If you have read a technical paper on road noise in the last 15 years there is a fair chance James McIntosh either authored it or is cited in it. James spent 20 years at GM Holden, working on noise and vibration harshness is vehicle development before running the Crash Test Lab (which sounds like fun to me). He then moved to VicRoads, the Victorian government roads department, and was responsible for the development of much of the noise policy over his time there. In 2021 he left his government role and set up his own consulting firm James McIntosh Acoustics.

The architectural perspective on the interaction between acoustics and the built form learning environment from Hayball's Fiona Young. An immersive adventure about an acoustician and a team of architects going back to school to run a project based learning exercise with year 7 students at Domremy College, thanks to principal Vivienne Awad. 

After completing a degree in physics, Marion Burgess commenced working in acoustics in an Australian building research laboratory. Since then she has had over 40 years broad experience in many aspects of acoustics including building, environmental and occupational noise measurement, assessments, control and research.

Katie is a specialist in the technical field of environmental acoustics associated with mining, industry, roads and railway transportation. Katie manages the acoustics team for EMM in Newcastle, Australia. She is passionate about education and mentoring others in acoustics.

Joanne Valentine started out studying architecture and with Harold Marshall as a lecturer, quickly developed a passion for room acoustics. She has followed that passion for over 30 years, working on the acoustic design performing arts projects around the world.

Rick Bond is a speaker builder from Melbourne Victoria and his company Lucie Audio not only builds speakers but also a matching DSP-based audio processor to apply room corrections to the system in real time.

Meisha Stevens is a consultant with Wood & Grieve, based in Sydney who has an interest in psycho-acoustics and how we react to unpleasant sounds. She was this year awarded the Future Leader Award by the National Association of Women in Construction.

This episode is a recording of a presentation delivered by Sir Harold Marshall as part of a colloquium on Presence that took place in Auckland in July 2018. The presentation is entitled 'The Oblique Imperative: the acoustic dimensions of presence'.

Jos Mulder lectures in Sound at Murdoch University in Perth, WA. How do you get a great acoustic concert hall to sound good amplified? And what can we do to save the hearing of musicians and concertgoers?

Marcia Isakson is the immediate past president of the Acoustical Society of America. She went to West Point and served in the military before moving into research and teaching in underwater acoustics, and currently works with the University of Texas in Austin. She has a passion for attracting more women into the field and has works with the Women in Acoustics committee as part of her work with the ASA.

John Meyer, along with his wife Helen, foundered one of the worlds leading audio technology manufacturers, Meyer Sound in the 1970's. They have an emphasis on research and development which in recent years has seen the development of the Constellation active architecture system. I sat down with John recently and talked about everything from active acoustics to AM radio.  

Christopher Allen works for NASA as Manager of the Johnson Space Centre Acoustics Office. He works on the acoustics of space vehicles and faces some pretty interesting challenges that you don't have to deal with on earth.
