Celebrating 50 years of the iconic Perth Concert Hall
This month marked the 50th anniversary of the iconic Perth Concert Hall (PCH) with acoustic design by Sir Harold Marshall – co-founder of Marshall Day Acoustics. This much-loved heritage building opened on 26 January 1973 and half a century later is widely considered to have some of the finest acoustics in the Southern Hemisphere.

A Virtual Success: 2021 Marshall Day Acoustics Conference
Every two years MDA gets together with staff from offices across Australia, New Zealand, China, Hong Kong and France for a company-wide conference. This year was a bit of a challenge to bring everyone together in one place, so we did things a little differently by holding our very first virtual conference on Friday, 26 November 2021.

Clear and intelligible speech communication is essential to the learning process.
Acoustic conditions in classrooms must support a wide variety of teaching methods. Speech clarity, noise intrusion and sound transfer are key areas of concern while specialist uses such as music and technology provide additional challenges.Read More

Our Sightlines program has the potential to revolutionise the way venue sightlines are analysed
Subjectivity has long been a drawback of traditional sightline analysis methods, despite the advent of 3D visualisation techniques. Our Sightlines modelling tool enables design teams to quickly and objectively visualise how sightlines are obscured by physical barriers such as handrails, balustrades and other patrons. Importantly, for the first time, this analysis is available for each individual seat and as a percentage matrix of the venue's overall 'visual health'.
The Sightline system is ideally suited to:
- Concert halls & theatres
- Sports venues and stadiums
- Convention centres and cinemas
We provide acoustic engineering services spread across the North & South Island with offices in Auckland, Christchurch, Hamilton, New Plymouth & Wellington.
Our team shares one common focus - to provide innovative acoustic solutions of the highest standard.
We provide expertise across every sector. Here we are proud to share some of our most interesting projects.
