Vol. 28 No. 45 (2013): Acústica e Vibrações 45

Editorial

The Editorial Committee of Revista Acústica e Vibrações, issue n°45, presents to the Scientific Community a group of articles that are plural in their theme, but equitable in their quality and importance, which demonstrates the wide scope of the area of ​​Acoustics and Vibrations.

For the composition of the magazine, articles were carefully analyzed and topics were selected that deal from aeronautical noise to urban noise, with emphasis on metropolitan transport and the impact resulting from pumping installations. There is also a concern with the inclusion of professionals in Acoustics and related areas in activities related to Sustainable Development and in the study of classrooms intended for the teaching of Music. The passive control of vibrations and the identification of sound sources by genetic algorithms complete the topics covered in the texts.

The details and deadlines for submitting papers for the XXV SOBRAC Meeting, which will be held from October 20 to 22, 2014, in Campinas/SP, as well as information about the Workshop supported by SOBRAC's North Region complete this 45th Edition from the Journal of the Brazilian Acoustic Society.

The editors thank everyone who submitted their work and hope to receive new contributions for the next editions of Revista Acústica e Vibrações.
