hoje a torna única. Caminhar por Ouro Preto é como fazer uma viagem no tempo — cada ladeira, cada praça e cada construção carregam memórias de um dos períodos mais marcantes do país.

Além de sua relevância histórica, Ouro Preto também pulsa cultura, arte e gastronomia. Museus, ateliês, festivais e a tradicional culinária mineira completam a experiência de quem visita a cidade.

Mais do que um destino, Ouro Preto é cenário perfeito para encontros inspiradores, trocas relevantes e experiências memoráveis.

Atrativos Turísticos

Igrejas, são mais de 20 igrejas com uma riqueza inigualável e belíssimas obras dos artistas Aleijadinho e Mestre Ataíde); museus, entre os mais importantes estão o Museu da Inconfidência, A Casa do Contos e o museu do Oratório; parques; minas de ouro; mirantes; cachoeiras; trem turístico, entre outros.

Patrimônio Cultural Protegido

A riqueza cultural de Ouro Preto vai muito além de suas construções históricas. Ela está presente nas tradições, nos modos de viver, nas manifestações artísticas e na memória preservada ao longo de gerações.

No Brasil, a Constituição Federal de 1988 estabelece que o Patrimônio Cultural inclui bens materiais e imateriais que representam a identidade e a história da sociedade. Isso significa que tanto monumentos e edificações quanto saberes, celebrações, expressões artísticas e práticas culturais fazem parte dessa herança coletiva.

Para garantir a preservação desse patrimônio, existem instrumentos como inventários, registros, tombamentos e outras medidas de proteção, que asseguram que esses bens continuem sendo valorizados e transmitidos às futuras gerações.

Entre os exemplos de Patrimônio Cultural estão: formas de expressão artística e cultural; modos de criar, fazer e viver de diferentes comunidades; criações científicas, artísticas e tecnológicas; obras, objetos, documentos e edificações históricas; conjuntos urbanos e sítios de valor histórico, paisagístico, artístico, arqueológico e ambiental.

A proteção do patrimônio é uma responsabilidade compartilhada entre o poder público e a sociedade. Esse trabalho garante que a história, a identidade e a beleza de Ouro Preto permaneçam vivas, permitindo que moradores e visitantes vivenciem uma cidade que preserva o passado enquanto se conecta com o presente.

IV CACS


The Conrado Silva Acoustics Student Competition (CACS) was created in 2017 with the objective of stimulating the interest of undergraduate students in the area of acoustics, encouraging technical quality, creativity and innovation in acoustic-architectural solutions.

The contest is an important action for the training of human resources, for encouraging scientific initiation and for the development of design thinking based on acoustic performance.

CACS honors Professor Conrado Jorge Silva de Marco, a prominent historical figure in Brazilian Acoustics, recognized for his pioneering performance and for his unique trajectory of articulation between the fields of music and acoustics. Professor Conrado Silva has worked as a professor at the University of Brasília (UnB), São Paulo State University (Unesp), Santa Marcelina College and São Paulo School of Fine Arts, in addition to having coordinated the Latin American Courses of Contemporary Music.

Previous editions of the Conrado Silva Student Competition (CACS) addressed the following topics:

  • I CACS: " Multipurpose Room" (Porto Alegre, 2018);

  • II CACS: "Architectural party based on acoustic performance" (Florianópolis, 2022); e

  • III CACS: "Acoustic quality of the school space: emphasis on learning environments" (Natal, 2023).

With the IV CACS, Sobrac aims to contribute to the awakening of attention to acoustics among undergraduate students, in addition to encouraging technical quality, creativity and innovation in acoustic-architectural solutions to the proposed problem. Therefore, the objective is to contribute to the consolidation of the importance of the multiple interfaces of acoustics in the academic community.

THEME: Reacoustic qualification of historic buildings

The IV Conrado Silva Acoustics Student Competition will have as its object of intervention the Diamantina Room, located at the Arts and Convention Center of the Federal University of Ouro Preto (UFOP), in the municipality of Ouro Preto, MG.

The UFOP Arts and Convention Center, inaugurated on March 21, 2001, results from the revitalization of the old Augusto Barbosa Metallurgical Park, built in 1946, configuring a relevant experience of requalification of an industrial complex for academic, scientific, cultural and tourist purposes.

The building is located in the protection perimeter of the Architectural and Urban Complex of Ouro Preto, of recognized historical, artistic and urban relevance. Due to this insertion, the proposals must observe the principles of preservation of cultural heritage, ensuring compatibility between the proposed intervention and the existing architectural context.

Acoustic & Vibrations Hackathon 2026


O Hackathon Acústica & Vibrations 2026 will be an intensive, collaborative and interdisciplinary activity, lasting 24 to 48 hours, involving undergraduate and graduate students, researchers and professionals in the fields of acoustics, vibrations, engineering, architecture and related fields. This is the first edition of a Hackathon within the scope of the events organized by SOBRAC, representing an innovation in the traditional format of the Meeting, with a focus on Acoustics and Vibrations applied to Heritage History.

The activity is an initiative of the Young Acousticians Network Brazil (YAN-BR) in partnership with Sobrac, and aims to develop innovative solutions applied to acoustics and vibrations in heritage assets, which may involve software, algorithms, analysis methods, data visualizations, monitoring strategies, intervention proposals or conceptual products.

The participating teams will receive mentoring from experts from academia and the productive sector, promoting the approximation between science, technology, innovation and concrete demands of society.
