1. Descision

This course is established by School of Engineering, Department of Electrical Engineering 2013-12-18. The course syllabus is approved by Department of Engineering 2013-12-18 and applies from 2013-12-18.

2. Entry requirements

For admission to the course the following course is required:
- Signal Processing I, ET1203, 7,5 credit points or the equivalent.

3. Objective and content

3.1 Objective

The course aims at giving the students basic knowledge of sound- and vibration measurements. The course also reflects how modern signal analysis is applied for the measuring of sound and vibrations. The student will be well prepared for sound- and vibration measuring within the industry as well as for continued studies in the subject.

3.2 Content

· Mechanical systems

· Transducers for noise and vibration analysis

· Frequency analysis

· Experimental frequency analysis

· Spectrum estimation using the FFT

4. Learning outcomes

The following learning outcomes are examined in the course:

On completion of the course the student will:

  • be able to understand and use the basic theory for dynamic systems in mechanics.
  • have acquired a basic understanding of modal analysis.
  • be able to understand and analyze measurement-technical problems in sound- and vibration measuring.
  • have knowledge of different measuring methods and sensors that are used for the measuring of sound and vibrations.
  • be able to measure and interpret sound- and vibration spectra.
  • be able to measure frequency responses and coherence functions.
  • be able to use a frequency analyzer.
  • have acquired a basic understanding of revolution-per-minute (RPM) analysis in order to understand and solve vibration- and noise problems in relation to rotating. machines

5. Learning activities

During the lectures the teacher introduces the theoretical foundations and connects the theory to practical applications in the industry. In the project work the student is able to practise the theoretically acquired knowledge and learn how to handle data acquisition systems and advanced measuring instruments for sound- and vibration measurements. The project work is compulsory and will be carried out individually or in a group. The project work includes the presentation of the work in the form of a report. In order for the student to practise theory, theoretical assignments are handed in. The assignments that are handed in are compulsory and must be done individually.

6. Assessment and grading

Modes of examinations of the course

Code Module Credit Grade
1405 Written exam 3.5 credits AF
1415 Project 3 credits GU
1425 Assignment 1 credits GU

The course will be graded A Excellent, B Very good, C Good, D Satisfactory, E Sufficient, FX Failed result, a little more work required, F Fail.

1 Determines the final grade for the course which will not be issued until all items have been passed.
The examination will take place through a written examination and of the handing in of the compulsory assignments and of the project work assignments. Grading of the project work assignments will be done through the grades Godkänd [Passed] or Underkänd [Failed]. For a final grade of the course the grade Godkänd [Passed] is required for the project work part and also for the assignments that are to be handed in.
Upon request grades may also be given in accordance with the ECTS.

The information before a course occasion states the assessment criteria and make explicit in which modes of examination that the learning outcomes are assessed.

An examiner can, after consulting the Disability Advisor at BTH, decide on a customized examination form for a student with a long-term disability to be provided with an examination equivalent to one given to a student who is not disabled.

7. Course evaluation

The course evaluation should be carried out in line with BTH:s course evaluation template and process.

8. Restrictions regarding degree

The course can form part of a degree but not together with another course the content of which completely or partly corresponds with the contents of this course.
