Multifunctional acoustic unit and its acoustic potentials dependence on material structure
* Presenting author
Abstract:
The following research relates to an acoustic unit used to construct acoustic building walls for improving the acoustic environment in music schools, concert halls, home cinemas, recording studios, offices, restaurants and alike. In order to have an optimal acoustical environment it is necessary to have two acoustical elements namely: the sound diffusion property and sound absorption property, particularly in a balanced manner.Therefore, it is an object of the research to suggest an acoustic unit which overcomes or at least greatly reduces the disadvantages known from the mentioned type that is to say an inexpensive acoustic unit which exhibits both: sound diffusion, sound insulation and absorption properties and furthermore has excellent fire resistance performance. A further object is to provide an acoustic unit particularly capable of adjusting the sound absorption property after the installation.
