Anotace	(semestr )
Within the course, students will acquire theoretical and practical knowledge of selected measurement methods used in the field of architectural acoustics. The experience gained will help them to better understand the topics discussed in the basic acoustics courses and at the same time facilitate their application in building physics practice.
Obsah
1. Introduction (basic acoustic terms and quantities, the importance of measurement in acoustics of buildings) 2. Measurement equipment (measurement microphones, sound analysers, acoustic calibrators and other accessories) 3. Measurement of sound pressure levels (exponential time weighting, linear averaging, maximum, equivalent, percentile sound pressure levels, frequency weightings (A-weighting and C-weighting), decibel scale) 4. Laboratory measurement of airborne sound insulation (requirements on acoustic laboratories and measurement equipment, laboratory measurement of sound reduction index of walls, floors, acoustical linings, windows, small technical elements, etc.) 5. Laboratory measurement of impact sound insulation (requirements on acoustic laboratories and measurement equipment, laboratory measurement of impact sound pressure level of floors, measurement of reduction of impact sound pressure level caused by floating floors and floor coverings) 6. Measurement of in situ sound insulation (requirements on measurement equipment, test procedure, evaluation of results) 7. Measurement of reverberation time (interrupted noise method) (requirements on measurement equipment, test procedure, evaluation of results) 8. Measurement of reverberation time (integrated impulse response method) and other quantities in room acoustics 9. Other measurement methods used in acoustics of buildings, measurement of loss factor, airflow resistance and sound absorption coefficient 10. Measurement of noise from stationary sources in buildings 11. Measurement of traffic noise 12. Uncertainties of measurement of acoustic quantities and their application in the evaluation of results 13. Regulations, requirements, summary
