Marshall Day Acoustics (MDA) is one of the world's leading acoustic consultancies. We provide specialist consulting in all areas of acoustics, with expertise in noise and vibration for a wide variety of projects including intricate performing arts spaces, large-scale civic and commercial developments, and expansive industry and transportation infrastructure.
Sir Harold Marshall and Christopher Day established Marshall Day Acoustics in Auckland, NZ in 1981. Peter Fearnside came on board as the third partner and founded Marshall Day Acoustics in Australia in 1987. MDA has been proudly 100% employee owned for more than 25 years, with over 30 employees in New Zealand and Australia invested in the company.
In our team, we have expert skills in traditional areas (environmental, building and room acoustics) as well as more specialised fields like vibration, marine and underwater acoustics, sound insulation theory and data acquisition.
We provide our advice in the most appropriate way for each project. This may include delivering reports, design advice, peer reviews, expert evidence, seminars, community and stakeholder consultation, developing policies and guideline or virtual reality simulations.
In addition to our specialist acoustic consulting work, we develop high quality acoustic design tools (INSUL, IRIS, dBWav, dBSea, Zorba) that are used globally by scholars, consultants, designers, and manufacturers. We are continually looking to improve our services, expand our technical expertise and develop our equipment and systems in order to provide the most comprehensive and cutting-edge design tools.
