In modern urban life, people spend a considerable amount of time in the urban outdoor environment for work, commuting, recreation or sports. Exposure to urban noise can have negative psychological and physiological effects on people's health. With the increasing density of buildings and road traffic noise in cities, urban acoustics have become a pressing social issue.

In recent years, attention has shifted from indoor to outdoor acoustics. Acoustic design in cities is undergoing a process of transformation from noise reduction, based initially on numerical levels, to multi-sensory design that values perceptual attributes. The acoustic group focuses on reducing urban noise pollution through the production of hollow ceramic components tuned to local noise frequencies. The research question that has been investigated explores alternative strategies for the design and manufacture of clay Helmholtz resonators to alter the soundscape of external spaces.
