Location: The course will be run at the University of Salford’s Acoustic Research Centre. Acoustics and audio research has been conducted at Salford University for over 60 years. It is funded by research councils, national and international government bodies, and industry. Our research has fed into products that companies make and sell worldwide, as well as regulations and standards used in the UK, Europe and internationally.

PROGRAMME

To coincide with Internoise 2022 (Glasgow), the University of Salford’s Acoustics Research Centre will be running a 3-day short course on Virtual Acoustic Prototyping: Methods for predicting noise and vibration in complex structures.

Virtual acoustic prototypes are computer representations of products (ranging from domestic appliances to vehicles, trains, planes, and even buildings) that can be used predict their sound and vibration response before they are even built! This is done by characterising the individual components that make up the product, and combining them mathematically to build a virtual product assembly, thus enabling perceptually motivated acoustic design.

The course will:

Introduce the concepts of virtual acoustic prototyping and perceptually motivated acoustic design.

Cover the theoretical background required to build VAPs (including component characterisation, blocked force (ISO 20270:2019) and sub-structuring methods).

Develop your experimental and computational skills to implement component characterisation methods, perform analysis, and build VAPs.

The course will involve a mixture of lecture and practical laboratory work (50/50 split). Lectures will introduce theoretical background and technical concepts. Practical sessions will cover everything from setting up and conducting experiments, to coding and implementing theory and analysing results. By the end of the course, you will have built your own Virtual Acoustic Prototype.

Day 1 - Introduction to virtual acoustic prototyping and component characterisation - In the lectures we will introduce the necessary background theory (mobility and impedance concepts) and discuss the passive and active (blocked force - ISO 20270:2019) characterisation of components. In the practical session we will instrument a simple test rig, perform impact FRF measurements, and export and analyse data in MATLAB/Octave.

Day 2 - Blocked forces and resilient elements - In the lectures we will discuss some practical considerations regarding blocked force characterisation and introduce methods for characterising resilient elements such as vibration isolators. In the practical session we will perform a blocked force characterisation on a representative laboratory structure.

Day 3 - Dynamic sub-structuring and virtual acoustic prototyping - In the lectures we will introduce the basics of dynamic sub-structuring (building a virtual assembly from component-level data) for virtual prototyping and discus some applications of virtual acoustic prototyping. In the practical sessions we will build a VAP using data collected over days 1-2.
