  • define fundamental acoustical issues
  • describe how to measure and analyze sound
  • explain fundamental principles of sound transmission, sound absorption and sound proofing
  • calculate sound insulation in block of flats
  • describe the propagation of a fire from ignition to a fully developed fire
  • calculate some effects of burning liquids and solids
  • define fire load density and opening factor
  • describe the most important material properties in fire for commonly used building materials
  • calculate temperatures in fully-developed compartment fires
  • calculate the fire resistance for building components
  • design simple buildings for safe evacuation in case of fire
