Intended learning outcomes
The overall aim is to promote the development of quiet and vibration-free products and processes. The course participants should be provided knowledge necessary to carry out a relevant analysis of the sound and vibration properties of a product. The knowledge should also serve a basis for possible further studies in the sound and the vibration field.
After completing the course the student should be able to
- Account for and explain key sound and vibration concepts and quantities.
- Account for environmental consequences of sound and vibration.
- Account for, explain and critically choose relevant mathematical models and methods to describe important sound and vibration quantities.
- Apply relevant mathematical models and methods to calculate important sound and vibration quantities.
- Measure a products sound emission properties.
- Measure and assess the hand-arm vibration exposure of a handheld tool.
Literature and preparations
Completed courses in mathematics (minimum 7.5hp) that gives knowledge of analytical and numerical methods för solving differential equations. Course contents similar to that of SF1523 and completed course in mechanics (minimum 6hp) that gives knowledge in particle dynamics similar to that of SG1102.
Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
- LAB1 - Laboratory Exercises, 1.0 credits, grading scale: P, F
- TENA - Written Theory Examination, 3.0 credits, grading scale: P, F
- TENB - Written Problem-solving Examination, 2.0 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.
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination
- 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.
