Summary of FIFTH INTERNATIONAL CONGRESS ON SOUND AND VIBRATION *********************************************************************************************************** The Fifth International Congress on Sound and Vibration was attended by more than 400 delegates The University of Adelaide, South Australia was proud to host the fifth in a series of congresses which began in 1990 at Auburn University, USA under the guidance of Professor Malcolm J. Crocker, and which now are sponsored by the International Institute of Acoustics and Vibration (IIAV). By all accounts, the Fifth Congress, held from December 14-18, 1997, was a resounding success, both in terms of the technical program and social events. For the first time in the congress series, the Fifth congress introduced a series of six two-hour educational tutorials on recent advances in acoustics: "Active Noise Control" by Professor Osman Tokhi, "Dynamics of Vibro-Impact Systems" by Professor Vladimir Babitsky, "Sound Intensity" by Professor Malcolm Crocker, "Statistical Energy Analysis" by Professor Ken Heron and Paul Bremner, and "Wavelets" by Professor David Newland. All tutorials were well attended and certainly added educational value to the congress. Another first was the introduction of specialist keynote presentations which were used to introduce the state of the art of the subject of 15 different special sessions. The specialist keynote presentations occupied two time slots at the beginning of the particular session they introduced and were very well received. Also for the very first time, the Fifth Congress was held jointly with another conference which in this case was the 1997 Annual Meeting of The Australian Acoustical Society. The compact campus of The University of Adelaide, located in the heart of downtown Adelaide was the ideal venue for a congress of this type; lecture theatres and tutorial rooms provided high quality venues for the technical presentations and the grand old Elder Hall provided a wonderful venue for the opening and closing ceremonies as well as for five of the seven distinguished keynote addresses. All of the eight parallel sessions were housed in the same building together with the equipment and services exhibition which featured 19 different companies. Accommodation was within a short walk of the Congress venue which was close to restaurants entertainment and shops. The Fifth Congress began with a reception at the University which was held on the Sunday evening at 6:00pm on the lawns surrounded by the University cloisters. Registration of delegates began on Sunday afternoon and continued early on Monday morning after which the Opening Ceremony began in the magnificent Elder Hall at 9:00am. Delegates were welcomed by the Congress General Chair, Dr. Colin Hansen, The Vice Chancellor of The University of Adelaide, Professor Mary O'Kane and the South Australian Minister for Environment and Heritage, The Right Honourable Dorothy Kotz who opened the Congress. After a magnificent vote of thanks by Sir James Lighthill, delegates were entertained by Megan Tucker, a beautiful and talented soloist. Immediately following the Opening Ceremony, Sir James Lighthill entertained and educated the audience with his opening Presidential Address, "A Century of Shock Wave Dynamics". Other istinguished plenary keynote addresses which were presented at various times throughout the Congress were: "Into the Physics of Rotor Aeroacoustics: Highlights of Recent European Helicopter Noise Research", by Dr. Hanno Heller; "Recent Developments in Acoustics and Vibrations", by Professor Malcolm J. Crocker; "Recent Advances in the Active Control of Structurally Radiated Sound", by Professor Chris Fuller; "Vibration Suppression through Smart Damping", by Professor Dan Inman; "Developments in Digital Analysis Techniques for Diagnostics of Bearings and Gears" by Professor Bob Randall; and "Hearing Protectors" by Professor Samir Gerges. There was one distinguished keynote address every morning and afternoon of the four days of technical sessions, except for the final afternoon. Following each distinguished keynote address were eight parallel technical sessions, so that there was one series of parallel technical sessions each morning and afternoon of the congress, except for the last day. In all, over 300 technical papers were presented during the four days of the congress. In the evening of the first day of technical sessions, delegates were treated to a complimentary BBQ and entertainment at Cleland Wildlife Park, where delegates roamed among the friendly kangaroos and koala bears. One of the many highlights of the evening was the didgeridoo performance by a local band. The fourth evening was set aside for the congress banquet, a grand affair which took place at the Stamford Grand Hotel, adjacent to the beach. The dining room which easily housed all 350 guests was actually a ballroom with a balcony which faced the setting sun. The evening was warm and balmy and many delegates enjoyed watching the sunset through the open doors to the balcony as they ate their first course. Transport to the banquet was by champagne-filled heritage electric tram carriages hired exclusively for the congress participants. The banquet formalities began with a welcome by Dr. Colin Hansen who also introduced Professor Malcolm Crocker as the MC for the evening in control of the various awards and entertainment. The highlights of the evening included the presentation of the first IIAV Honorary Fellowship to Professor David Crighton, and the presentations made by Dr. Ravi Margasahayam, from the NASA Kennedy Space Centre in Florida. He presented Professor Mary O'Kane, the Vice Chancellor of the University of Adelaide with a mounted photograph of the latest space shuttle launch which was signed by all of the crew. He then presented a similar photograph to Dr. Colin Hansen for the Department of Mechanical Engineering as well as a personally signed photograph of Dr. Andrew Thomas in the space shuttle. This last gift was of particular value to the Mechanical Engineering Department at the University as Dr. Thomas graduated with both an ordinary degree and a Ph.D. in that Department. Following lunch on the fourth day of technical sessions, the Closing Ceremony was held. Dr. Hanno Heller, the General Chair of the Seventh Congress presented an exciting video on the locality of the Congress to be held in Garmisch-Partenkirchen, Germany on 4-7 July, 2000. He extended a warm welcome to everyone present to attend and experience some traditional Garmisch hospitality. The Closing Ceremony ended with a delightful presentation by Dr. Finn Jacobsen, the General Chair of the Sixth Congress to be held at The Technical University of Denmark in Copenhagen, Denmark on 5-8 July, 1999. He presented some wonderful slides of the proposed congress venue and surrounding area and issued a warm invitation for all delegates to attend. The dedication and hard work of the Organizing Committee and many members of the Scientific Committee, and the welcome advice and assistance from Malcolm Crocker, resulted in an enjoyable and successful congress and deserve special thanks and appreciation. _________________________________________________________ Dr. Colin H Hansen Reader and Head, Department of Mechanical Engineering The University of Adelaide South Australia 5005 AUSTRALIA ph. +61 8 8303 5698 fax. +61 8 8303 4367 e-mail: chansen@mecheng.adelaide.edu.au *********************************************************************************************************** ITEM 4.

RESEARCH ON ACTIVE STRUCTURAL CONTROL IN THE UNIVERSITY OF L'AQUILA, ITALY *********************************************************************************************************** The research activity on active structural control at the Dipartimento di Ingegneria delle Strutture, delle Acque e del Terreno in the University of L'Aquila is focused on the understanding of the complex dynamical interaction between structural systems and a series of control devices, such as active mass dampers and active cables, and to utilize the intricacies of this interaction for the purpose of reducing environmentally-induced oscillations in slender and flexible structures. Some analytical and numerical results have been obtained and published in the last two years regarding the analysis of the complex nonlinear dynamics of a suspended cable with a longitudinal control displacement applied on one support. Linear and nonlinear feedback control laws have been designed and compared, depending on cable sag parameter, in terms of control effectiveness and energy demand. Particular attention has been devoted to bifurcated out-of-plane oscillations, due to the parametric resonances of the in-plane load. These results have been used to investigate the possibility of actively controlled cable-supported beams. Here, the analysis on the effectiveness of longitudinal control on free and forced in-plane oscillations and galloping type instability have been exploited. Some of this activity is still in progress. On the other hand analysis of the active mass damper system has been considered, in particular regarding the problem of controlling flow-induced oscillations and related interaction phenomena. An adaptive control technique has been developed for uncertain nonlinear dynamical systems representing flow-induced oscillations of an immersed cylinder in the presence of the vortex phenomena. This research has been conducted in collaboration with Prof. Ghanem of the Johns Hopkins University at Baltimore. Still in progress is the analysis of the effect on the post-critical behaviour of a tuned mass-damper system undergoing galloping and vortex-induced instabilities. Plans for the implementation of a series of instrumented laboratory experiments on light models have been made and these will receive partial support from the Italian Ministry of Scientific Research (MURST).

DANISH DEFENCE RESEARCH ESTABLISHMENT (DDRE) *********************************************************************************************************** The Danish Defence Research Establishment (DDRE) conducts research in several areas related to the Danish Defence. One of the important areas is acoustics in which some of the main subjects are: 1) Propagation of acoustical noise over terrain and the sea. 2) Acoustical location of small arms fire. 3) Sound and vibration measurements related to weapons, vehicles and aircraft. 4) Environmental noise calculations based on military operations. My work is mainly concentrated on the two last subjects mentioned and the reporting that is associated with them. Most tasks concerning environmental noise measurements and calculations in Denmark have been nationally standardised. Laws and guidelines have been elaborated by The Danish Ministry of the Environment in close co-operation with experts in the particular field. These guidelines are available as books/booklets. The Danish Ministry of the Environment has recently published a new booklet in this series, which describes the way noise immission from the Danish target ranges should be calculated. This guide does not describe which formulas to use in the calculations, but merely says that one of two calculation programs should be used to solve the task. The programs mentioned are the German LARMLAST and the Danish FOFTlyd (developed by DDRE, DDRE=FOFT in Danish), which are both capable of providing results such as Lc,den noise contours based on events occurring during one year. FOFTlyd is an 1/1 octave band model which uses the common Nordic propagation model; but the model has been modified by adding the octave bands 16Hz and 31.5Hz, which are the octave bands where most of the sound energy from large caliber weapons is located. Furthermore there is implemented a linear attenuation coefficient of 0,8 dB/km which has been shown to give results comparable to measurements performed by CERL in the US. FOFTlyd is also capable of taking the sonic boom from supersonic shells into account. Denmark is a small country with relatively short distances involved which makes noise nuisance in general an ever-growing problem. Furthermore the Danish Defence involves only relatively small land areas and in some of the smallest target ranges only "fire crackers" and small caliber weapons are used. This, as I understand it, is reflected in the fact that the noise immission from target ranges in Denmark includes emission from weapons with a caliber below 12,7 mm. OCCUPATIONAL NOISE EXPOSURE IN THE DANISH DEFENCE In a similar way the Danish Ministry of Labour has elaborated laws that limit the noise exposure in a place of work to minimise the risk of suffering a permanent hearing loss. The current limits in Denmark are 85 dB(A) equivalent noise level during an 8 hour working day and a maximum linear peak noise level of 140 dB. The Danish Defence, like other defences, trains and educates men and women. Investigations have shown that during the proper military education and training it is practically impossible to attenuate loud sounds, such as vehicle and especially shooting noise, enough to meet the demands of the law. Dispensation, especially in areas concerning education, has therefore been granted to the Danish Defence. The military in other countries experience the same noise levels and therefore the personnel involved have a potential risk of suffering permanent hearing loss. ENVIRONMENTAL NOISE IN DENMARK In Denmark, as well as other countries, there are complaints from citizens concerning infrasound /low frequency noise. The complaints are mostly concentrated in an area about 40-km northwest of our capital Copenhagen. In this area a major power plant, a steel factory and a large target range are located, all of which are potential low frequency noise sources. Several experts have been involved in measuring the phenomena, but all of them have had trouble correlating the measurements with the response of the individuals. The citizens mentioned have started a group called "The Enemies of Infrasound", and their newest theory about the source of their nuisance is that it is underground gas pipes, which they believe vibrate and transmit sound. It has yet to be determined whether the citizens complaining have abnormally good hearing or not. Investigations in other countries have not been able to pinpoint the noise source(s) either.

RESEARCH: Vibration and Acoustics Research in the Measurement and Control Engineering Research Center at Idaho State University *********************************************************************************************************** The Measurement and Control Engineering Research Center (MCERC) at Idaho State University (ISU) is in the process of completing a new structural dynamics and controls laboratory. This new facility will significantly enhance the vibration and acoustical testing capabilities at ISU. Two areas of current research at the MCERC are the development of an Electro-Optic Holography (EOH) system and active control of vibrations and acoustical phenomena using a technique called iterative learning control. EOH is a whole-field, laser-based, electronic holography technique used to measure micron sized displacements in vibrating structures. EOH relies on specular interference of coherent light to obtain optical phase differences between interfering waves in terms of intensity. These interference or fringe patterns are recorded by a CCD camera. Recent developments with researchers at NASA Langley Research Center have led to novel ideas which allow the relative phase of adjacent particles to be determined where before the results were limited by time averaging techniques. With the ability to extract the structural phase, power flow or structural intensity can be measured. One goal of this research will be to develop control techniques using power flow as the measured control parameter. This will allow control techniques to be developed which will channel or dissipate the energy in the structure as desired. Other uses of the EOH system will be to characterize the dynamic response of MEMS and the dynamics of rotating bodies. One of the techniques that will be investigated for power flow control is called iterative learning control (ILC). ILC is an intelligent control methodology for repetitive systems. Each time the system executes one cycle of a trajectory the output error is used to update the control signal for the next cycle. The technique allows the controller to implement a pseudo non-causal algorithm which can improve tracking performance and disturbance rejection. Initial investigations in the new MCERC lab are applying some theoretical ILC results to the problem of acoustic noise cancellation in ducts. Future plans are to use ILC to shape the power flow in vibrating structures, using EOH as the key measurement technique. **************************** Jonathan D.

READERS' QUESTIONS ********************************************************************************************************* Paul Shuter, a Masters Degree student in Industrial Engineering at the University of Louisville, is investigating the possibility of an acoustic monitoring and warning system for a robotic welder. Since sight is not an aid in robotic welding, he has chosen to pursue sound as a monitoring tool, the essence being that welding sounds can be categorized from good to poor. Each good sound can degrade in various ways: nozzle conditions, wire feed, and other factors that can change even if everything is numerically controlled. The controller would have a comparator which would alert the machine operator when the machine "goes out of tune" (similar to the way a guitar tuner works but in reverse). The operator can then evaluate and correct the machine, minimizing downtime and scrapped parts. Anyone who is working on this topic or who is willing provide information is requested to contact Mr. Shuter by e-mail at MLSHUTO1@homer.louisville.edu. *********************************************************************************************************** ITEM 15.
