List of the Structured Sessions:
|T01 SS1||Sound and Vibration Measurements and Analysis|
The purpose of this structured session is to report on the latest research and development works carried out in the field of sound and vibration measurements, and analysis. Papers presented in this session can focus on experiments carried out in research laboratories or in practical installations in vehicles or in industrial applications, etc. The papers can, for example, treat sensor technology, transducers that actually consists of a combination of sensor/sensors and signal processing for sound and vibration measurements, measurement and analysis of sound and vibration in new applications areas or in challenging applications. Papers may also concern new norms concerning sound and vibration quantities and their purpose, and new or useful information and/or quantities extracted from sound and vibration signals.
|T02 SS1||Applications of active control|
This session will focus on various applications of active noise control technologies and demands from practice, which include (but are not limited to) active noise control earplugs and headsets, active noise control in mobile phones, ipads, natural ventilation windows and train compartments, active control of noise from air conditioners, PCs, oil & smoke exhaust machines, vacuum cleaners, communication chassis, large power transformers and large mining hauling trucks, and active sound barrier. Various active noise control algorithms, hardware, sensors, transducers, controllers and new trends of active noise control applications will also be covered in the session. It will provide a platform for researchers and engineers from industries around the world to exchange ideas and to find opportunity for future cooperation.
|T02 SS2||Algorithms for active control|
This session is going to continue the successful series of sessions concerning algorithms for active control organized during congresses in Stockholm, St. Petersburg, Lisbon, Vienna, Cairns, Daejeon, Krakow, Cairo, Rio de Janeiro, Vilnius, Beijing, Bangkok, Florence, Athens, and London. Active control has been still attracting attention of many researchers over the world. Although the general idea of active control is well known there is a growing interest in employing modern signal processing and control approaches, as well as sensors and actuators. Therefore, papers presenting digital or analogue control, linear or non-linear techniques, fixed or adaptive algorithms, design or analysis methods, optimisation techniques, and modern technology are mostly welcome. This session will also gain a lot if technical papers concerning applications and experimental work on active control of sound and vibration are included. It will give a chance for the researchers to meet authors of significant publications, exchange ideas and initiate cooperation.
|T02 SS3||Passive and Semi-active control of noise and vibration|
The focus of this technical session will be on passive and semi-active control of noise and vibration. Conference papers may be theoretical or experimental, and either fundamental or highly applied. Research on experimental and analytical studies of passive and semi active systems are welcome. This technical session includes general discussion and ideas for passive and semi-active control, algorithms design and analysis, mathematical and empirical modeling, practical systems and their implementation, and acoustic and signal processing aspects. Vibration and noise research studies on vibration isolators, meta structures, energy harvesters, smart materials and devices used semi-actively, and controllable fluids (ER-fluids, MR-fluids, MR-gels and elastomers) and devices are welcomed.
|T02 SS4||Sound field control and 3D audio|
Sound field control involves the selective enhancement and attenuation of different acoustic components in both the spectral and the spatial domains. There has recently been significant progress in using active techniques to improve sound quality, for example, using both active reduction of some spectral components in a sound field and active enhancements of others, to achieve a more balanced sound field. Sound reproduction techniques are also rapidly expanding into applications where it is not only required to reproduce a given sound field in one region of space, but also to ensure that this sound is not reproduced in another region of space, as in personal audio and zonal reproduction systems. Such sound field control systems require a combination of physical and psychoacoustic design, which are two of the main subjects this session.
The structured session on Aeroacoustics includes papers related to sound generated aerodynamically in aircraft, cars, high speed trains, industrial fans and compressors, and wind turbines, etc. In addition to the generation, propagation and radiation of sound, the reduction and the control of sound and flow-body interaction phenomena are included. Papers on computational aeroacoustics such as high resolution scheme development, application of schemes, and simulation of aeroacoustics phenomena are welcome.
|T03 SS2||Acoustic simulation, test and control in spacecraft|
The understanding of vibro-acoustics, the study of acoustic disturbances and the resulting structural vibration, is very critical in the aerospace industry. The high intensity acoustic fields produced during a launch of a Space Shuttle or an Expendable Launch Vehicle (ELV) can easily damage a spacecraft's mission critical flight hardware, such as its avionics, antennas, solar panels and optical instruments. Therefore, test in ground and its specification becomes a critical issue to ensure their reliabilities and functions in the flight. On the other hand, numerical analysis methods become more and more important than before as an effective tool to achieve optimization design for them and predict their performance accurately. Furthermore, structural dynamic control such as acoustic transmissivity control for firing and vibro-acoustic control for satellites or solar panels can reduce surface acoustic load for payloads and release their stress concentration and extend fatigue life. In this session, papers in acoustic measurement methods, specifications and international standards, numerical analysis models and optimization methods such as FEM, BEM, SEA and a hybrid FEM/SEA ,FEM/BEM, particle swarm optimization method, a variety of control method including passive and active are all welcome.
|T03 SS3||Aeroacoustics of fluid-structure interactions|
Sound generation by fluid-structure interactions is a major cause for aerodynamic noise at various environments, including man-made air vehicles, turbomachines, cavity and pipe flows, etc. Its physical characterization and control, normally involving acoustic-analogy-based analyses, is therefore a topic of ongoing research. The session welcomes all contributions on these and related topics, including analytical, numerical and experimental investigations, in the wide spectrum of existing problems.
|T04 SS1||Sound, noise and vibration in urban environments|
Urban environment is characterised by high human population density and many built environment features. This session aims to provide a discussion platform for noise, sound and vibration in cities. We welcome papers on urban planning, monitoring and measurement techniques, prediction methods for urban sound and vibration propagation, noise mapping software and applications, urban soundscape and quiet areas, ground borne noise and vibration, construction noise and vibration, and noise control in the urban environments etc.
|T04 SS2||Auditory situation awareness|
As described in Wikipedia, situational awareness or situation awareness (SA) is the perception of environmental elements and events, the comprehension of their meaning, and the projection of their status and consequences. It is also a field of study concerned with understanding of the environment critical to decision-makers in complex, dynamic areas from aviation, air traffic control, ship navigation, power plant operations, military command and control, and emergency services such as fire fighting and policing; to more ordinary but nevertheless complex tasks such as driving an automobile or riding a bicycle.
|T05 SS1||Flow duct acoustics and mufflers|
Papers on experimental or theoretical techniques for modelling sound generation, sound propagation and sound radiation in flow ducts will be presented in this session. Of special interest are experimental and theoretical techniques for: characterizing in-duct sound sources, propagation of sound in duct systems with flow and sound radiation from duct openings. Modelling of mufflers and noise reduction techniques for ducted systems and particularly relevant for this session.
|T05 SS2||Nonlinear acoustics and vibrations|
Nonlinear acoustics and vibration has become increasingly important during the last forty years due to the exponential increase of computation power and increasingly higher sensitivity of electronic instrumentation, and suitable signal processing. It is a broad field, which encompasses large amplitude sound waves and vibration. The nonlinearity of materials results in nonlinear effects, which arise from defects in the materials present at all scales. Applications include nonlinear nondestructive testing (NDT), harmonic medical ultrasound imaging, high intensity focused ultrasound for noninvasive surgery, cavitation, and control of high intensity jet noise and development of new materials such as nanocomposite and memory based materials. Also included are the phenomenon of chaos, which has become popular during the last twenty years with the establishment of institutes of nonlinear science and complex systems in universities and research centers. In addition, journals are now dedicated to this subject. Chaos theory is used today even in the prediction of price movement on stock markets. Structured sessions on nonlinear acoustics and vibration are present since ICSV5 in Adelaide, Australia in 1997. We have witnessed the growth in this field demonstrated by the increasing number of papers to the current number of twenty to thirty papers presented at each ICSV congress.
|T05 SS3||Sound propagation in curvilinear spacetime|
Acoustical cloaking is the first application of sound propagation in curvilinear spacetime. So far application of curvilinear coordinates in acoustics are to description of the geometric structure of stationary objects. The discovery of gravitational wave in 2014 confirmed Einstein's theory of general relativity (GR). So far applications of GR have been to large objects such as black holes and the origin of the universe. So it is time to extend GR to small scales phenomena. This is supported by towards the end of Einstein's original paper he mentioned elastodynamics and hydrodynamics as two areas that GR should be applied to. The curvilinear spacetime approach is a more accurate approach to nonlinear acoustics involving nonlinear phenomena and finite amplitude waves. This is a deductive approach with Hooke's law as a special case. This special session will introduce Einstein's field equations to acoustics. The scope of this session will include
|T05 SS4||Thermoacoustics and combustion noise|
Unsteady combustion generates sound. A particularly violent form of combustion noise tends to arise if the combustion takes place in an acoustic resonator, because then the heat release rate and the sound field can interact in such a way that they amplify one another, generating a "thermo-acoustic instability". This can lead to structural damage in gas turbine combustors and some types of aircraft, so avoiding thermo-acoustic instabilities is paramount. They are a complicated phenomenon, involving sound waves, combustion, aerodynamic effects and structural waves, as well as the interaction between all these. The aim of this session is to bring together scientists with an academic and/or industrial background in this area. Suggested topics of the current session include, but are not limited to the following: Modelling of the thermo-acoustic feedback with analytical and numerical methods; Nonlinear effects; Active control of combustion noise and thermo-acoustics; Modelling of the acoustic source processes with a view to application in analytical and numerical methods; Sound propagation in combustors with non-uniform properties; Boundary condition modelling and measurements; Physical processes involved in the generation of combustion noise.
|T05 SS5||Wave propagation application in fluids, complex solids and structures|
Acoustic wave propagation in complex solids and structures have a broad variety of applications, including source localization and characterization, structural health monitoring, ultrasonic non-destructive testing, acoustic/seismic petroleum exploration and well logging, acoustic reservoir characterizations, and so on. This structured session will provide a forum for researchers and professionals from many countries to present and discuss their latest research, applications, and ideas in all areas related to elastic wave propagation and applications. We aim to strengthen links between industry, research laboratories, and universities promoting multidisciplinary research and to cover theoretical, numerical and experimental aspects of studies of wave motion in complex solids and structures.
|T05 SS6||Pipe Vibration|
Pipework is used in many engineering applications for conveying gases and fluids over long distances at a wide range of temperatures and pressures. Vibration in pipes sometimes causes excessive noise radiation and may result in failure due to fatigue, possibly resulting in economic and environmental disasters. That some wavetypes may propagate long distances in pipes may, however, also be exploited to good effect, as in both leak detection and some vibrational pipe location methods. This structured session will cover the latest research in wave propagation modelling and measurement in pipes, undertaken in both universities and industry worldwide.
|T05 SS7||Wave propagation and control in periodic structures|
Many engineering structures can be treated as periodic, such as multi-story buildings, multi-span bridges, multi-blade turbines, stiffened plates and shells in aerospace and ship structures. In the design of these structures, vibration and/or noise levels must be taken into account. Wave propagation in periodic structure can exhibit a frequency-banded feature, which is of great interest in terms of vibration and noise control. Recently, the concept of periodic structures has been expanded due to the introduction of phononic crystals and acoustic metamaterials. This provides new novel ways for the manipulation and control of waves in periodic structures. This structured session is intended to cover both theoretical and experimental studies in these areas including:
|T06 SS1||Noise and vibration in the workplace|

|T08 SS1||Acoustic Metamaterials and Phononic Crystals: fundamentals and applications|
Acoustics is a classic field of inquiry that has enjoyed a strong revival during the past two decades, propelled mainly by the advent of phononic crystals and acoustic metamaterials, two newly developed research areas that focused on man-made structures with acoustic properties not commonly found in nature. Whereas phononic crystals denote periodic structures exhibiting frequency bandgaps in which there can be no propagating acoustic/elastic waves, acoustic metamaterials acquire their exotic characteristics as collective manifestations of local resonators. Both phononic crystals and acoustic metamateials are composite structures comprising materials of different mass densities and hardness. In the case of acoustic metamaterials, however, the response of the composite to external excitations can differ from a rigid solid by having internal relative motions between the different material components. The past fifteen years have witnessed the novel capabilities that can arise from such locally resonant sonic materials, which are characterized not only by their subwavelength physical size, but also by their effective mass density and bulk modulus that can exhibit negative values. There are tremendous scope in the applications of acoustic metamaterials and phononic crystals, such as acoustic superlens , acoustic cloaking, aeroacoustic cloaks. The recent discovery of metamaterial as artificial phase transition manifested in quantum metamaterial producing artificial superconductivity and metamaterial as route to high temperature superconductivity. Permmitivity, permeability, effective bulk modulus and effective mass density are transport properties.Metamaterials with singularity behaviour of transport properties at point of local resonance similar to that of singularity at critical point of phase transition. Based on transport properties, one can go beyond acoustic and electromagnetic metamaterials to other forms of metamaterials.With metamaterials as artificial phase transition, one can control the degree of phase transition. The unusual phenomena exhibited by the phononic crystals and acoustic metamaterials, as well as their underlying physics, are the subjects of this structured session.
|T08 SS2||Acoustic materials|

The papers analyzing the evaluation of the environmental performance of the acoustical materials are welcome too.
|T09 SS1||Psychoacoustics and product sound quality|

|T10 SS5||Low noise pavements, tires, joints, road markings, and bridges|
The development of low noise pavements and tires evolves steadily. New materials and better models lead to a significant reduction of annoyance from road traffic systems. However, more and more attention have to be paid to local discontinuities in the road surface like joints, road markings, and bridges because they become more salient if rolling noise diminishes. This requires low noise discontinuities that relate to the adjacent low noise pavements. Also, legal aspects and annoyance analyses have to be taken into account, especially when complaints of inhabitants are involved. The complexity of the topic requires an integral acoustic and civil engineering approach of the complete road system. This section welcomes contributions on fundamental modelling, measurements, legal aspects of low noise pavements and tires, and various discontinuities.

|T11 SS2||Structureborne and impact sound in buildings|
This session considers methods of measuring and predicting structure-borne and impact sound in buildings. Structure-borne sound is due to services systems and domestic appliances: heating and ventilation systems, water systems, etc. Impact sound is due to footfall on solid floors, floating floors and stair systems, and also due to transients: switches, door slams, dropped objects, etc. As well as progress in the prediction of sound resulting from impact and vibration sources in heavyweight homogeneous building structures, there also has been progress for the case of lightweight non-homogeneous constructions.

|T13 SS1||Ship and harbour noise and vibration|
Noise and vibrations generated by ships affect a wide range of receivers: crew and passengers inside the vessel, inhabitants of the coastal areas and marine fauna outside it. Recent studies suggest that a large percentage of people living in urban areas close to harbours and a number of marine species, at different evolutionary levels (in particular mammals and cephalopods), suffer from ship N&V emissions in air and in water. The present degree of knowledge of the phenomena involved in the noise emissions inside and outside ships is quite different, as a result also of the time elapsed since the negative effects were realized and therefore studied. The development of the normative framework in the various areas reflects these differences, but there are expectations for improvements on all fronts and need to be supported by the scientific community, that will definitely find in this structured session a suitable occasion for presenting the latest research results in this particular field of acoustics.
|T13 SS2||Ship underwater noise measurements, monitoring and control|
