ESR project "Modelling of structure -borne sound transmission in lightweight buildings"
Acoutect is a European project running from January 2017 until December 2020. The project has received funding from the European Union's Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement number 721536.
Acoutect marries “Acoustics” and “Architect” and responds to the important role that Acousticians have in the design of modern buildings. The overarching aim of Acoutect is to set up a PhD training network on building acoustics and react to the acoustic challenges stemming from modern building concepts to deliver sustainable indoor environments with respect to health and well-being.
Within this project we are seeking an Early Stage Researcher (ESR) for a duration of 36 months to carry out a PhD with the Acoustics Research Unit (ARU) in the School of Architecture at the University of Liverpool in the UK.
The ARU specialises in research, supervision of postgraduate research study (PhD and MPhil), training, knowledge exchange and consultancy.
Our research focuses on airborne sound and structure-borne sound in the fields of engineering acoustics, building acoustics, room acoustics, audio acoustics, psychoacoustics, human vibration, environmental noise and industrial acoustics. Particular emphasis is placed on the development of prediction models with validation using laboratory experiments, and experimental studies on subjective evaluation.
In the last UK research assessment exercise, the Research Excellence Framework (REF 2014), the school was the highest ranked department submitted solely as a School of Architecture with a top six place for research intensity, a top ten place for grade point average and a top three place for research outputs, with 80% of our publications rated as world leading or internationally excellent.
Physically, the ARU offices and laboratories are situated in the Department of Engineering. These laboratories include an anechoic chamber, a semi-anechoic chamber, two reverberant chambers and an audiometric booth. State-of-the-art instrumentation is available for sound and vibration measurement.

The research for the PhD will focus on the development of prediction models that can inform engineering design on noise and vibration transmission in lightweight buildings, particularly from machinery and impacts from people. There are several critical or unresolved aspects that need to be addressed: (a) modelling of vibration transmission across lightweight framed walls and floors which cannot be treated as precise periodic structures, (b) predicting maximum Fast time-weighted sound pressure levels in rooms due to building machinery and heavy impacts from people on lightweight floors (c) prediction of low-frequency airborne and impact sound insulation.
The modelling will be based around approaches such as Finite Element Methods (FEM), and steady-state and transient forms of Statistical Energy Analysis (SEA). The aim is to provide validated approaches to prediction that can be based around numerical models in combination with laboratory measurements.
The research will equip the ESR with skills and experience relevant to acoustic engineering jobs in the construction sector or academia, with skills that are potentially transferable to research in the automotive, marine and aeronautic sectors.
