This issue has an article, an insert and information about the X Meeting of Sobrac, held in December 1989 in Rio de Janeiro/RJ; XII World Congress on Occupational Health, held in May 1990 in Hamburg (Germany); and Internoise 89, held in December 1989 in Newport Beach (United States of America).

The article written by Elvira Viveiros presents the implementation of a quick method for evaluating the acoustic intelligibility of rooms.

Finally, the booklet has a mini-class on vibration isolation.

Editorial

Sobrac, despite the difficulties that the country is going through, has grown a lot, but it needs to grow much more, for its strengthening and development of acoustics and vibration science. During the 88/89 administration we managed to hold a meeting in Florianópolis-SC, at the end of 87, another in Campinas-SP, at the end of 88, as well as, together with the Rio de Janeiro Regional (Roberto Tenenbaum, Moyses Zindeluk, Jules S. Slama and Ricardo Musafir), the extraordinary III International Seminar on Noise Control, in December 1989 in Rio de Janeiro-RJ, also mentioning the replacement of the newsletter by Revista da Sobrac, published from 1988 onwards on a biannual basis . We also managed to consolidate our connection with the International Institute for Noise Control (I/INCE), in addition to continuing our efforts to hold an “InterNoise Conference” in Brazil, as we are competing in the queue for 93. We wish you a happy and fruitful management for the new Board of Directors for the 90/91 biennium, and we make our acquired experience available to those who will further enhance Sobrac with their greed, creativity and willingness to work.
