The understanding of the interaction between an acoustic wave and a complex medium is an important problem in various applications such as non-destructive testing (NDT) or biomedical ultrasound. This session will focus on experimental issues including the development of inversion procedures.

Nonlinear acoustics and vibration have 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 non-destructive testing (NDT), harmonic medical ultrasound imaging, high intensity focused ultrasound for non-invasive 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, 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. The discovery of gravitational wave in 2014 confirmed Einstein's general theory of relativity (GR) which is described on curvilinear spacetime. The Nobel physics prize 2020 further confirmed Einstein's general theory of relativity and the concept of curvilinear spacetime. So far, applications of curvilinear spacetime have been to large objects such as in astrophysics and in plasma physics. So, it is time to extend curvilinear spacetime to small scales phenomena especially to high intensity sound propagation. Curvilinear spacetime approach is especially suitable for intense sound and nonlinear acoustics due to the curvilinear path of intense sound field. So, this is the correct treatment of nonlinear acoustics. This will be useful for the design of extremely high sensitivity and high precision instruments especially to be used in space research and in tsunami detection system. This will also bring nonlinear acoustics to the next level. Also, curvilinear spacetime will enable the covariance of all equations in physics. So, it is the correct coordinates platform to be used. This is also a revolutionisation/reformulation of nonlinear fluid mechanics and nonlinear fluid dynamics, especially for applications to study of jet noise, rocket noise and space shuttle noise.

The investigations in this structured session can cover the latest development in theoretical, numerical and experimental approaches concerning control methods for aeroacoustics, involving (but not limited to) fan noise, jet noise, aircraft noise, wind tunnel noise, vortex-sound resonance and thermoacoustic instabilities. Here, thermoacoustics instabilities are not limited to just the use of acoustic liners and resonators. It could also be designing modifications, utilization 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.

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.

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 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.

The noise and its perception of an aircraft is a crucial factor in attaining community and regulatory acceptance. Thus, in the recent development of quieter, more sustainable aerial vehicles from short-to-medium-haul jetliners to urban air mobility, understanding and accurate prediction of propeller noise, as the primary element in the propulsion configurations, has become increasingly important and an integral part of the design process. In this session, we aim to include the latest research and development work on propeller noise in its broad definitions, which include analytical, numerical, and experimental investigations of the isolated propeller/rotor noise as well as in the installed configurations; moreover, works on examining the propagation and impact of the propeller noise on the community are also highly encouraged.

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 several marine species, at different evolutionary levels (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 find in this structured session a suitable occasion for presenting the latest research results in this field of acoustics.

Exposure to excessive noise levels can be more than just a nuisance, causing far-reaching consequences for both ecosystems and human well-being. In pursuing sustainable and lovable cities, addressing this challenge is increasingly higher on the agenda. However, noise is a unique environmental parameter, as its perception and impacts are very complex and surprisingly subjective. For this reason, more than for any other environmental issue, involving citizens in environmental noise monitoring is key. This thematical session explores the pivotal role of citizen science in understanding, monitoring, and mitigating environmental noise and how it can be used to grasp the multi-faceted dimensions of the acoustic environment, from the impact of road-, air- and rail traffic noise to the restorative role of natural sounds. Citizen science, an increasingly influential movement, empowers individuals to actively participate in data collection, analysis, and advocacy, providing researchers with valuable insights into the perceived and objective impact of environmental noise. This session aims to bring together an international set of researchers on environmental noise who use the power of citizen science to share insights, experiences, and innovative approaches. By emphasizing the power of grassroots initiatives, the democratization of environmental data collection and the importance of technological innovation, we seek to inspire collaborative efforts to address the urgent challenge of noise pollution and create healthier, quieter, and more harmonious living environments for all.
