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.

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.
