Acoustic metamaterials are engineered structures designed in such a way to exhibit acoustic properties not readily available in nature. One of the main issues of such artificial structures is the limited bandwidth over which the acoustic properties can be tweaked out. To overcome this, active control techniques have been identified as an enabler, driving a significant part of the scientific community towards the development of active metamaterials. This structured session aims at providing a snapshot of the research on active metamaterials and metasurfaces, through the presentation of theoretical and experimental investigations, highlighting the practical applications of such concepts.

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 "thermoacoustic instability". This can lead to structural damage in gas turbine combustors and some types of aircraft, so avoiding thermoacoustic 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. This session aims to bring together scientists with an academic and/or industrial background in this area. With its focus on fundamental aspects of thermoacoustics, it complements the session T03 SS07 "Dynamics and acoustics in sprays, liquid fuel flames and aero engine combustors", which focuses on the engine applications and which is organized by Jim Kok.
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.

Aircraft noise has received growing attention recently due to the ongoing expansion of the aviation sector and the ever-more stringent regulations on noise emissions worldwide. Airframe noise is significant during the approach in which the main noise sources include the airfoils and high-lift devices. Airfoil self-noise is also the main source of aerodynamic noise for many industrial fluid types of machinery, and the aerodynamic noise from the airfoils of wind turbines, unmanned aerial vehicles, and ventilation/cooling fans presents further challenges. The development of noise-reduction technologies requires an in-depth understanding of the noise generation mechanisms.
This Structured Session calls for quality original research works and/or innovative design concepts, and aims to showcase the latest developments in theoretical, numerical, and experimental investigations of the source mechanisms and control methods for airfoil/high-lift device noise. The topics of the Structured Session cover the latest advances in all aspects of the generation and reduction of airfoil/high-lift device noise in order to advance knowledge in understanding the source mechanisms and developing novel control techniques of airframe noise, as well as applying these noise suppression technologies in other scenarios and industries.

Thermoacoustic instabilities pose great threat to combustion systems as they are large amplitude pressure oscillations which can cause structural damage. Often, these instabilities are mitigated through passive acoustic dampers like acoustic liners, Helmholtz resonators or quarter- and half- wave resonators. This structured session invites papers on passive control of thermoacoustic instabilities; and is not limited to just the use of acoustic liners and resonators. It could also be design modifications, utilisation of existing phenomena like heat exchanging etc, to name a few. We invite theoretical, numerical and experimental studies (including validation studies) that effectively dampen instabilities in combustion systems.

Combustion of hydrogen from renewable sources is an emerging technology that can replace fossil fuels and so provide carbon-neutral energy. POLKA is a Marie Skłodowska-Curie Research Network running from February 2019 to July 2023; it includes with 15 young researchers working towards a PhD. Their goal is to solve serious technical problems, which are unique to hydrogen combustion: thermoacoustic instabilities and flashback. Thermoacoustic instabilities are large-amplitude pressure oscillations caused by an escalating interaction between the flame and acoustic waves; they tend to occur unexpectedly and cause major hardware damage. Flashback is the dangerous phenomenon of the flame propagating backwards into components not designed for high temperatures. New physical insight is being created by POLKA with a combination of experiments, numerical simulations and analytical techniques. This structured session will showcase POLKA's research activities in presentations by the young researchers.

Nonlinear acoustics and vibration has become increasingly important during the last forty years due to the exponential increase of computation power, 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 centres. In addition, journals are now dedicated to this subject. Chaos theory is used today even in the prediction of price movement on stock markets. Also an important topic for this session will be the application of gauge invariance approach to nonlinear acoustics and vibration which will include treatment of inverse scattering and multiple scattering problems and interactions. 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.

Acoustic cloaking is the first application of sound propagation in curvilinear spacetime. Curvilinear spacetime approach is especially suitable for intense sound and nonlinear acoustics due to the curvilinear path of intense sound field. By developing nonlinear acoustics on the curvilinear spacetime, one will increase the sensitivities, accuracies and completeness of the subject.
Also curvilinear spacetime will enable the covariance of all equations in physics. This is also a revolutionization/reformulation of nonlinear fluid mechanics and nonlinear fluid dynamics, especially for application to naval architecture and to study of jet noise, rocket noise and space shuttle noise. This structured session will introduce Einstein's field equations to acoustics. The scope of this session will include:
(1) nonlinear acoustics on curvilinear spacetime to include gravitational field
(2) derivation of acoustic field equations on curvilinear spacetime, for applications to both fluids and elastic solids.
(3) application of gauge invariance to multiple scattering and interactions on curvilinear spacetime
(3) hypersonics and astro-acoustics
(4) sonic fusion
(5) the extension of acoustic radiation force (ARF), an intense sound to curvilinear spacetime which will bring in the gravitational field. This will include topics of drug delivery and force of levitation

Whatever their size, workshops often have noise problems. More to the point smaller entities seldom enjoy a private internal health and safety service, or environmental control for that matter, and solely rely on the labour ministry doctor – if available and willing to dabble in environmental matters. The following aspects are especially tackled in this session: i) Noise in the environment (overview of regulations, consequences on operations, monitoring the noise, noise reduction problems); ii) Noise at the workstations outdoors (assessing noise exposure, reducing noise at the source, planning the work to reduce the noise exposure, case of maintenance people); iii) Considerations with regards to the industrial building (overview of regulations, requirements for acoustic absorption, reducing the sound propagation, ensuring alarm signals can be safely heard, while making sure the neighbourhood is suitably protected); iv) Legal considerations: While one may emit recommendations and hope for the best, most of the time it is necessary to implement regulations in order to achieve a result. But is it sufficient to edit a regulation if nobody is in charge of applying it? Furthermore, even in the European Union where the rules are supposed to be identical in each member country, is the law applied in the same spirit everywhere? This session aims to compare experience gained in various countries and over a broad range of subjects, and wonder about the potential perspectives.

Modal analysis is the process of determining the inherent dynamic characteristics of a system in forms of natural frequencies, damping factors, and mode shapes and using them to formulate a mathematical model for its dynamic behavior. The mathematics involved is wide-ranging, partly because modal analysis involves both time domain and frequency domain analysis. It deals with discretized dynamic systems and continuous structures. Theoretical and experimental aspects and case studies are particularly expected.

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.
This special session will cover the following topics:
phononic crystals ; nonlinear phononic crystals ; band-gap metamaterial; negative refraction; double negative metamaterial; acoustic cloaking; aeroacoustic cloak; acoustic diodes; acoustic waveguides and resonators based on metamaterial; application of phononic device to communication; sound insulation panel using metamaterial; vibration reduction using metamaterial; acoustic metamaterial as artificial phase transition.

Researchers have been trying to understand cochlear function for hundreds of years. The most serious work began with Hermann von Helmholtz (1854), who compared the cochlea to a harp (an under-water array of resonators). In 1924 Wegel and Lane did break-through modeling research in terms of a cochlear traveling wave.In 1961 von Bekesy was awarded the Nobel prize for his work on verifying the existence of the basilar membrane (BM) traveling wave.In 1970 Rhode was the first to resolve a raging controversy by showing that the traveling wave was nonlinear.But a significant break through was the 1973 discovery by David Kemp of nonlinear cochlear distortion product otoacoustic emissions (DPOAE). Years of exploration of DPOAEs resulted a significantly improved understanding the inner workings of the cochlea.The outer hair cells are the source of the nonlinear compressive motion of the basilar membrane, or cochlear-amplifier (CA), and the mapping of the BM traveling wave. The analysis by DPOAEs have proven to be the key to our present understanding of cochlear function. In the last decade Optical Cochlear Tomography (OCT) has begun to explore the inner workings of the Organ of Corti. This session covers current research regarding our understanding of how the cochlear works. At this aim it gathers the most prominent scientists in this field. Basic research is devoted to the measurements and modeling of the cochlear function. Some issues still under debate are deeply discussed such as the relation between the neural tuning curves and the suppression curves on the BM. The most promising applications are also presented ranging from the association between DPOAE and hearing threshold, the relation between the DPOAE phase and the intracranial pressure, an early diagnostic tool based on OAEs for the age related hearing loss.

Structure-borne and impact noise is invariably more complex than airborne noise in terms of measurement, prediction and determination of transmission paths. Structure-borne noise in buildings is traditionally concerned with everyday impacts from human activities such as footfall; furniture movement; object or weight drops; or high-intensity activities in fitness centers or the transmission of ground-borne vibration into the building structure. There is debate over the accuracy and practicality of structure-borne noise prediction methods, particularly when flanking structures and resilient materials are incorporated. Equally the usefulness of established single-figure rating metrics and their associated test methodology is under study with regards to human perception considering the wide range of impact sources and building partition types through which this structure-borne noise transmits. Reducing impact noise in residential buildings requires the adoption or development of materials and solutions for the control of direct and flanking structure-borne sound. Papers are sought for this technical session that address these issues related to structure-borne and impact noise, their transmission paths and prediction methods in buildings.

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 harbors and a number of marine species, at different evolutionary levels (in particular mammals and cephalopods), suffer from ship N&V emissions in the 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 reflect 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.

The low frequency underwater acoustic landscape is rich with many different sounds including the general ambient background noise. In addition there is sound from natural events, such a underwater volcanic eruptions and storm events. Many marine mammals also vocalise in the frequency range of interest here, ie below 200 Hz. Due to the low absorption at very low frequencies sounds can often be heard and recorded from hundred of kilometres from their source. There are often complex propagation mechanisms as low frequency sound also travels through the sediment. In the polar regions a number of researchers have been investigating changes in the underwater acoustics due to climate change, including transient events from ice break-away. There are also a number of man-made noises such as pile driving, surveying and, increasingly, sound coupling into the ocean and seabed from offshore wind farms. This session will welcome papers on any of the above topics, including processing and classification of LF underwater acoustics. It is worth noting that there is a separate session on Ship Underwater Radiated Noise and so you may wish to submit material there if your research is on that topic.

The tones produced by musical instruments are very beautiful and very diverse. There are various types of instruments such as strings, winds, and percussion. All of them start from the player's input (string plucking/bowing, blowing, impact, etc.) and output their own unique tones through complex phenomena including the coupled vibration and the non-linearity, etc. Various attempts have been made to elucidate the sound mechanism of these instruments through experiments and numerical calculations. In this session, we will welcome research results on all musical instruments evaluating vibration and acoustic phenomena from various aspects.

Musical instrument is a device to make musical sound, such as percussion, wind, stringed, electronic and various kinds of instruments. Singing voice may be one of most sophisticated musical instrument devices. Physical modeling aims to model and synthesize with mathematical approach to physically interpret musical sound or vocal voice. Papers related to measurement, analysis, synthesis and modeling of musical sound, singing voice or any other technique to the field are welcome to the session.

Since ancient times, many masterpieces of musical instruments which have excellent tones have been produced by artisans' experience and intuition. In recent years, on the other hand, scientific approaches have been used to propose shapes for musical instruments that produce rich tones. In addition to shape, there has also been a great deal of research seeking new materials for musical instruments, including materials other than wood and chemical treatments on wood. In this session, we will welcome research results from various fields such as design and production methods in the process of creating musical instruments.

Psychoacoustics, known as the psychology of sound, involves the scientific study of sound perception. Perception of sound or music is a process in daily life situation and environment. A simple sound can be a function of frequency, amplitude and phase, while music has its distinct element of pitch, intensity, timber and rhythm. Papers related to, but not limited, music psychology, perception of sound, audiology, sound localization, signal separation, auditory scene analysis and sound masking are welcome to the session.
