Goal:The goal of the course is to familiarize students with the acoustic characteristics of the rooms as well as the possibilities and ways of controlling their acoustic parameters in order to reduce the noise level, ensure the optimal time of reverberation, diffusion, ineligibility of speech and the fullness of the music signal. Acquiring the necessary knowledge for designing sound insulation and acoustic of rooms for various purposes such as: living rooms, classrooms, conference rooms, theaters, concert and cinemas, studios and control rooms.
Outcome:After the course, the students are able to apply the acquired knowledge to design sound insulation and acoustic, as well as settings of various rooms for the preparation, recording and reproduction of audio signals.
