Editorial Acústica e Vibrações 50

Abstract

Editorial

The Editorial Committee of Revista Acústica e Vibrações presents the commemorative Edition n°50 with great satisfaction. It brings several news for authors and readers, that is, innovations for the magazine and articles it contains.

Internationalization is important for scientific and technical journals, promoting access to content by a wider audience. Thus, seeking internationalization for A&V, the first page of each article will act as the identification of the work/article. It will contain, in addition to the title, names, affiliations, abstract and keywords, also (the new fields) PACS, title, abstract and keywords.

As a novelty, still on the first page, there will be a unique identification code, the so-called DOI (Digital Object Identifier), with the article being registered in an international database, facilitating access so that it can be found on the internet. As a result, more access is expected and the articles are more cited.

The file templates (templates) for writing new articles were renewed, and versions for writing in Latex and Ms Word are now available. They are available both on the Sobrac website and on the Overleaf_ The instructions were all rewritten, contemplating writing and formatting rules. With this, the styles are standardized, making the submissions already in the final format of the article. From this number onwards, bibliographic references are numbered (as permitted by Brazilian regulations).

The complete digital magazine (in PDF), now contains clickable links and bookmarks, making navigation easier. All articles open on the right, so eventually some blank pages appear in the full issue.

With the aforementioned updates, Revista Acústica e Vibrações has its layout similar to the major magazines in the field, such as the Journal of the Acoustical Society of America it's the Journal of Sound and Vibration.

A&V is, as we know, a gathering magazine covering several areas of knowledge. In this issue we bring seven articles, organized in an order in which some connection with the consequent is sought.

The first article is about building a head tracking device using hardware low-cost. Next, there is an article with the use of artificial neural networks for the application in virtual acoustics, also using HRTFs.

Still employing a lot of signal processing, the third article presents “Comparative results for Room 10 of Round Robin 4 obtained by the computer code RAIOS 7”, clarifying the scenarios and showing the objective parameters obtained. In the fourth article, we explore the use of microphone arrays for in situ of acoustic impedance, a parameter of notable importance in computational acoustics.

In the fifth article, the magazine goes in the direction of building systems and architecture, presenting the “influence of filling ceramic blocks with expanded vermiculite” for walls, including experimental aspects and relevant results.

The sixth article bridges the gap between architecture and virtual models for simulation, discussing geometry details and simulation results. Finally, the last article (not least) brings the “noise map as a diagnostic and design tool”, highlighting regulatory aspects and examining results.

After the technical articles, there are still some elements at the end of this issue. The first one is the model article, entitled “Instructions and article model for Revista Acústica e Vibrações (2018–2021)”, which can be used as a guide for authors.

Next, there are the calls: join Sobrac (with information for new people interested in joining), special call for the 12th Iberoamerican Congress of Acoustics - FIA 2020 together with the XXIX Sobrac Meeting (which will be held in Florianópolis, SC) and a dedicated section with a nice list of “acoustic congresses around the world”, listing dates, venues and websites. Finally, the issue closes with a brief description of the process of creating the commemorative cover of this issue.

It is very important to thank the Sobrac Board of Directors for the invitation, the authors and the group of reviewers, for their hard and beautiful work, essential to make this publication a reality.

Cordially,

Prof. Dr. William D'Andrea Fonseca
