Acoustic Characterisation and Modelling of Multi-Fibrous Nonwovens (2024)
Thesis
Sharma, N. (2024). Acoustic Characterisation and Modelling of Multi-Fibrous Nonwovens. (Thesis). University of Salford

This thesis explores the theoretical, numerical, and experimental approaches for nonwoven materials with the intent of quantifying, testing, and characterising the acoustic performance of currently available products and to guide the development of a...

Nonlinear behaviour of lossy acoustic black holes (2024)
Journal Article
Umnova, O., Brooke, D., Leclaire, P., & Dupont, T. (in press). Nonlinear behaviour of lossy acoustic black holes. #Journal not on list, https://doi.org/10.61782/fa.2023.0652

Sound absorption properties of acoustic black holes are studied for high pressure amplitudes. The absorbers consist of thin circular plates, each with a central perforation, separated by annular air cavities. Radius of the perforation of each plate d...

FE Modelling Tibia Bone Vibration - The Influence of Shape, Twist, and Size (2024)
Journal Article
Scanlan, J., Umnova, O., & Li, F. (in press). FE Modelling Tibia Bone Vibration - The Influence of Shape, Twist, and Size. #Journal not on list, https://doi.org/10.61782/fa.2023.1141

The vibration response of bone has the potential to be used as a measure of bone strength for Osteoporosis detection. Modelling the vibration response requires capturing the shape of the long bones which have several complicated features. Yet modelli...

Urban Hedges as Noise Barriers: Does Plant Species Choice Affect Insertion Loss? (2024)
Journal Article
Webb, J., Cox, T., Blanusa, T., Griffiths, A., & Umnova, O. (in press). Urban Hedges as Noise Barriers: Does Plant Species Choice Affect Insertion Loss?. #Journal not on list, https://doi.org/10.61782/fa.2023.1152

Noise in urban environments is responsible for annoyance and adverse health effects. Noise barriers are used to mitigate noise and are effective when properly designed and installed, but provide little visual or biodiversity benefit. Hedges are frequ...
