Shaun King recently visited the Central Interceptor May Road site, where he went down a 75m shaft and ventured a short distance into the 4.5m tunnel. The Central Interceptor is the largest wastewater project in New Zealand.

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

We are thrilled to share that Marshall Day Acoustics has been named winner of the 2022 Hugh Vivian Taylor Award for our work encompassing the management of low frequency port noise.

Specially designed reactive ship silencers have been installed on 6 Rio Class Maersk ships to reduce unwanted noise at Port Otago. The new devices have been attached to the auxiliary engines to reduce the low 'rumble' when in port and help to improve the quality of life in the local community.
