Marshall Day Acoustics was co-founded in 1981 by Christopher Day and Sir Harold Marshall in Auckland, New Zealand. In 1987, Peter Fearnside became the third partner and founded Marshall Day Acoustics in Australia, whilst also developing the business significantly into the S.E Asia and China markets. Many of the technical innovations and industry-leading acoustic design tools for which Marshall Day Acoustics has become widely respected have been led by Keith Ballagh, who became a partner in 1990.
Our growth over the past 40 years now sees more than 90 professional staff employed throughout New Zealand, Australia, China, Hong Kong and France with over 20 employee shareholders invested in the company.
From our beginnings as a local consultancy, we have carefully evolved into one of the largest acoustic engineering firms worldwide, working on major projects in over 15 countries.
Sir Harold Marshall KNZM
Sir Harold Marshall is an architect, engineer and physicist who is recognised internationally for his contribution to concert hall design. Formerly Professor of Architecture at the University of Auckland and Head of the Acoustics Research Centre, Dr Marshall has over 45 years experience in the acoustical design of auditoria and concert halls. His work is widely cited in technical literature and his interest in these fields has been sharpened by his active involvement in musical performance both as a chorister and as a bass-baritone.
“I regard the acoustic designs of Marshall Day Acoustics to be amongst the finest and probably the most innovative in the world”
