Profile
I began my PhD at the University of Salford assisting Andy Moorhouse with a project to enable Virtual Acoustic Prototypes (VAP) to be made for lawnmowers. Virtual Acoustic Prototypes allow a machine to be built, tested and optimised computationally by breaking them down into noise components that can be altered individually. Many measurements were required to characterise each noise source and associated transmission paths.
This period gave me an excellent introduction into many types of acoustic measurement. After approximately 12 months I was given the opportunity to study at INSA-LVA, Lyon, France (Laboratoire Vibrations Acoustique) with the EDSVS scheme (European Doctorate in Sound and Vibration Studies). Whilst in Lyon I continued with the same work but the emphasis shifted more towards structure-borne sound.
About the Project
At the current time I am investigating methods for obtaining the data required for structure-borne power prediction. The methods I am investigating are commonly called in-situ methods as all measurements are made while the source (e.g. machine) and receiver (e.g. base) are connected. Conventionally source and receiver would be characterised independently whilst separate. The advantage with in-situ measurement is that the source is characterised under the same conditions and restraints as for the situation in which it is likely to be used. It is hoped therefore that in-situ methods will give more reliable results in addition to making measurements easier.
About me
Since my early teenage years my main interests have been loud heavy music and cars… In order to further my understanding in these areas in 1998 I came to the University of Salford joining the physics department to study Physics with Acoustics. After graduating I became interested in combustion as many young men do. I decided to study Combustion and Energy at the University of Leeds to satisfy my curiosity and further my understanding of engines. I carried out a research project into the burning velocity of fuel sprays. This involved injecting fuel into a combustion vessel or bomb, igniting the mixture and filming the resulting ball of fire using a high speed camera. During all this time I worked part time as a mechanic so after graduating from Leeds I began to work full time. This was until I was given the opportunity to study engine noise and vibration at Salford… which brings us right up to date.
