Associate Professor Benjamin Cazzolato
Ben Cazzolato began research in the field of acoustics and vibrations
as an undergraduate at the University of Adelaide in the School of Mechanical Engineering & graduated with 1st Class Honours in a Bachelor of Engineering degree (Mechanical Engineering) at the University of Adelaide in 1990.
After completion of undergraduated studies, he commenced employment with VIPAC Engineers & Scientists as a consulting engineer
where he worked on a varied number of projects:
- Industrial Noise Surveys, including assessment of risk to hearing damage,recommendations for noise control, ranking of sources and generation of noise contour maps (S.A. Brewing Co.).
- Ground Vibration Monitoring and damage assessment (PRA - Mobil, Koukourou & Partners, Coffee & Partners).
- Sound absorption and Transmission loss measurements of materials (Lysaght Industries).
- Modelling and design of acoustic panels to increase transmission loss (James Hardie).
- Significant experience in underwater-acoustics including towed array performance testing, involving data acquisition, instrumentation support, signal processing of hydrophone and accelerometer signals, data analysis, interpretation and reporting (Commonwealth Procurement Office, Defence Science & Technology Organisation, GEC Marconi Systems).
- System modelling of land based flow noise testing facilities for the purpose of understanding array performance (Commonwealth Procurement Office, Defence Science & Technology Organisation, GEC Marconi Systems).
- Vibration Condition Monitoring of rotating equipment (Bridgestone Tyre Division, APCEL, Dept. of Marine & Harbours, Adelaide Brighton Cement, Detroit Engine & Turbine Co.).
- MFP Environmental Impact Statement support (PPK).
- The design, construction, testing and supply of a ground based acoustic system to detect wheel flats and bearing faults of railway rolling stock (Australian National).
- Design and testing of Hercules C-130 rear wing flaps for acoustic fatigue.
In 1998 Ben completed his PhD thesis titled
"Sensing systems for active control of sound transmission into cavities" with the Active Noise and Vibration Control Group
at the University of Adelaide, South Australia.
Whilst undertaking postgraduate and post-doctoral research he was also
involved in numerous consulting projects in conjuction with MechTest Pty Ltd, University of Adelaide:
- Vibration measurements and fault diagnosis on a diesel generator set (Cavpower).
- Sound intensity and sound power measurements on an electric motor (Pope Electric Motors).
- Sound power level measurements in a reverberant chamber (Dadanco).
- Compliance testing of gymnastics equipment (Acromat).
- Design, installation and testing of an active noise control system for an exhaust stack (Adelaide Brighton Cement)
- Reactive silencer design for an exhaust stack (NAP Silentflo).
- Sound Transmission loss measurements of fire wall materials (Mitsubishi Motors Australia),
acoustic insulation (Tontine Industries) & rubber panels (bounce-back).
- Insertion Loss measurements of flexible ducts (DuctAir).
- Vibration Condition Monitoring and fault diagnosis of electrical motors (Pope Electric Motors).
- Telescope truss design using FEA (Dept. of Physics, University of Adelaide).
In 2000 Ben was awarded an Anglo-Australian PostDoctoral Fellowship by the Royal Academy of Engineering
to undertake research into Optimal Focusing of Underwater Acoustic Source Arrays. From the press release "Beating the dolphins at their own game":
Five more young research stars from Australia have won Anglo-Australian
Postdoctoral Fellowships to work for a year at British universities and
research institutions in the second year of a Government scheme covering
engineering, science and the social sciences. The programme is funded
through the UK Office of Science & Technology and the Australian Research
Council finances a reciprocal arrangement for UK researchers to go to
The Royal Academy of Engineering, with support from the Royal Society and
the British Academy, selected the successful candidates from among 64
applications. Three researchers were appointed to the first round of
fellowships in 1998.
Dr Ben Cazzolato, 30, an acoustic engineer from the University of Adelaide,
will spend a year working with Philip Nelson, Professor of Acoustics at the
University of Southampton. Cazzolato will study new signal processing
techniques to avoid distortion of active sonar signals. Sound travelling
underwater often suffers from reflections from both the ocean surface and
the sea bed. Southampton's Institute of Sound & Vibration Research is
collaborating with the Defence Evaluation and Research Agency at Winfrith to
solve this problem. They aim to use inverse filters to compensate for the
distortion, preserving even a signal transmitted by an array of sources.

Ben commenced employment with the University of Adelaide in 2001 as an academic. He is currently teaching two control automatic control subjects; Dynamics and Control II and Advanced PID Control. Dynamics and Control II is focussed on understanding and controlling dynamic systems from a state space perspective. Advanced PID control, as the name suggests, is focussed on developing PID control skills within a theoretical and practical framework.
One key interest for teaching is the development of physical platforms to demonstrate control theory. These include the Quanser Aerospace Systems, the Ball and Beam System, the Quanser Tightrope Walker, the Inverted Pendulum, and many others.
Honours Design Projects
Each year, honours students in the School of Mechanical Engineering undertake a Design Project of approximately 400 hrs.
These projects typically involve some degree of research and risk, but are also a lot of fun.
Some of the recent projects supervised by Ben are listed below:
For a complete list of past projects, please see the School's Design Project Webpage.
