Prerequisite/Recommended prerequisite for participation in the module

The module adds to the knowledge obtained in Fundamentals of Acoustics and Electro-acoustics (1st semester)

Content, progress and pedagogy of the module

Learning objectives

Knowledge

  • Room acoustics
    • Sound fields in rooms
    • Absorption and reflection (e.g. impedance, absorption coefficient, porous and resonating absorbers)
    • Room modes (e.g. standing waves, distribution and classification of modes)
    • Geometrical and statistical acoustics (e.g. ray tracing, mirror image modelling, sound field build-up and decay, reverberation time: Sabine+Eyring)
    • Concert hall acoustics (Room acoustical parameters like e.g.: T60,T30,T20, EDT, C80,C50, D, IACC, Subjective parameters, conditioning of rooms, Echo)
    • Speech intelligibility (e.g. STI and RASTI index)
  • Building acoustics
    • Sound transmission between rooms
    • Sound transmission into buildings (facade insulation)
    • Air borne sound transmission (e.g. Single wall Double walls, measurement of transmissions loss)
    • Structural borne sound transmission (e.g. waves in solids, attenuation, impact noise, measurement of impact sound insulation)
  • Environmental Acoustics
    • Effect of noise on humans (annoyance and damage) (Physiological reactions, sleep disturbance, work performance, assessment via questionnaires)
    • Noise Classification (types of noise, influence of surroundings, SPL, Frequency and time average, equivalent and exposure levels)
    • Noise from installations
    • Noise barriers
    • Noise assessment (ratings and noise descriptors, calculation of loudness, assessment of annoyance and hearing impairment)
  • Relevant standards and legislation

Skills

  • calculate and measure relevant room and building acoustical parameters
  • measure and calculate relevant noise assessment parameters
  • carry out measurements and calculations on noise barriers

Competences

  • Sound fields in rooms
  • Sound transmission into rooms
  • Noise impact on humans based on relevant theories, standards, measurement and prediction methods.
