Technical Committee: Room and Building Acoustics (TC-RBA)
The Technical Committee Room and Building Acoustics (TC-RBA) will provide all colleagues in the field of room and building acoustics an information platform about new activities, research results, papers, books, congresses, projects, workshops etc.
A major task of the committee is to stimulate joint activities and mutual worldwide co-operations between researchers and related Technical Committees, such as the Technical Committee on Architectural Acoustics (TCAA) of the Acoustical Society of America (ASA), to initiate common projects in research, development, and education, and to help in organizing structured session in Room and Building Acoustics for congresses, especially for the Forum Acusticum every third year. Every year there will be symposium or similar meeting arranged by the TC-RBA, and the intention is to alternate between room acoustic topics and building acoustic topics. Collaboration has been established with the CIB WG 51 Acoustics, that the meetings on building acoustics are arranged as a joint meeting for TC-RBA.
The web page of the EAA will serve as a convenient tool for exchanging such information and for establishing contacts, discussion and collaboration. All colleagues, who are working in the field of Room and Building Acoustics, are kindly invited to participate in these activities and to post contributions. The TC Room and Building Acoustics will become more living and useful the more colleagues from all over Europe will send their contributions.
The last meeting of the TC Room and Building Acoustics was held on 17th September 2004 in Guimarães, Portugal. (Minutes of the meeting of TC-RBA in 2004).
A number of Working Groups have been established to deal with special topics (see below). Members that are interested in contributing to a WG are invited to contact the person in charge.
From 1994 to 2002 there has been arranged three series of Round Robin for evaluation of room acoustic prediction models. This work has been conducted by PTB in Braunschweig, Germany. Detailed information is available, both concerning the results and concerning the room input data, which means that these three room examples may also be used in the future for testing the prediction capabilities of new room acoustic software and/or the users of such software.

An open database for loudspeakers has been established April 2005. This will be useful in connection with room acoustic prediction models. The CLF (Common Loudspeaker Format) Group has agreed to support a common format, making loudspeaker data easier to supply and use. Thus loudspeaker performance and polar data are now available in an open and secure format. (Link: http://www.clfgroup.org/index.htm)
For the next future, the following activities are planned:
- Meeting of the technical committee TC-RBA in connection with Forum Acusticum in Budapest, Monday 29th August 2005.
- A round table discussion about evaluation methods for sound insulation organised by WG 4 during Forum Acusticum in Budapest, Thursday 1st September 2005.
- A 4th Round Robin on room acoustic prediction models with emphasis on auralisation will be started after Forum Acusticum in Budapest.
- A symposium on building acoustics joint with CIB WG 51 Acoustics, to be held in 2006. The time and place to be announced later.
- A symposium on room acoustics as a satellite symposium either before or after the ICA 2007 in Madrid, Spain.
