Architecture and Building Acoustics
We spend about 90% of our time indoors, and consequently the acoustic quality of buildings is vital to well-being. Our research looks at all different building types: theatres, recording studios, schools, homes, open plan offices etc. Our research:
- Reduces noise indoors to improve quality of life.
- Improves speech intelligibility of announcements to improve accessibility.
- Researches and develops absorbing and diffusing treatments for rooms.
- Creates new approaches for measuring and predicting how sound moves within rooms and buildings.
- Develops understanding of how people respond to sound, to inform high-quality architectural design.
- Creates new measurement methods incorporated into international standards (e.g. BS ISO 17497-2:2012; ISO 140-18: 2006 and BS EN 15657-1:2009)
Current and future research focus includes:
- Modern Methods of Construction
- Building ‘Digital Twins’
- Metasurfaces and metamaterials for architecture
