Anotace(semestr )
Students will gain cross-cutting knowledge in the field of acoustics of buildings. The course is aimed at explanation and practice of basic topics, but also of extension topics that the building physics specialist or acoustician commonly encounters in building practice.
Obsah 
1. Introduction to acoustics of buildings (basic acoustical terms and quantities, levels and decibels, perception of sound, sound sources and sound fields, noise limits)
2. Outdoor sound propagation (geometrical spreading of sound with a distance, effect of climatic events, ground reflection, diffraction over noise barriers)
3. Indoor sound propagation (direct and reverberant sound field in a room, sound absorption)
4. Airborne sound insulation of single building elements (the effect of composition and installation method on sound reduction index, simplified and detailed calculation methods, practical examples)
5. Airborne sound insulation of double building elements (the effect of composition and installation method on sound reduction index, simplified and detailed calculation methods, practical examples)
6. Impact sound insulation of floors (normalized impact sound pressure level of slabs, the effect of composition and installation method, heavyweight and lightweight floating floors and floor coverings, reduction of the impact sound pressure level, calculation, practical examples)
7. Flanking sound transmission (via structural paths by lateral building elements and via indirect air path) and flanking impact sound transmission (calculation methods, sound insulation requirements between rooms)
8. Noise from building service equipment (sanitary installations, HVAC, elevators), elastic mounting of machines (resonant diagram) and elastic mounting of building structures (staircases, lifts)
9. Airborne sound insulation of building envelopes (sound transmission from outdoor to indoor, sound reduction index of windows, effect of ventilation elements, requirements), building as a stationary sound source (radiation of sound from facades)
10. Room acoustics (optimal reverberation time and acoustic design of selected types of indoor spaces – classrooms and auditoriums, gyms, swimming pool halls, etc.)
11. Sound absorbers (porous and resonant absorbers, hollow resonators), sound reflecting and scattering elements
12. Traffic noise (road as a noise source, calculation method, reduction of traffic noise by urban, technical and organizational measures)
13. Summary (noise control engineering, building acoustics, room acoustics)
