Course content

This is an introductory course in acoustics. The focus is on fluids (both gases and liquids). The whole spectrum of acoustics is considered, from infrasound to ultrasound.

  • Oscillators and lumped systems
  • Strings and bars (longitudinal waves only)
  • Wave equations and their solutions
  • Sound generation, radiation and reception
  • Reflection and transmission
  • Pipes and resonators
  • Cavities and waveguides
  • High frequency approximations, geometrical acoustics and the diffuse field
  • Attenuation within the medium and refraction
  • Introduction to diffraction and scattering
  • Introduction to moving sources and moving fluids
  • Introduction to non-linear acoustics

Learning outcome

Knowledge:

The candidate has

  1. In-depth theoretical basis for generation, propagation, reception and damping of acoustic waves in fluids (both gases and liquids) for basic geometries and systems,
  2. Introductory knowledge of diffractionn, aeroacoustics and non-linear acoustics.

Skills:

The candidate

  1. can analyze the behaviour of acoustical systems amenable to analytical approaches
  2. knows how to record calibrated acoustic signals
  3. has a first experience of numerical simulation of acoustic wave phenomena

General competence: The course gives experience in the analysis and modeling of physical systems with analytical approaches, in the use of measurement equipment, in programming numerical methods, ard in report writing.

Learning methods and activities

  • Lectures
  • Experiments
  • Field measurements
  • Theoretical exercises
  • Laboratory measurements
  • Simulations

Compulsory assignments

  • Theoretical tasks

Further on evaluation

The student has to deliver at least 4 of the 6 written assignments during the semester. Each assignment consists of theoretical tasks in line with the content of the lectures. The assignments help the student train for the exam.

Report nr 1 is based on field measurements performed by the students in small groups. The measurements need to be analyzed and discussed. The individual report is delivered with calibrate sound recordings.

Report nr 2 is based on the implementation and use of a simple numerical method and its use to simulate different acoustic phenomena.

If the course is to be repeated, all parts of the course must be taken. Compulsory activities from previous semester may be approved by the department.

Required previous knowledge

Knowledge in mathematics (TMA4101, TMA4106, TMA4111, TMA4116) and physics (TFY4115 ) corresponding to 1st and 2nd year of the study program for electronics:

Necessary basic acoustic theory will be given during the course.
