2. Sound measurement, frequency band, frequency band analysis, noise report, hygienic limits.
3. Urban acoustics, noise attenuation.
4. Room acoustics, diffuse sound field, sound field.
5. Absorptive constructions, membranes and oscillating plates, Helmholtz resonators.
6. Sound insulation, rating of air-born and structure-born sound insulation.
7. Air-born sound insulation, Watter’s method.
8. Impact sound insulation of building constructions.
Daylighting and insolation of buildings:
9. Solar radiation, insolation, requirements for insolation.
10. Light and photometry. Methods of evaluation of daylighting in buildings, Daniljuk’s nomograms.
