Presentation / Conference
Casagrande Hirono, F., Torija Martinez, A., Elliott, A., Taylor, J., Grimshaw, S., & Lefas, D. (2022, June). Aeroacoustic design and optimisation of an all-electric ducted fan propulsion module for low-noise impact. Presented at 28th AIAA/CEAS Aeroacoustics 2022 Conference, Southampton, UK

This paper discusses the aeroacoustic aspects of the design, construction and testing of an all-electric ducted fan propulsion module for future electric aircraft. An overview of the propulsor aerodynamic design is provided. Acoustic measurements mad...

Vibro-electric transfer path analysis of a solid body electric guitar (2018)
Presentation / Conference
Elliott, A., Magill, J., & Kendrick, P. (2018, April). Vibro-electric transfer path analysis of a solid body electric guitar. Presented at Acoustics 2018, Cardiff, Wales

Solid bodied electric guitars typically employ one or more magnetic pickups attached to the guitar body in close proximity to the guitar strings. At low frequencies the amplitude of the vibrating string is typically far greater than vibrations transm... Read More about Vibro-electric transfer path analysis of a solid body electric guitar.

Blocked forces for the characterisation of structure borne noise (2015)
Presentation / Conference
Elliott, A., Meggitt, J., & Moorhouse, A. (2015, August). Blocked forces for the characterisation of structure borne noise. Presented at Internoise 2015, San Francisco

During the development of complex assemblies such as aircraft the noise from installed components must be considered. For airborne sound sources this issue has been resolved to some extent by standard measurement procedures which allow equipment supp...

Detailed directivity measurements of aerodynamic sound sources (2015)
Presentation / Conference
Elliott, A., Meggitt, J., & Moorhouse, A. (2015, April). Detailed directivity measurements of aerodynamic sound sources. Presented at Noise and Vibration - Emerging Technologies, Dubrovnik, Croatia

The sound radiated by a vibrating surface can be modelled using combinations of elementary sources but for aerodynamic noise sources it less clear how to do so. It is proposed here that the arrangement and number of ideal sources required to represen... Read More about Detailed directivity measurements of aerodynamic sound sources.

In-situ characterisation of structure borne noise from a building mounted wind turbine (2010)
Presentation / Conference
building mounted wind turbine. Presented at ISMA 2010, Katholieke Universiteit Leuven, Belgium

Building mounted micro wind turbines (BMWTs) could potentially provide a useful contribution to renewable energy production but a means of predicting structure-borne sound and vibration is required. A particular difficulty is that BMWTs can only be... Read More about In-situ characterisation of structure borne noise from a building mounted wind turbine.

On the use of experimental ensembles in a hybrid deterministic-statistical energy analysis method
Presentation / Conference
Clot-Razquin, A., Langley, R., Meggitt, J., Moorhouse, A., & Elliott, A. On the use of experimental ensembles in a hybrid deterministic-statistical energy analysis method. Presented at International Conference on Noise and Vibration Engineering (ISMA) / International Conference on Uncertainty in Structural Dynamics (USD) 2020, Leuven, Belgium

There is a clear need in modern industries for models that can predict the vibro-acoustic response of their manufactured products at the design stage. Models based on the hybrid deterministic-statistical method are a suitable solution to overcome the...

Component replacement transfer path analysis
Presentation / Conference
Meggitt, J., Elliott, A., Moorhouse, A., Jalibert, A., & Franks, G. Component replacement transfer path analysis. Presented at International Conference on Noise and Vibration Engineering (ISMA) / International Conference on Uncertainty in Structural Dynamics (USD) 2020, Leuven, Belgium

In-situ Transfer Path Analysis (TPA) is a diagnostic method used to analyse the propagation of noise and vibration through complex built-up structures. Its defining feature is the independent characterisation of an assembly's vibratory source in term... Read More about Component replacement transfer path analysis.

Passive acoustic thermometry
Presentation / Conference
Elliott, A. Passive acoustic thermometry. Presented at Internoise 2016, Hamburg

Conventional acoustic thermometry is usually performed by exciting a resonator with a sound source and identifying the resonant frequencies of the system. If the dimensions of such system are known it is relatively straightforward then to determine t... Read More about Passive acoustic thermometry.
