Acústica para el siglo XXI Acoustics for the 21st Century

摘要

Acoustics is one of the older branches of the physics and because of that many physicists think that there is no more acoustic science to develop and that the acousticians are presently playing only a technical role. This is a view that, if admissible for certain sectors of acoustics as for other sectors of physics, is completely erroneous referring to a so wide-ranging discipline. In fact, acoustics as the science of elastic waves should be considered as a parallel field to that of the electromag-netic waves and both are very open and active scientific and technological areas. It would be a very pretentious and risky task to foresee the future of the acoustics for the 21st Century, as the title of this lecture suggests. Such title has been taken from the am-bitious motto of the ICA2007MADRID, but this lecture only will try to offer a contribution to the perspectives of the acoustics for the following years bearing in mind the main emergent topics which presently focus the attention of the acousticians.
