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.
Preparations before course start

Support for students with disabilities
Students at KTH with a permanent disability can get support during studies from Funka:
LAB1 - Measurement Course, 0.5 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.
If the course is discontinued, students may request to be examined during the following two academic years.
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)
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.
