Supervisor:

Department of Architectural Engineering

Synopsis:

This course is freely related to the course „Experimental methods in building and room acoustics“, but it focuses on calculation prediction methods of acoustic properties of buildings.

Requirements:

Basic theoretical knowledge of acoustics acquired in one of the other courses on building acoustics.

Syllabus of lectures:

Sound insulation in buildings

- airborne sound insulation of single and double structures

- impact sound insulation of floors

- airborne sound insulation between rooms

- impact sound insulation between rooms

- airborne sound insulation against outdoor sound

Noise from building technical equipment

- sound pressure level in reverberant sound field in a room

Room acoustics

- sound absorption coefficient

- reverberation time

Syllabus of tutorials:

Sound insulation in buildings

- airborne sound insulation of single and double structures (Technical method, B. H. Sharp, J. H. Rindel, INSUL)

- impact sound insulation of floors (Technical method, J. H. Rindel, INSUL)

- airborne sound insulation between rooms (ČSN EN ISO 12354-1, BASTIAN)

- impact sound insulation between rooms (ČSN EN ISO 12354-2, BASTIAN)

- airborne sound insulation against outdoor sound (ČSN EN ISO 12354-3, BASTIAN)

Noise from building technical equipment

- sound pressure level in reverberant sound field in a room (ČSN EN ISO 12354-5, ODEON)

Room acoustics

- sound absorption coefficient (ZORBA)

- reverberation time (ČSN EN ISO 12354-6, ODEON)

Study Objective:

The main goal of the course is to acquaint students with calculation methods which are used for advanced predictions of acoustic properties of building elements, buildings and sound sources, usually during the project planning phase. Students will acquire enhanced theoretical knowledge of sound insulation in buildings, noise from service equipment and room acoustics, allowing them to understand problems related to building and room acoustics and to be used further in their Ph.D. thesis.
