ACOUSTICS - AN OVERVIEW

  • Acoustics – what is this? How is sound radiated by source?
  • Basic quantities of sound in the 3D field
  • The wave equation – typical solutions in 1D and 3D
  • The energy in waves – intensity and sound power
  • Spectrum analysis of sound signals
    • Narrow band and octave band analysis
  • The loudness of sound
    • Definition and usage of the decibel scale
  • The human perception of sound
  • Room acoustics
    • What is reverberation time?
    • Sound attenuation of walls
  • Noise identification with machine learning
