David Bies Prize in Acoustics

In recognition of the contributions of David Bies to the science and practice of and education in acoustics, the South Australian Division of the Australian Acoustical Society has resolved to establish a Prize to recognise outstanding contributions in these areas.

The Prize shall be made available each year and may be awarded to a member(s) of the Australian Acoustical Society who is/are an acoustical practitioner(s) in South Australia, or has/have made a meritorious contribution to the discipline in South Australia.

Invitations for nominations for the prize shall be published in the first issues of Acoustics Australia each year, and in appropriate notices to South Australian members of the Society. Determinations of the recipient(s) of the prize shall be made by the Committee of the South Australian Branch of the Society, which may consider. any relevant information. Decisions of the Committee shall be final. If the Committee determines that no nomination merits award of the Prize it will not be awarded in that year. If a member of the Committee is nominated for consideration for the award then he/she shall not take any part in the determination process.

The Prize shall take the form of a suitably inscribed object of some elegance to the value of approximately $200. The inscription shall take the form: The David Bies Prize, presented to --- in recognition of an outstanding contribution to acoustics in South Australian in --(year)-- A pewter plate or plaque is recommended in the first instances, but an acoustically-related item may be preferable to suit some recipients.

The Chairperson of the S.A. Division (or delegate) shall present the Prize at a suitable function to which relevant dignitaries from Industry and the Community and media representatives may be invited.

Nominations can be made via written correspondence to the AAS SA Division.

Previous winners of the David Bies Prize are:

1998Prof. Colin Hansen

Colin received his prize for his outstanding contributions in Acoustics and Vibration to professional, academics and students.
1997Dr. David Rennison

David received his prize for his work on the redesign of the C130 Hercules aircraft.
1992Dr. Peter Swift

Peter was the recipient of the inaugural David Bies Prize for his work on a dissipative silencer for pipeline blow off valves. His ingenious patented design met the needs of the pipeline industry and has become a commercial success.

The innovative range of multi-stage non-absorptive blow-off attenuators was originally developed during the mid 1980's by Peter Swift a director of Pryce Goodale and Duncan (now Bassett Consulting Engineers) to reduce high pressure gas blow off noise to safer levels in the Moomba to Adelaide natural gas pipeline in South Australia.

The attenuators are currently in service in several Australian states (SA, WA, Qld, NSW) and interest from overseas has been expressed.

The high pressure blow off attenuators are of simple (acoustic) design, they are relatively small, inexpensive and capable of providing high attenuation (25dBA noise reduction at 10m from source).

Whereas for conventional attenuators the performance is inadequate, or alternatively their size, complexity and cost are excessive, attenuation varies with gas flow, and deterioration of absorption material is a problem.

The attenuation afforded by the attenuators not only assists in reducing environmental noise but more importantly helps to avoid the risk of severe hearing damage as unattenuated noise levels of between 140 and 150 dBA at 1m have been measured during automatic gas blow off (which may occur without warning).

The attenuator design is not restricted to gas alone but is also effective with air, steam and other dischargeable gases. The attenuators are designed, developed, manufactured and tested in Adelaide, South Australia.

Post Graduate Travel Grants

The aim of the society is to 'promotion and advancement of the science and practice of acoustics in all its branches and the exchange of ideas in relation thereto'. The SA Division offers a $1000 grant to SA Division members of the AAS that are undertaking post-graduate study in acoustics or vibration, to supplement the cost of attending the annual AAS Conference. Applicants for the grant should send a formal letter to the Division Secretary that will be considered by the SA Division committee containing the following:

  • Name
  • Title and abstract of the conference paper that has been submitted to the annual AAS Conference
  • Any correspondence from the conference organisers acknowledging the receipt and acceptance of the paper

Outstanding Undergraduate Student in Acoustics Prize

To encourage the undertaking of acoustics as a career, the SA Division will offer a prize of $500 to an outstanding student of acoustics. The student does not need to be a member of the society.
