One way of studying whale species is passive acoustic monitoring (PAM). At least one type of Omura's whale vocalization has been attributed to this species by simultaneous visual and acoustic observations. Although the spectral features of Omura's whale sound have been described, the source level (SL) remains undetermined. Knowledge of the SLs of acoustic vocalizations by whales is needed to estimate detection ranges for PAM to better understand whale acoustic behavior and assess the effects of surrounding noise. In this study, the SL of Omura's whale sound was estimated from passive acoustic recordings produced with four autonomous recorders deployed in a tracking array configuration. Acoustic detections were used to localize individual whales and estimate the source sound level after correction for propagation loss. A total of 29 calls were localized, resulting in the estimated mean SL of Omura's whale sound varying from about 180 dB to nearly 190 dB re 1 μPa m.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4196-4202"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144216170","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}

These phibits are realized on a metastructure composed of aluminum rods glued with epoxy. First, we realize a single phibit gate in a general form for a Bloch sphere representation, providing a foundation for implementing arbitrary gate operations on a single phibit. Second, within a single mathematical representation, we achieve either the Hadamard or NOT gate by applying the corresponding distinct physical actions for each. Third, we demonstrate the implementation of a sequence of two quantum-like gates, Hadamard followed by CNOT, using a single physical action. This illustrates the effectiveness of the phibit framework, which has the potential to simplify the implementation of a whole series of sequential gates into a single unified physical operation. Finally, we realize a universal set of gates, including the Hadamard, CNOT, and T gates, within a single mathematical representation with three distinctive actions. This approach addresses prior limitations of phibit-based gates, such as Hadamard and CNOT, which were implemented in separate mathematical representations, by introducing a unified framework that eliminates the need for distinct formulations maintaining computational efficiency.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4437-4448"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144317213","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 current predictions for SI use ray models, which are high frequency approximations, and work only at ranges that are either very close to the source or asymptotically far away. The far ranges lie in the \"Rayleigh-regime\" of propagation. Other physics-based models use modes of the waveguide in transport equations, and yet do not yield high-order statistics, such as the SI. This paper also uses modes but models the propagation across range as a product of random propagation matrices. The matrices are unitary, and independent of each other. These types of matrix-products are used to run Monte-Carlo simulations for mode, and wavefront statistics across different ranges. To confirm the predictions, this paper compares them against complementary parabolic equation simulations. This paper also shows that the product of random matrices is equivalent to a Dyson Brownian Motion (DBM) process across range. Expressions from DBM are used to analytically predict the statistics of the signal in the asymptotic limits for propagation and also suggest approximations prior to the Rayleigh-regime.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4346-4357"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144302359","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}

To this end, the study transferred the speech rate, rhythm, and intonation (and combinations thereof) of monolingual English speakers from England to the segmental materials of bilingual native speakers of English living in Austria, and vice versa, using the prosodic transplantation paradigm. The results of an accent rating experiment in which native English listeners (n = 160) evaluated the nativeness of the manipulated productions revealed that transfer of the monolinguals' speech rate, but not intonation and rhythm, led to an increase in the perceived nativeness of the bilinguals' productions. Conversely, transfer of the bilinguals' intonation and rhythm, but not speech rate, led to a decrease in the perceived nativeness of the monolinguals' productions. Moreover, the study found that combinations of manipulated cues enhanced the effects of individual cues in isolation further and that sentence type plays a critical mediating role in nativeness ratings. Together, the findings of this study demonstrate that listeners make similar use of the three prosodic cues when judging non-nativeness in L1 attriters, as shown previously in L2 learners.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4322-4335"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144285081","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}

Recent works have indicated that high-precision measurements may call for a diffraction correction model accounting for a full set of electrical and mechanical boundary conditions at transmission, reflection, and reception, such as the finite element diffraction correction (FEDC) model. However, the FEDC model has yet to be verified experimentally. In this work, the frequency-domain diffraction correction in an ultrasonic measurement system is measured, and compared to the FEDC model and a commonly used piston-type diffraction correction. One-way and three-way propagation are studied for an example system consisting of two piezoelectric ceramic disks in air separated by 0.10 and 0.15 m, vibrating in the frequency range of their lower radial resonances (50-300 kHz). Comparisons with measurements indicate that the FEDC model generally provides improved descriptions of diffraction effects compared to piston-type models. Specifically, mean absolute errors are decreased by 0.4-4.6 dB and 37-160° when using the FEDC model in the studied example, for magnitudes and phase angles, respectively. This shows that use of the FEDC model to correct for diffraction effects may increase the accuracy of high-precision measurement systems.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4273-4284"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144248416","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}

However, attempts to enhance coupling with the flexural resonance (FR) of the radiation head have demonstrated that effective interaction between FR and LCR remains unachieved, thereby constraining the operational bandwidth of the JH transducer. This study addresses this limitation by proposing a sound field model for the JH transducer under flexural vibration and elucidates the inherent physical constraints. By exploiting the vibration characteristics of FR, two oscillating structures are introduced into the JH transducer. The effects of oscillating structures on resonant frequency and emission performance are evaluated using the finite element method. It is shown that the resonant frequency and the associated sound field can be manipulated through mass effects and the interference principles of coherent sound waves. A prototype of the proposed JH transducer is fabricated, and experimental validation supports both theoretical predictions and finite element simulations. This research achieves successful coupling among LR, LCR, and FR, significantly extending the operational bandwidth of JH transducer. These findings provide new insights into the control of resonant frequency and sound field in free-flooded transducer designs.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4136-4156"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144216137","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}

Based on the propagation of torsional waves in the structure, a GPC with lattice of concave hexagonal is proposed by introducing the gyroscope element into the concave hexagonal infinite periodic structure. The bandgap characteristics of GPC are analyzed, and the mechanisms of opening the Dirac cone and generating topological edge states due to changes in gyroscope torque are discussed. It is discovered that through the breaking of structural symmetry and time-reversal symmetry, two band gaps can be opened where two topological edge states can be found with a same topological GPC arrangement. Subsequently, the influence of gyroscope rotation velocity on the bandgap is meticulously examined, uncovering phenomena such as band inversion and the manifestation of valley Hall edge states. The investigation is extended to analyzing the supercell of the topological GPC. The wave propagation characteristics at topological interfaces in the two new band gaps with different arrangements are discussed, and the directivity difference between the topological edge states of the upper and lower band gaps is revealed.

The proposed approach synergistically combines analytical expressions for transmission and reflection coefficients at high frequencies, derived from the Johnson-Champoux-Allard model, with experimental measurements of the magnitudes of transmission coefficients at oblique incidence and Brewster angles. Notably, this method dispenses with a fixed ratio assumption between Λ' and Λ, and does not rely on computationally intensive and noise-sensitive inversion techniques nor on the use of dual-fluid saturation, which may compromise the integrity of the material's microstructure. By incorporating multiple angles of incidence, the method enables the extraction of additional information from the medium, potentially revealing anisotropic or heterogeneous features and thereby improving model accuracy. The experimental setup employs a standard ultrasonic measurement system with a signal generator, two 100 kHz transducers, and a digital oscilloscope. The results obtained for melamine and polyurethane foams, which are widely used in building acoustics and the automotive industry, exhibit overall consistency with values reported in the literature, further supporting the robustness and reliability of the proposed method.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4546-4558"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144475717","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}
