2018/2019

Content, progress and pedagogy of the module

Learning objectives

Knowledge

  • Must have knowledge about the basic acoustic quantities, their physical significance, and their role in the description of an acoustic process.
  • Must be able to understand the relationship between the acoustic variables and the theoretical basis for the development of the wave equation.
  • Must have knowledge about the principles of sound emission and reception.
  • Must have knowledge of the construction, mechanisms and use of different types of acoustic transducers.
  • Must be able to understand how acoustical transducers work in three domains: The electrical, the mechanical and the acoustical, and thus be able to transform between the three domains.
  • Must have knowledge of the different measurement procedures and techniques used in acoustics.
  • Must have knowledge of signal processing techniques in acoustic measurement to obtain time and frequency characteristics of acoustic signals.
  • Must have knowledge about acoustical filters and their use.

Skills

  • Must be able to identify relevant acoustic variables for a given sound source and sound field.
  • Must be able to apply the proper assumptions in the calculation or estimation of relevant acoustic variables
  • Must be able to select the proper analytical description for the behavior of sound waves in rooms and cavities.
  • Must be able to model and measure acoustical transducers.
  • Must be able to measure the electro-acoustic parameters of loudspeakers.
  • Must be able to calibrate and use electro-acoustic transducers to obtain reproducible measurement.
  • Must be able to select and use exiting transducers based on their parameters.
  • Must be able to choose and calibrate the adequate equipment for a given measurement and to be able to identify and eliminate sources of error.

Competences

  • Must be able to apply theoretical acoustic principles to model the behavior of acoustic systems, such as pipes, resonators, musical instruments, rooms and other enclosures, ventilation ducts, smartphones etc.
  • Must be able to design, carry out and document repeatable acoustic measurements.

Type of instruction
