24 n/a 76 100 MODULE AIM (i) To enable students to appreciate and to analyse the generation, propagation and control of sound waves in an engineering context. (ii) To enable students to quantify and analyse the effect of sound waves and vibrations on mechanical systems, humans and the environment. (iii) To gain an awareness of the framework of relevant legal requirements governing acoustic emissions. MODULE LEARNING OUTCOMES By engaging successfully with this module a student will be able to

(i) Use knowledge of relevant mathematics to analyse and calculate the acoustic emissions from the vibration of simple systems.

(ii) Demonstrate an understanding of the physiology and psychology of human hearing and an awareness of the subjective nature of sound.

(iii) Understand the engineering principles of acoustic enclosures, barriers and transmission paths and apply these concepts to minimise noise and vibration in typical engineering systems.

(iv) Understand the legal requirements on management and the workforce in relation to noise in the workplace and to develop an appreciation of the health and safety issues of typical vibroacoustic hazards / effects such as vibration white finger, noise induced hearing loss and motion sickness etc.

INDICATIVE CONTENT

Review of waves and simple vibration concepts, fundamentals of acoustics, definitions and units, simple formulae and calculation involving sound pressure, sound power, sound intensity and logarithmic units.

The human ear, psychoacoustics, subjective noise, sound quality, jury evaluation..

Module 55-604243

Absorption and insulation, machine noise, noise transfer functions, damping, acoustic generation and propagation, room acoustics, acoustic modes and resonances.

Hearing hazards, vibration white finger, noise induced hearing loss, effects of vibration on human response, legal issues, standards and regulations, environmental noise.

Acoustic measurement and instrumentation.

Structural failure due to vibro-acoustic effects.

Design for noise and vibration control.

Case studies from automotive, aerospace and general product design fields. LEARNING, TEACHING AND ASSESSMENT - STRATEGY AND METHODS Students will be supported in their learning, to achieve the above outcomes, in the following ways:

Learning & Teaching The material will be presented via active-learning and problem-based seminars with examples and case studies to illustrate the principles involved. This will be reinforced in laboratory classes where the students will carry out experiments to gain appreciation of the relevant concepts. Tutorial classes will also be used where necessary to give the students an opportunity to analyse problems and to receive guidance in applying established rules and standards.
