Vol. 23 No. 39 (2008): Acústica e Vibrações 39

Editorial

Eight technical articles were submitted for issue 39 of the Acústica e Vibrações, all of them through the Sobrac website, which made the assembly of the magazine less laborious. It is quite true that not all articles were entirely in the format. Some present color figures where the color clearly lends quality to the information in the article, but unfortunately the cost of color prints is known to be high, and they were printed in black and grayscale.

The journal still does not have an editorial committee that reviews the submitted articles, and thus all were accepted. In issue 38 of Acústica e Vibrações, an interview was published with two personalities of the Society about the magazine. We hope that in 2009 we will be able to start the Forum on the Acústica e Vibrações magazine.

The interview in this issue is with Professor Ieda Russo and deals with various issues related to the area of ​​acoustics and speech therapy.

The number 39 of Acústica e Vibrações is also available on the Sobrac website, with the figures in color. We hope you like it and as soon as the Forum goes live, participate and send suggestions about the desired profile for our magazine.
