ISVR3059 Acoustical Engineering Design

Module Overview

This module comprises two design exercises, the first examining practical isolation requirements and the second involved with designing an acoustic exhaust or intake with a required performance. The investigation will be conducted in groups, no larger than four students in total, on a particular system and the groups will be expected to consult widely relevant literature on the basic physical mechanisms of noise and vibration generation, transmission and quantification. Each team will present their findings and, in addition, their recommendations for further design improvement to be considered or implemented.

Aims and Objectives

Module Aims

To introduce design principles in acoustics and vibration and provide opportunity for the students to gain practical experience. The way in which this module covers this is to address applying the knowledge gained so far in some practical examples typical of those encountered by professional acoustic consultants.

Learning Outcomes

Disciplinary Specific Learning Outcomes

Having successfully completed this module you will be able to:

  • Take noise and vibration measurements, analyse the data for frequency content and interpret this in terms of the sources and transmission.
  • Develop appropriate physical models, produce a numerical implementation of such and then use the numerical models to design against specified targets.
  • Identify and quantify any vibration control features, e.g. isolation and compare against simple lumped parameter models where possible.
  • Produce a list of suggested design features and noise control improvements and predict what benefit these might produce.
  • Be able to present your findings to an engineering audience in a clear and well-structured oral and written presentation

Syllabus

Dependent upon the tasks required for the design problems. The module aims to cover a wide number of both acoustic and vibration principles and, where appropriate, include experimental validation/testing/quantification of the problem. It is anticipated that the following will be covered: • Noise and Vibration sources and their quantification • Vibration control methods • Noise Control Methods • Acoustic and vibration designs for practical implementation

Special Features

To some extent the investigations and objectives are open-ended and credit will be given for ‘thinking off the wall’, but supporting any ideas or suggestions with applicable engineering design and theory.

Learning and Teaching

Teaching and learning methods

The module will begin with a presentation of the aims and objectives, and then a brief overview of the tasks to be undertaken. Two projects will be run sequentially, and the groups will be different for each exercise. Background reading will be suggested and each group will be required to have weekly review meetings in addition to the experimental tests, which will be supervised where necessary.
