Our Company

Day Design Pty Ltd was founded by Athol Day in 1982. Since that time we have provided “Good Acoustics by Design” to clients all over Sydney and beyond. Our reputation speaks for itself, with the majority of our work coming from repeat clients or from people who were recommended to us.

Day Design staff have amassed a wealth of theoretical and practical knowledge over several decades of practice in the field of Acoustics. All of our acoustical engineers are professionally qualified and some have taken out post-graduate Masters Degrees in acoustics.

After working with Day Design for 5 years, Stephen Gauld took over as Managing Director in February 2004, ensuring that the foundation built by Athol Day continues to be built upon.

The design of acoustical enclosures and silencers for various machines requires an understanding of general engineering and building construction. Our engineers are trained to design acoustic structures that are both practical and cost-effective with due consideration being given to maintenance access and the efficient functioning of machines and buildings.
