  Paper Title: Industry and University partnerships in Acoustic Research - Factors for success
  Abstract: Cooperation between industries and universities takes many forms - adhoc or regular consultancies, work experience projects that may extend over several years, student project sponsorships, long term research and development contracts usually involving post graduates, and partnerships through cooperative research centres. This paper presents a brief review of the nature and extent of University industrial partnerships in Australia in the area of acoustics; assessed against longevity, income, postgraduate numbers, benefits to partners, and the development of research critical mass. It gives a detailed discussion of cooperative partnerships in the areas of services and product development against a background of Government and industry priority research areas, and Government research and development incentive programs. Case Studies will be used to illustrate the various fundamental attributes and structures for growing and sustaining successful working relationships.

  Paper Title: Acoustical Properties of Ancient Chinese Musical Bells
  Abstract: Ancient Chinese music bells can be traced back to the Shang dynasty (1600-1100 B.C.). In addition to their significances in history and metallurgy, Chinese music bells also have important contribution to acoustics due to their unique acoustical properties and rich physical mechanisms involved. They differ from carillon/church bells and oriental temple bells by their almond-shaped cross sections, which acoustically result in two distinct striking tones, and short decay time. The interval between the two strike notes is often tuned to be minor third and that between adjacent bells is major third. In this paper, we demonstrate (1) such tuning in and between bells allowed the performance of twelve semitones in one octave; (2) effective sound radiation of the vibration mode associated with the bell's cross section is the mechanism of the short decay time; (3) balance of loudness of the music bells is achieved by scaling of bell's dimensions and additional thickness scaling rule for the high frequency bells.

  Paper Title: Sense from Sensing Sound
  Abstract: Smart acoustic surveillance systems are unattended in their operation and are often deployed in remote areas for the automatic detection, localization, classification and tracking of military activities, which are inherently noisy. Acoustic sensors are appealing because they are passive, affordable, robust, and compact. Methods, with examples, for extracting tactical information from acoustic signals emitted by moving sources (air and ground vehicles) are presented. The methods are based on processing either the narrowband or broadband spectral components of the source's acoustic signature. To demonstrate the scientific principles that underpin the operation of such systems, various signal processing algorithms are applied to real acoustic data from both single and multiple sensors. In one example, the acoustical Doppler effect enables the flight parameters and blade-passage frequencies of turboprop and rotary wing aircraft to be estimated from the time-frequency signal analysis of acoustic data. In the case of a transiting ground vehicle, reliable estimates are provided for the speedometer reading, odometer reading, number of cylinders and range at closest point of approach of the vehicle to the sensor. For wideband processing leading to source motion parameter estimation, phase transform prefiltering is required to suppress the ambiguous peaks in cross-correlograms caused by the presence of strong narrowband lines in the source spectra of air and ground vehicles. In another example, the acoustical Lloyd's mirror effect is used to extract the flight parameters of a jet aircraft. Wideband cross-correlation with differential Doppler compensation is required for the acoustic tracking of high-speed broadband sources such as jets when the sensors are widely separated. Also, weapon firings generate acoustic muzzle blast waves and supersonic projectiles generate ballistic shock waves that propagate in air with spherical and conical wavefronts, respectively. When these wavefronts traverse an acoustic sensor array, the sensor output data are processed to locate the point-of-fire, together with the miss distance and calibre of the bullet. The methods developed for land-based acoustic surveillance using microphone data are also applied to hydrophone data for passive acoustic surveillance of the underwater environment.

  Paper Title: Advanced Passive Treatment of Low Frequency Sound and Vibration
  Abstract: It is well known that standard poro-elastic materials and visco-elastic damping materials are ineffective at reducing low frequency sound and vibration. This paper overviews two new treatments developed at Virginia Tech which attempt to address this problem. HG material consists of poro-elastic material with embedded multiple small masses. The masses combine with the natural elasticity of the poro material matrix to create multiple vibration absorbers with a range of tune frequencies in the low frequency region. The embedded masses are found to significantly increase the low frequency transmission loss and absorption of the poro-elastic material. DVA's are vibration absorbers whose active mass and spring are spread over a large area while still maintaining a viable damped reactive effect at low frequencies. DVA's are found to provide global reduction of low frequency vibration of structures in a compact, lightweight configuration. DVA's are also observed to provide mid to high frequency damping most likely to air squeeze damping effects. The paper will overview the concepts, development and testing of both devices. Applications of the new treatments to realistic structures will be considered.

Social Program

Sunday Evening 22 November	Reception at National Wine Centre, Adelaide The Wine Centre is located on the corner of North Terrace and Hackney Road, a short pleasant 15min stroll east (towards Hills, past Botanic Gardens) along North Terrace from the University of Adelaide.   All guests are welcome to go on a self-guided/interactive Wine Discovery Journey at the Wine Centre (up the ramp in the foyer) from 5:00pm.  Note that Registrations for the conference will also be done in the Wine Centre foyer from 5:00pm.   From 6:00 to 8:00pm, a Cocktail Function will be held in the great Hickinbotham Hall of the Wine Centre, featuring superb SA wines from 6 wine regions, including Barossa Valley, McLaren Vale, Clare Valley, Coonawarra, Langhorne Creek and Adelaide Hills, along with selections of gourmet canapes. The Young Adelaide Voices ('Aurora') will provide an atmospheric choir performance in the tremendous acoustic space of the Hall at 6:30pm.
Monday Evening 23 November	Banquet at The Stamford Grand, Glenelg Beach by heritage tram
Wednesday Afternoon 25 November	Close of conference drinks and barbeque at the conference venue

In Adelaide’s compact city centre, all facilities, from the convention venue and hotels to cafés and nightclubs, are conveniently clustered within walking distance of each other.

Adelaide makes an ideal launchpad for visits to the Barossa, McLaren Vale and Clare wine regions, the far north “outback” regions of South Australia, and the pristine Kangaroo Island; one of the world’s last unspoiled wildernesses.
