Course specific prerequisites

VTA081 - Technical acoustics 1

Aim

The course is an advancement and continuation of Technical Acoustics 1. The course gives the students the opportunity to apply the theoretical frame that was given in Technical Acoustics 1 to real life problems.

Learning outcomes (after completion of the course the student should be able to)

  • Identify and formulate a complex problem in structural acoustics based on measured and calculated data and achieve solutions for such a complex problem taken from real life
  • Define performance requirements as goal function for noise control measures
  • Select and apply the fundamental concepts methods and tools to solve the problem (e.g. wave approach, modal approach, description of damping, SEA, BEM, etc.) to model the behaviour of a complex structure with respect to vibration and radiation
  • critically evaluate the functioning of models tools and methods in different context by comparing these results with experimental results
  • draw conclusions from model results and use this conclusions to derive for a generalised view on how to apply noise control engineering measures
  • suggest innovative noise control measures based on own studies and research
  • design and evaluate the suggested solution with respect to given constraints such as goal functions for the expected noise and vibration properties
  • carry out the different steps of the work inside a team with distributed tasks
  • communicate results colleagues and teachers in appropriate form

Content

The course focuses on analytical and numerical methods for describing vibrations and structure fluid interaction. It includes the application of
  • Wave approach
  • Finite Element Methods (FEM)
  • Statistical Energy Analysis (SEA)
  • Boundary Element Methods (BEM)
to a real life structure.
The application and functioning of the methods is validated by measurements results which are provided by the teachers. In a final work noise reduction measures have to be designed where also vibration isolation and its application is included. The suggested measures are implemented and experimentally validated.

Organisation

The course is divided in three parts
Part 1: Vibrations properties of the test structure
Part 2: Radiation from the test structure
Part 3: Redesign solutions for the test structure
Each part results  in a written reports summarising all reports. Each part introduces with a series of lectures.

Literature

Material produced by the department as well as recommended literature which is provided at www.ta.chalmers.se

Examination including compulsory elements

Oral presentation of the final results combined with three written reports. The mark is based on the marks for the presentation (20%) and the marks for the three reports (80%). The students have to pass all parts.

The course examiner may assess individual students in other ways than what is stated above if there are special reasons for doing so, for example if a student has a decision from Chalmers on educational support due to disability.
