Content and learning outcomes

Course contents

  • Theory for elastic waves in fluids and solids
  • Human response to sound and vibration
  • Fourier methods, linear systems and frequency response functions
  • Vibration isolation
  • Vibrations in beams and plates
  • Spherical and cylindrical sound waves
  • Energy methods and room acoustics
  • Flow Acoustics
  • Sound in ducts and mufflers
  • Measurement methods

Two measurement exercises are included in the course.

Intended learning outcomes

The course aims at presenting the fundamental ideas and theories necessary to understand and analyse elastic wave phenomena in fluid or solid media. The course also gives an introduction to signal analysis and measurement techniques as well as human reponse to sound and vibration. The goal is to give the student a good understanding of the theory and illustrate important applications ranging from design of consert halls to quite vehicles and low noise fans.

After the course students should be able to:

  • Describe fundamental concepts of engineering noise and vibration, measurement techniques and instruments. Explain the effect of noise and vibrations on humans and equipment.
  • Apply Fourier analysis to solve coupled differential equations, calculate the frequency content of periodic and transient signals and implement this knowledge to analyse mechanical systems. Describe methods to distinguish between linear and non-linear mechanical systems.
  • Understand the physical foundations and the mathematical models of sound waves in fluids and solids, wave propagation, transmission, reflection and radiation and understand how to apply these models to sound and vibration problems in mechanical and vehicle engineering.

Examination and completion

If the course is discontinued, students may request to be examined during the following two academic years.

Grading scale

A, B, C, D, E, FX, F


  • LAB1 - Measurement Course, 0.5 credits, grading scale: P, F
  • TEN1 - Exam 1, 3.0 credits, grading scale: P, F
  • TEN2 - Exam 2, 2.5 credits, grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Other requirements for final grade

Written theory examination (TEN1, 3 university credits), Written poblem solving examination (TEN2, 2.5 university credits). Approved measurement exercises (LAB1, 0.5 university credits)

Opportunity to complete the requirements via supplementary examination

No information inserted

Opportunity to raise an approved grade via renewed examination

Ethical approach

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
