Room Acoustics
Data is displayed for academic year: 2023./2024.
Course Description
Sound propagation in closed spaces. Influence of shape and volume on acoustical properties of room. Objective and subjective parameters of acoustical quality of a room. Methods for evaluation of acoustical quality of rooms. Acoustical elements: absorbers, diffusers and reflectors. Design of acoustical elements. Calculation of basic acoustical parameters of rooms. Computer simulations of acoustical properties of rooms. Acoustical requirements for typical rooms (classrooms, theaters, concert halls, multipurpose halls). Measurements of objective parameters of acoustical quality of rooms. Subjective evaluation of acoustical quality of rooms. Auralization.

Forms of Teaching
Lectures
The theory behind the room acoustical phenomena is explained. These phenomena are also explained through demonstrations, where applicable.
ExercisesCalculation tasks based on theory are solved in class.
Independent assignmentsThe students are required to write an essay on a topic of choice, within the scope of the course. As the task of the final project, the students need to choose a room and design the acoustics inside using any kind of room acoustics simulation software, following all the demands and guidelines with respect to the size and the purpose of the chosen space.
LaboratoryThe students are acquainted with the design, measurement and evaluation techniques used in room acoustics, and are motivated to use them by working in small groups.
