Summary: Although the continental slope and abyss are the largest habitats on earth, fish sounds are absent from deep waters. The presence of sexually dimorphic muscles on fish swim bladders suggests that sounds are likely used in male courtship on different levels of the continental slope. This study investigates the effects of environmental extremes on fish sound production by examining the acoustic behavior of a driven bubble. The findings indicate that bubbles in deep-water environments have reduced radiation efficiency, which likely contributes to the absence of fish sound recordings in those environments.

Summary: The biological effect of sound on microorganisms depends on the frequency of sound and the type of microorganism, with studies on brewer's yeast showing that sound can enhance growth, alcohol production, and alter metabolites. Sound treatments significantly impact growth rate and volatile metabolites, with differences observed between high- and low-frequency sounds, indicating potential modulation of industrial processes through the application of specific frequencies of audible sound during growth.

Summary: This paper deeply studies the acoustic streaming effects of Sonic Black Hole (SBH) through numerical and simulation methods. The flow characteristics of the acoustic medium in SBH excited by sound waves are analyzed, and the acoustic streaming effects and sound wave capture mechanism of SBH are discussed. The results show that for low-frequency sound waves, there is almost no interaction with the fluid medium flow, resulting in a uniform distribution of sound pressure. However, under the excitation of medium- and high-frequency sound waves, the interaction between the fluid medium flow and SBH structure leads to an uneven internal velocity distribution, resulting in sound wave deceleration and capture. By improving the SBH structure and increasing the complexity of the flow, the sound absorption and insulation ability of SBH can be further improved.

Summary: The study explores sound production in the longhorn cowfish, which possesses two pairs of sonic muscles for producing hums and clicks. The differences in ultra-structures between the extrinsic and intrinsic sonic muscles suggest that they are capable of producing different types of sounds. The cowfish is more sensitive to frequencies ranging between 100 and 400 Hz, corresponding to the sounds produced by conspecifics.

Summary: This study reports omnidirectional acoustic invisibility in air achieved by a locally resonant sonic material. By axisymmetrically placing elastic rods made of silicone rubber and lead around a cloaked object, acoustic cloaking in the low-frequency range is achieved. The optimization algorithm incorporating multiple scattering theory and gradient-based nonlinear programming confirms that the designed cloaking device suppresses the scattering cross section by almost 92% at the target frequency.

Summary: This study deployed a passive acoustic monitoring device to record the calls from the Larimichthys crocea during spawning in an aquaculture facility. The results showed that the backward transmission was greater for both types of calls by 1.85 dB on average, and a reduction in swim bladder size by 20% resulted in stronger sidelobes in the frontal direction, indicating its influence on call directivity.

Summary: Turbulence in compressible flows is crucial in various applications, such as air/fuel mixing strategies for scramjet combustors. However, controlling its production is more challenging compared to incompressible turbulence due to fluctuating thermodynamic quantities. The validity of Morkovin's hypothesis, which expresses density fluctuations as a function of velocity and local Mach number, is discussed in this study. The reformulation of turbulence production as a function of velocity only shows that planar turbulence production is largely unaffected by compressibility effects, validating a previous study on sustaining turbulence production using streamwise vortices. However, turbulence production terms aligned with the convective velocity are affected by compressibility even at low Mach numbers.

Summary: An unexplained explosive sound heard near Sapporo city, Hokkaido, Japan on April 26, 2021 was confirmed to be a sonic boom generated by a fireball through seismic data analysis. The source of the sonic boom was located about 100 km off the west coast of Hokkaido, with a velocity higher than that of a fighter plane. Despite the lack of optical observations, trajectory models suggest that the source of the sonic boom was likely a fireball.

Summary: This paper proposes a modified Sonic Black Hole (SBH) structure with micro-perforated panels embedded with multiple resonator cavities to enhance the absorption performance. The structure achieves high sound absorption under 6.0 kHz. The resonator cavity and micro-perforated panels contribute more to the sound absorption at low frequencies, while the SBH has an advantage at high frequencies. Sound absorption tests confirm that the proposed structure maintains a sound absorption coefficient of over 0.5 in the range of 0.05-6.0 kHz. The combination of micro-perforated panels and SBH structure has wide applications in muffler design.

Summary: Research on fish suspension-feeding apparatus has identified novel filtration mechanisms involving vortices. Structures inside fish mouths create 'backward-facing steps' by protruding medially into the mouth cavity. Computational fluid dynamics simulation of a simplified mouth cavity including realistic flow dynamics at the porous layer reveals the three-dimensional hydrodynamics. This new modelling approach will enable future design exploration of fish-inspired filters.

Summary: The swim bladder serves as buoyancy and is also involved in hearing and voluntary sound production. This study investigates the functions of swim bladder-associated muscles in lionfish species. The results show that lionfish can produce low-frequency hums and intermittent knocks as aposematic signals. Analysis suggests that these sounds are produced by muscles closely associated with the swim bladder, which also play a role in maneuvering and locomotion.

Summary: The concept of Acoustic Niche plasticity refers to the plasticity of acoustic resources allocation within a species. Few studies have focused on this adaptability in fish species. This study demonstrates that the three-spot damselfish modifies its sound production and daily sound production cycle when cohabiting with the orange-fin clownfish, in order to reduce acoustic competition and differentiate its acoustic niche from that of the clownfish.

Summary: Prezygotic barriers play a role in maintaining species diversity by preventing interbreeding, but hybridization has been observed in many taxa and can lead to offspring with intermediate phenotypic features. In cichlids, hybridization is considered to be important for their evolution and can generate new traits. A study on the courtship behavior in hybrid cichlids showed that sounds produced during courtship and color patterns were different from the parent species, indicating that hybridization can affect prezygotic barriers in cichlid evolution.

Summary: The study shows that the ability of woodpeckers to move their upper beak in relation to the braincase is important for tasks like feeding and singing. Contrary to previous beliefs, woodpeckers' cranial kinesis is not constrained and differs significantly from other closely related species. These findings suggest that pecking behavior significantly influences how cranial kinesis is manifested in woodpeckers.
