Research tackles noise and ventilation challenges in Aotearoa’s cities

As cities in Aotearoa New Zealand grow denser, noise pollution and poor ventilation are becoming major concerns for residents.

Traditional building materials often fail to address both issues, forcing occupants to choose between peace and quiet or airflow.

Dr Andrew Hall from the Faculty of Engineering and Design at the University of Auckland is leading cutting-edge research to develop advanced materials that could transform building design and address this challenge.

The research is supported by a Mana Tūānuku Research Leader Fellowship, with the project receiving $1.16 million in funding over the next four years.

His work focuses on developing specially designed materials that can block noise while allowing airflow, helping to improve sound insulation and ventilation in homes, particularly in windows, walls and doors.

By exploring how sound waves interact with these materials and how different materials work together, Hall aims to create a new class of high-performance building solutions that enhance comfort, energy efficiency and overall well-being. 

“Part of this research is around windows and designing a transparent acoustic screen that creates a noise barrier but allows airflow and light in. You’ll be able to partially open a window, and the system will reflect, absorb and redirect the sound from coming in.”

This investment could pave the way for quieter, healthier and more affordable homes, reshaping the future of urban living in Aotearoa New Zealand, says Hall.

“Understanding how these different materials interact together is key to optimising their performance. This work has the potential to provide a step change in the construction industry, with lightweight, high performing systems all using less raw material, making them more affordable in the long run.”
