Higher-fidelity analysis of air source heat pump noise via scanning intensity measurement (2024)
Presentation / Conference Contribution

The need to shift to reduce carbon emissions to hit Net Zero is currently driving plans for large scale rollouts of Air Source Heat Pumps (ASHPs), due to their increased thermal efficiency and lack of direct carbon emissions. Concern exists, however,... Read More about Higher-fidelity analysis of air source heat pump noise via scanning intensity measurement.

A dynamic stiffness method to estimate the sound insulation of an arbitrarily installed thick cross laminated timber (CLT) plate (2024)
Presentation / Conference Contribution

There is no generally accepted standard methodology to determine the dynamic constants of whole cross laminated timber (CLT) plates. Combined with the observation that CLT walls or floors are installed in situ under very different conditions to labor...

Urban Hedges as Noise Barriers: Does Plant Species Choice Affect Insertion Loss? (2024)
Presentation / Conference Contribution

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...
