Seismic airgun arrays are inherently directional sources, producing frequency-dependent radiation patterns that vary with azimuth and dip angle. Empirical validation of directivity effects at far-field ranges has been limited. This study combines acoustic measurements with an integrated direction- and dip-dependent source and propagation model to characterize the directivity of seismic surveys in the Gulf at ranges exceeding 700 km across 15 monitoring sites. The integrated model reproduced measured airgun pulses with errors ranging from 3.3 to 5.9 dB across 15-250 Hz, with performance varying with azimuth, frequency, and propagation complexity. Gulf-wide propagation simulations extending to 1050 km demonstrated that source orientation relative to bathymetry alone restructures the spatial footprint of seismic energy at sidelobe frequencies (>100 Hz), with north-south orientations producing higher sound levels across a broader geographic area than east-west orientations at the source locations in this analysis. These results demonstrate that source directivity and bathymetry strongly influence the basin-scale distribution of seismic acoustic energy, with implications for environmental impact assessment and acoustic exposure of marine species in the Gulf.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"3559-3571"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149269555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, in multipath propagation environments, signal distortion caused by propagation paths further complicates the separation and reconstruction of the target signal. In this study, a hybrid replica-based adaptive time reversal processing (ATRP) method is proposed to reconstruct target ship noise in environments where multiple ship noises are overlapped. First, the Green's function of the propagation path is estimated from the received signals using blind deconvolution, and a hybrid replica is constructed based on the estimated result. The generated replica is then used to perform ATRP, enabling selective reconstruction of the target ship noise. The performance of the proposed method was verified through numerical simulations, and its applicability was examined using real ocean data. The reconstruction performance of ship noise was evaluated based on spectral characteristics and sound pressure levels. The results demonstrate that the proposed hybrid replica-based ATRP method can effectively reconstruct the main spectral characteristics of target ship noise even in environments with overlapping ship noises.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"2886-2901"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phenomenon is attributed to the pressure loss at the vent hole of the reed chamber opened partially by the pallet. This pressure loss causes the internal pressure of the reed chamber to fluctuate in a way that exerts a stronger force to close the reed near its closed position and a weaker force when it is open. Consequently, the restoring force of the reed is partially offset, leading to a decrease in the effective spring constant and thus causing the pitch to bend. To elucidate this mechanism, the qualitative behavior is first explained using an equivalent circuit, followed by the presentation of a physical model of accordion sound production. Through numerical simulations and theoretical nonlinear oscillation analysis, the model, incorporating adjustable pressure loss coefficients whose calibrated values are hydrodynamically realistic, yields results in good agreement with those from the accordion pitch-bending experiment of Okada, Nishimiya, and Cho [J.

Smoothed particle hydrodynamics (SPH) provides a Lagrangian framework for such problems. However, conventional SPH accumulates numerical dispersion during long-range broadband propagation. Its kernel-gradient operator acts as a dispersive filter, producing frequency-dependent phase distortion, high-frequency attenuation, and spurious trailing oscillations. Direct assignment of broadband signals to particles may produce discontinuous pressure distributions within the source region, thereby distorting the injected waveform before propagation. This paper proposes an analytically dual-scale kernel (DSK) reconstruction operator that cancels the leading dispersion error at the operator level. Combined with the corrected smoothed particle method (CSPM), it corrects spectral dispersion and local consistency errors. A retarded-time source loading strategy with impedance matching is introduced to prevent injection-stage distortion. The framework is validated through one-dimensional long-distance propagation, two-dimensional plane wave propagation, and cylindrical-wave radiation. Results show that DSK-CSPM reduces the one-dimensional L2 pressure error by approximately a factor of 150 relative to standard SPH, brings phase velocities close to the sound speed, and incurs a computational overhead of 2.9% in the two-dimensional plane wave test. The method provides an accurate and efficient strategy for high-fidelity particle-based broadband acoustic simulation.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"3093-3106"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149194878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finite-element method analysis reveals that the slit facilitates acoustic wave entry, exciting local resonances and promoting mode conversion to enhance shear energy dissipation. The helical water cavity reduces structural stiffness, facilitating low-frequency resonance and amplifying the mode conversion effect within the rubber damping layer. Simultaneously, the stepped metal plate optimizes impedance matching and enhances frictional energy consumption at the rubber-metal interface. This plate promotes wave-mode conversion and thereby enhances viscoelastic energy dissipation in the surrounding rubber, contributing to improved high-frequency absorption performance. Structural optimization using a deep neural network and particle swarm optimization demonstrates that effective absorption is achievable at 80 Hz with a 0.5 loss factor. The average absorption coefficient reaches 0.94 across the 10 Hz to 10 kHz range.

Although SOVTE are widely used in voice therapy and pedagogy, the physiological mechanisms underlying their therapeutic benefits remain unclear. In this computational study, voice production at different vocal fold configurations with and without semi-occlusion was investigated in a three-dimensional model. Semi-occlusion significantly increased phonation threshold pressure under conditions of weak vocal fold adduction. Under conditions of strong vocal fold adduction, semi-occlusion reduced mean glottal area and increased the duration of glottal closure. These findings suggest two possible adaptation mechanisms through which SOVTE may guide speakers toward an efficient phonatory configuration. For speakers with hypofunctional voice, increased respiratory effort associated with elevated phonation threshold pressure may encourage increased vocal fold adduction. For speakers with habitually tight vocal fold adduction, increased duration of vocal fold contact may alter mechanosensory feedback and promote compensatory reductions in vocal fold adduction. Together, these adaptations may facilitate adoption of an intermediate vocal fold adduction configuration, which is associated with high vocal efficiency and reduced risk of vocal fold injury. Such adaptation effects may persist briefly after SOVTE but gradually diminish over time.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"2736-2743"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13682269/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many anurans, especially treefrogs, appear to possess similar vocal capabilities; however, the complex combinatorial nature of amphibian vocal systems has been studied less extensively. In this study, we recorded 2002 calls from 75 male spot-legged treefrogs (Polypedates megacephalus) in natural choruses and conducted playback experiments to examine their responses to different call types. We found that males can produce rich compound calls by combining three vocal units-simple A, B, and C calls, consisting of A, B, and C notes, respectively. In natural choruses, they specifically generated different combinations (e.g., AB and BA, CAB, and CBA) of these calls using the same vocal units. In playback experiments, males responded differently to simple A, B, and C calls. Furthermore, male receivers exhibited distinct calling behaviors when presented with combination calls vs separate, ordered calls composed of identical components (e.g., CA vs C + A, AB vs BA, CAB vs CBA). These results suggest that spot-legged treefrogs may communicate using diverse vocal combinations that vary in both units and orders. This study enhances our understanding of vocal complexity in non-human animals.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"3365-3373"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149245070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When measurements are collected by a single hydrophone with a moving source, the data provide limited depth diversity, so the range dependence of the field is the most directly constrained component. We derive a one-dimensional governing equation that describes the complex pressure field as a function of range, enabling physics-constrained reconstruction from single depth measurements. The reconstructed field is used for source depth estimation through synthetic aperture beamforming. By suppressing range-induced phase fluctuations and yielding a smooth, physically consistent range dependence through the range-only governing equation, the proposed PINN reduces spectral broadening and sidelobe levels in the wavenumber spectrum. Numerical simulations and SWellEx-96 experimental data show that the proposed PINN can reconstruct the field under incomplete sampling and range perturbations. The method is also robust to sound speed profile mismatch of a certain level, due to the combination of physical constraint with the data-fidelity loss term.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"3306-3320"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149245102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tire air-cavity mode is a major source of spindle forces transmitted to the suspension and can contribute to increased interior noise. Previous studies have shown that the fundamental air-cavity mode of passenger-car tires, typically near 200 Hz, splits into two distinct acoustic modes under static loading because geometric symmetry is lost. In this study, dispersion relations were measured for loaded tires, and a coupled finite element (FE) model was developed to characterize this frequency split and its relation to force transmission at the wheel hub. The frequency split was quantified as a function of static load, and the coupled simulations showed pronounced hub-force peaks when the split acoustic modes coincide in frequency and circumferential wavenumber with neighboring structural modes. The principal contribution of the present work is therefore not the general observation that cavity resonance can increase hub force, but the experimental and numerical identification of the deformation-induced frequency split and its modal-coincidence mechanism with the tire structure. An additional impedance-boundary sensitivity simulation shows that the representative absorbing boundary strongly suppresses the cavity-related force peaks, providing an additional numerical check of the modal interpretation. These results provide a physically based framework for interpreting and mitigating tire-cavity-induced structure-borne force transmission.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"3374-3385"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149269469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
