Structured Sessions:

Structured Sessions are organised by scientists of acknowledged reputation who define the scope of the sessions, personally invite authors, review abstracts of contributed papers, schedule the papers, and finally chair the sessions.

  • S01 Acoustic and dynamic properties of composite and sandwich materials
    • Anders Nilsson
    • During the last few decades various types of lightweight structures have been integrated in many types of vehicles. The trend is dictated by demands for a higher load capacity for civil and military aircraft, reduced fuel consumption for passenger cars and busses, increased acceleration and retardation for trains to increase average velocity. The dynamic response and the coupling to fluids of these structures is very different from that of traditional steel or aluminum plates. Reliable prediction models must be developed and methods for incorporating these models in traditional FEM, BEM and SEA calculations are needed. Further, techniques for determining the material parameters of any type of composite structure must be developed and standardized.

    • Björn Hellstrom
    • A high-quality urban sound environment cannot be measured only in decibels. Just like with everything else around us, it?s a matter of the overall perception and the total experience. In the acoustic landscape, the subjective sound quality is therefore as important as the objective sound level. The purpose is to develop deeper knowledge on sound design as part of architectural and urban space, and to open for interdisciplinary modes for analyzing and understanding the sonic environment, where acoustics is integrated with architectural design methods. This may include social and cultural dimensions as well as visual and tactile architectural aspects when designing a sonic environment, i.e. forming sound qualities in reference to actual situations. In an urban context it may address issues on how to bring forth sonic spaces that support activities taking place, or improve possibilities for comprehension or positive experiences of a site. The aim is also to develop knowledge that can strengthen the communication between architects, acousticians, urban planners, developers and other actors involved in urban planning and design processes. Key concept is: urban sound quality.

They are a complicated phenomenon that is not yet fully understood. Yet, a good understanding of the underlying physical mechanisms is essential to design robust combustion systems and to develop effective control strategies. The aim of this structured session is to bring together scientists with an academic and/or industrial background in this area.

  • S19 Friction Induced Vibrations
    • Alaa El-Butch
    • Friction-induced vibrations and sound occur in our everyday life, the examples of friction-induced vibrations and sound cover numerous phenomena in science and engineering. Brake squeal in automobile and motorcycle, wheel squeals of rail vehicles in narrow curves, elevator rail roller squeaks, robotic joint squeaks, chattering of machine tools, creaking of door hinges are some forms of friction-induced vibrations. Modeling of friction-induced vibrations and sound in mechanical and other systems requires an accurate description of friction. Unfortunately, there is no universally accepted friction model or theory to cover general friction phenomena. On the other hand, the resultant vibrations often exhibit various nonlinear, transient, and unsteady features; the resultant sound is usually non-stationary with a range from tens of hertz to ultrasonic. Papers on modeling, analytical, and experimental investigation are welcomed to cover substantial progresses in the field of friction-induced vibrations.
  • S20 Intelligent Active Control of Noise and Vibration
    • Osman Tokhi
    • The purpose of this session is to report on the latest findings and developments at the theory and practice levels of modelling and control strategies for active noise reduction and vibration suppression using intelligent techniques. Adaptive control techniques with conventional optimisation/learning algorithms have proven to be effective in a range of practical applications. Recent developments in soft computing strategies at modelling and control of dynamic systems have demonstrated their potential benefits in solving problems of highly complex nature. One aspect in this context is a diversion into model-based and non-model based control. The latter is very attractive in cases where development of a system model proves to be complex, and such opportunity is provided with suitable soft-computing approaches. Contributions reporting the latest research and/or development works in areas of active control of sound and vibration incorporating (but not limited to) traditional adaptive methods, computational intelligence and soft computing approaches involving neural networks, fuzzy logic and biologically-inspired optimisation strategies such as genetic algorithms, particle swarm, etc. are invited for possible inclusion in this session.

Artificially intelligent methods of diagnostics and prognostics can be included, for example based on artificial neural networks, fuzzy systems etc.
  • S23 Mid-Frequency Methods in Noise and Vibration Analysis
    • Brian Mace
    • The “mid-frequency” regime brings special problems for the noise and vibration engineer. Typical applications, the audio-frequency range for automotive and aerospace structures, for example, are not amenable to either finite element analysis alone (the model is too large, perhaps, or the model parameters uncertain) or statistical energy analysis (some subsystems may have few modes, for example). This mid-frequency gap in our modelling capabilities provides the motivation for new methods of analysis, often involving hybrid approaches combining finite element analysis, energy methods, statistical energy analysis and wave approaches, together with deterministic and/or stochastic modelling. Such methods are the subject of this structured session.

  • S31 Nonlinear Acoustics and Vibration
    • W S Gan
    • Nonlinear acoustics and vibration is a study of large amplitude sound waves and vibration.

Applications are very broad and include nonlinear nondestructive evaluation, harmonic medical ultrasound imaging, high intensity focused ultrasound for noninvasive surgery, cavitation, drug delivery and gene therapy. With the rise of biotechnology and nanotechnology, nonlinear acoustics is becoming more important since it can be applied to these two large fields. Even in theoretical studies, nonlinear acoustics find relevance in the growing importance of chaos theory and turbulence. Chaos has become a popular area of resaerch during the last twenty years with the establishment of institutes of nonlinear science and complex systems at many universities and research centres and with journals dedicated to the subject. Chaos can be found to have applications in fluid dynamics such as turbulence, nonlinear dynamics and multiple scattering phenomena. Turbulence is the last unsolved problem in classical physics and has been listed by Cray Institute as one of the ten unsolved mathematical problems.

  • S35 Shunt damping technology for noise and vibration control
    • Stanislaw Pietrzko
    • This structural session presents the latest results in the field of shunt damping technology for the purpose of attenuating sound transmission, sound radiation, and vibration. Passive vibration damping with viscoelastic material treatment has reached a point at which the physical limitations disallow significant progress. A lot of research on damping in recent years has been devoted to the development of new innovative concept known as shunt damping technology. The goal of this approach is to control and maximize the dissipation of disturbing vibrating energy in wide frequency ranges using active piezoelectric materials (patches) or electrodynamic systems (actuators, loudspeakers) shunted by an active or passive electronic circuit. When the structures vibrate, the piezoelectric patch strains and transforms the mechanical energy of the structure into electrical energy, which can be effec-tively dissipated by the shunt electronic circuit. Hence, the shunt circuit acts as an additional damping element, extracting mechanical energy from the base structure. Examples of such systems include: online-tuned resonant shunts that automatically adapt themselves so that optimal vibration suppression is achieved for one or several modes and a new autonomous shunt circuit that does not require external electrical power for operation because it utilizes the power harvested from the vibrating structure itself. The use of shunted circuits has great promise in the control and minimization of sound power radiation from vibrating structures and sound transmission trough vibrating walls. Your paper is a welcomed contribution to this important innovative research field and is appreciated immensely.

  • S46 Vibration and Acoustics of Periodic Structures
    • Jihong Wen
    • Vibration and acoustics of periodic structures is a subject of continuing interest. One reason is that many engineering structures can be treated as periodic, such as multi-storey buildings, multi-span bridges, multi-blade turbines, stiffened plates and shells, trusses and truss-core structures. The vibration and/or noise levels of these structures must be taken into account. Another reason is that periodic materials or structures, often referred to as phononic/sonic materials/crystals in recent years, exhibit fascinating frequency-banded properties, which is of great interest in the area of vibration and noise control. This structured session is intended to provide a forum for specialists in vibration and acoustics of periodic structures or composites to exchange their experiences and research ideas.

  • S47 Vibration Testing and Monitoring of Structures
    • Mohamed Abdelgawad
    • One of the important fields of applications of vibration testing is structural assessment and monitoring using vibration measurement data. Large structures need for condition assessment and monitoring for maintenance planning and load rating. Although many testing methods exist to serve structural engineering, most of them give reliable information only about the point or area where the measurement was made. Vibration and modal testing are of the few methods which can yield useful information about the structure as a whole. Usually the method is used to estimate structural frequencies, mode shapes and damping ratios. These dynamic characteristics of a structure when deduced from measurements are later used to fine tune finite element and numerical models of the structure. Also they are used to realize physical changes in the structure by monitoring the change in them. Many attempts are being conducted to define the location, type and extent of damage through analysis of these measurement derived parameters. The need for more research in the above mentioned areas is of major importance. Also the addressing of the different technologies and methods including ambient vibration monitoring (AVT), modal testing using shaking devices, sensors and measurement systems incorporating wireless technologies, and laser vibrometry is main importance in modern structural engineering.

  • S49 Vibro-acoustics in Buildings
    • Barry Gibbs
    • This session will consider methods of measuring and predicting structure-borne sound in buildings due to mechanical services systems and domestic appliances. The mechanical services include: heating and ventilation systems, piped water systems, internal transportation systems and stair systems. Domestic appliances include: central heating units, washing machines and cleaning and food processing appliances. Until recently, the complexity of the structure-borne sound transmission and propagation process has prevented the development of measurement and prediction methodologies of use to manufacturers, building engineers and legislators concerned with noise control. However, there has been progress in the prediction of noise resulting from impact and vibration sources in heavyweight homogeneous building structures. There also has been some progress for the case of lightweight non-homogeneous constructions. This session welcomes papers on vibro-acoustic source characterisation and on methods of predicting the resultant sound pressure levels in buildings. The session will be of interest to researchers who are developing laboratory test procedures for characterising sound sources and also the transmission characteristics of walls and floors, including impact sound; also, for those implementing recently introduced standard prediction methods for airborne and impact sound transmission between rooms. Papers on the performance of lightweight constructions are particularly welcome.
