Special Issue on Wave phenomena in periodic, near-periodic, and locally resonant systems
Día de Entrega: 2024-12-31

The Journal of the Acoustical Society of America (JASA) and JASA Express Letters are calling for papers for a joint Special Issue on “Wave phenomena in periodic, near-periodic, and locally resonant systems”.

Periodic, near-periodic, and locally resonant vibroacoustic systems are receiving increasing research attention arising from their extraordinary capabilities to manipulate and control elastic and sound waves. Locally resonant systems, also called metamaterials, are artificially structured materials that can exhibit exotic wave phenomena due to the strong coupling of global (structural) and local (individual element) resonances. Periodic, near-periodic, and locally resonant systems can achieve exceptional sound and vibration attenuation or transmission performance by utilizing multiple wave scattering. The emergence of the new wave phenomena including subwavelength resonant scattering, focusing, cloaking, trapping, and nonlinear wave interaction has resulted in wide-ranging multidisciplinary applications of vibroacoustic wave scattering systems and metamaterials such as non-destructive defect detection, acoustic tomography, and noise and vibration control. This Special Issue presents recent advances on periodic, near-periodic, and locally resonant vibroacoustic systems, covering fundamental aspects of the theory of multiple wave scattering to experimental studies that demonstrate performance and potential applications of the systems. Scientists, engineers, and industry practitioners working in this broad field are invited to present their work in this Special Issue.

Topics of interest include (but are not limited to):

    Fundamental aspects of wave scattering in periodic, near-periodic, and locally resonant vibroacoustic systems
    Practical applications of periodic, near-periodic, and locally resonant vibroacoustic systems
    Tunable and reconfigurable systems
    Non-reciprocal wave propagation
    Nonlinear wave scattering and metamaterials
    Acoustic metasurfaces

Special Issue on Climate Change: How the Sound of the Planet Reflects the Health of the Planet
Día de Entrega: 2024-12-31

The Journal of the Acoustical Society of America (JASA) and JASA Express Letters are calling for papers for a joint Special Issue on “Climate Change: How the Sound of the Planet Reflects the Health of the Planet.”

Climate change is altering ecosystem productivity and changing how species interact with each other and with their environment. It follows that the statistical structure of auditory environments of ecosystems will also be altered on a planetwide scale. Changes in overall ambient sound levels, as well as the spectral and temporal characteristics of altered ecosystem soundscapes reflect conditions with potentially grave consequences in an acoustic ecology framework. The highly adapted/specialized acoustic communication systems of terrestrial and aquatic life forms alike may be compromised when ecosystems undergo rapid transitions and associated soundscapes will be concomitantly altered.

In this regard, there is a need for the development and application of cost-effective acoustic instrumentation scaled and designed for deployment in widely varying environmental conditions with signal processing algorithms to track and extract relevant acoustic features of the changing soundscape as our planetary system warms, oceans acidify, weather events intensify, precipitation patterns evolve, and the human enterprise is transformed. Recognizing the urgency of the climate crisis, this Special Issue invites papers investigating efforts to monitor and mitigate the environmental, economic, and social disruption threatened by an increasingly warm planet.

Topics of interest include (but are not limited to):

    Long-term studies documenting shifting soundscapes as global temperatures warm
    Investigations of ethological alterations and health of aquatic and terrestrial life forms (e.g., foraging, migratory patterns, communication) resulting from climate change
    Tracking changes in ocean temperature (e.g., ocean acoustic thermometry)
    Measurements of ocean acidification
    Monitoring changing weather patterns (including precipitation)
    Studies of environmental transformations caused by climate change
    Mapping underwater methane seeps
    Effects of green energy on the soundscape (e.g., wind turbines)
    Methods to monitor the carbon cycle and assess carbon sequestration
    Novel instrumentation and signal processing algorithms for monitoring climate change
    Modeling the acoustical effects of climate change
    Acoustic methods to mitigate climate change

Special Issue on Active and Tunable Acoustic Metamaterials
Día de Entrega: 2025-01-31

The Journal of the Acoustical Society of America (JASA) and JASA Express Letters are calling for papers for a joint Special Issue on “Active and Tunable Acoustic Metamaterials.”

Acoustic metamaterials are a class of materials with engineered microstructure that is carefully designed to generate on-demand acoustic or elastodynamic properties. While the metamaterials studied over the last 20 years have demonstrated a wide range of novel and useful physical phenomena, most designs have fundamental limitations due to the fixed and passive nature of their constituent material properties and sub-wavelength geometry. These limitations include narrowband operation, fixed material properties, and reduced range of achievable acoustic and elastodynamic properties. To address these shortcomings, recent research has employed active and tunable acoustic metamaterials (ATAM), which use elements that inject (extract) energy into (from) propagating waves in order to manipulate or to dynamically change the dynamic effective properties metamaterials. These approaches result in programmable structures with properties that can be tuned on-demand and/or are impossible in passive systems. For the purpose of this special issue, we define active metamaterials as those being controlled with external power via coupled fields to inject or extract energy into background fields, i.e., with circuits connected to piezoelectric transducers. On the other hand, the effective properties of tunable metamaterials are altered using approaches such as shape-morphing or responses to the application of electric or magnetic fields. This Special Issue invites all manuscripts exploring new active and tunable acoustic or elastodynamic metamaterials.

Topics of interest include (but are not limited to):

    Active metamaterials with broadband properties unachievable in passive structures such broadband, extreme mass/stiffness/Willis anisotropy
    Demonstrations of new types of tunability in controlling acoustic wave propagation in metamaterials such as origami-inspired approaches, electro-mechanical coupling, or mechanochemistry
    Computational methods for predicting ATAM including stability analysis for active metamaterials
    Metamaterials with tunable non-linear responses
    Demonstrations of ATAM scalable in the number of unit cells
    Demonstrations of ATAM for transformation acoustics devices
    ATAMs designed with methods inspired by control theory
    ATAMs with Willis, electromomentum, or other domain-coupled material properties
    Stable and extremely high gain/loss media

Special Issue on Sound Absorption and Diffusion: Modeling, Measurement and Application
Día de Entrega: 2025-04-30

The Journal of the Acoustical Society of America (JASA) and JASA Express Letters are calling for papers for a joint Special Issue on “Sound Absorption and Diffusion: Modeling, Measurement and Application.”

Absorption and diffusion from surfaces are the two main design tools for adjusting the acoustic conditions in a room. As such, the correct modelling and measurement of sound absorption and sound diffusion are of paramount importance in the creation of quality acoustics, which often results from an appropriate combination of absorptive and diffusive surfaces. Surface diffusion is a relatively young subject area, and there are many misconceptions surrounding its application and characterization. While there is greater understanding of the mechanisms of sound absorption, new research has reignited the long-running debate over its measurement and prediction.

This Special Issue aims at covering the latest developments in the prediction, measure, quantification, and design of absorptive and diffusing surfaces.

Topics of interest include (but are not limited to):

    Modeling of absorptive and diffusive surfaces
    Techniques for the measurement of sound diffusion (diffusion and scattering coefficients)
    Standardization: challenges and perspectives
    Techniques for the measurement of sound absorption (absorption and reflection coefficients, surface impedance)
    In situ vs. standardized characterization methods
    Low frequency phenomena
    Use of absorption/scattering coefficients in room acoustics simulations
    Design of absorptive and diffusive new and metasurfaces
