This limitation poses significant challenges for compact and efficient low-frequency noise control. To address this issue, the present study introduces a novel sound absorption mechanism based on a two-hollow magnet quasi-zero stiffness (QZS) structure. By introducing magnetic negative stiffness, the system's effective stiffness is significantly reduced, enabling wider bandwidth at lower frequencies, thus surpassing the sound absorption performance limits of conventional Helmholtz resonators. The research integrates theoretical modeling, finite element simulation, and experimental validation using an impedance tube to thoroughly investigate the underlying absorption mechanisms. The QZS resonator allows the resonator's effective cavity height Heff to exceed the upper limit of optimal performance seen in traditional resonators, achieving up to 1.6 times the physical length, without expanding the structural volume. The results of this study offer valuable theoretical and practical insights for designing compact, high-performance QZS-based sound absorbers, with potential applications in areas like aero-engine acoustic liners and underwater noise reduction systems.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2478-2494"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145137832","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}

Most theoretical and applied studies rely solely on bearing information, and various filtering algorithms, especially particle filter methods, have demonstrated strong performance in this context. To improve upon existing approaches, bearing information is combined with received underwater sound pressure levels. This method requires no additional sensors compared to bearings-only trackings, as hydrophones-already used for beamforming-can also measure sound pressure levels. Additionally, underwater transmission losses can be estimated through simulations based on commonly available environmental data. The effectiveness of the proposed method is demonstrated using simulated data, showing improved performance-especially in scenarios without observer maneuvers. To increase realism, the impact of replacing bearing measurements with conical angle measurements is also investigated. These measurements account for both elevation and bearing angles, thereby providing a fairly comprehensive characterization of bottom-bounce paths commonly encountered under real-world conditions. This enables exploration of scenarios with different immersion levels for both target and observer. The results further emphasize the benefits of incorporating sound pressure levels measurements into the tracking process.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2590-2601"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145137893","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 advances in hearables have enabled the longitudinal monitoring of speech production and its changes. Hearables can record speech from in-ear microphones (IEMs) and outer-ear microphones (OEMs), but it remains unclear how these measurements from hearables compare to the laboratory gold standard, a microphone placed in front of the mouth. This study examines voice quality and F0 measurements across the IEM, OEM, and the standard method (REF) using parallel recordings. Results showed that the IEM introduced more variability overall; increases in jitter, harmonic-to-noise ratio (HNR), F0 maximum, and standard deviation and decreases in F0 minimum were seen for females. Decreased shimmer and increased HNR were seen in the OEM. The causes of these differences were discussed. The findings indicate that the hearable-based measurements may not align with REF standards, suggesting the need for new standards specific to hearables. Preliminary observations of sex-based differences require further investigation with adequately powered and balanced samples to determine their significance and generalizability. Future research should further explore factors such as occlusion effect and sex-specific differences (e.g., F0 range) in the relationship between hearables and REF measurements.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2238-2249"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145113727","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}

One challenge raised by this technology is to understand how humans respond to UAS sound, the characteristics of which can be varied and unfamiliar, compared with conventional vehicles. Efforts are under way to facilitate flight path planning and optimisation incorporating noise annoyance prediction models. Coupled with UAS sound emission and propagation models, perception and response could be predicted using acoustic and psychoacoustic metrics found to be associated with subjective evaluation. However, identifying the most effective metrics and models is complicated by the wide array of possible descriptors. In this study, a multi-stage modelling approach was developed. This combined a flexible, non-parametric machine learning technique to identify acoustic and psychoacoustic metrics associated with noise annoyance responses to UAS sound, obtained experimentally within immersive audio scenes. This information was used to develop semi-parametric models to predict responses while addressing cluster-correlation in the data. This technique is contrasted with an alternative multilevel, mixed-effects regression approach to highlight the potential advantages. The prediction models also demonstrate how sound intensity, ambient acoustic environments, sound qualities, and number of flights affect UAS noise annoyance.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2062-2082"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145040552","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 system relies on a physical key determined by the configuration of a tunable sonic crystal (SC) and utilizes the one-channel time-reversal (TR) technique to spatially encode each byte of the message at one of 256 possible pulse reconstruction sites. The physical encoding-decoding system consists of a rectangular array of 100 asymmetrical columns that can be controlled to rotate around its axis (SC), placed between a sound source and a grid of recording sites. During the message encoding phase, each byte is encoded as the temporally reversed impulse response recorded at a specific grid location, using a particular orientation of the columns of the SC. During the decoding phase, the signal is transmitted through the same system. Only when the configuration of the SC is the same as the one used to encode the message, each reversed impulse response generates a TR focusing peak at the site corresponding to the encoded byte, and the original message can be reconstructed with almost 100% accuracy using transmission rates up to 2.7 kilo bits/s.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2100-2110"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145064879","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 deal with random returns from inhomogeneous seabed sediment, multi-task Gaussian process (GP) regression is utilized to quantify the return variability, which is then input into a Bayesian inversion scheme to inform the data covariance and ultimately update the prior distributions of geoacoustic parameters. Experimental data were collected during the Seabed Characterization Experiment at the New England Mud Patch. This method provides range-dependent geoacoustic parameter estimates in the experiment area with a resolution on the order of ten meters. Numerical studies indicate that, for timing data with low variance, arrival times can be used to accurately estimate seabed properties. However, the performance of the inversion model deteriorates as the variance of the seabed reflection travel time data increases. The experimental data exhibit a high level of variance in the sub-bottom timing returns, likely due to the presence of inhomogeneities in the sediment layer and roughness between sediment layers. The mean and variance of the direct path, bottom, and sub-bottom arrival time measurements were calculated using multi-task GP regression. Furthermore, the results show that layer thickness and sound speeds are highly coupled. Additional prior information is required to decouple the ambiguity and uniquely determine seabed properties.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2602-2614"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145149454","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}

Limited research, mainly on head-prominence languages, shows that prominence-induced strengthening interacts with focus structure, increasing gradually across focus types. However, it is unclear how focus structure is encoded in edge-prominence systems. Here, we examine Seoul Korean, an edge-prominence language, in which the focused word is known to start an accentual phrase (AP) and exhibits prominence-induced strengthening, while the post-focal items are dephrased. Analyses of kinematic duration, displacement, and velocity, examine degree of strengthening on focused AP-initial gestures and/or dephrasing on initial gestures in the first post-focal word. Results show that focused AP-initial strengthening reflects focus structure, although kinematic dimensions differ in the number of focus types they distinguish. Yet, the order of encoded types remains consistent and similar to that found in head-prominence languages. Post-focally, there is durational evidence of dephrasing only after contrastive focus and its reach is constrained by the number of intervening syllables. Instead, the other focus types exert strengthening on the onset of the post-focal word, suggesting focus-induced spillover effects that cross-word boundaries. These findings support the view that prominence is organized as a hierarchical structure, with its levels reflecting different focus types.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2523-2536"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145149479","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 SPPAL utilizes a single Langevin-type ultrasonic transducer coupled with a flexural stepped plate to generate narrow-beam audible sound via nonlinear acoustic interaction. To evaluate and optimize the performance of the SPPAL, an integrated modeling framework is developed, consisting of an approximate analytical three-dimensional model for transducer dynamics, an equivalence ratio formulation to relate stepped plate and rigid piston behavior, and a spherical wave expansion method for nonlinear sound field simulation. The dual-resonance behavior of the transducer is optimized through multi-objective analysis to enhance low-frequency audio performance. Experimental validation includes frequency response and modal analysis of the transducer, as well as sound field measurements. The analytical methods are further verified through comparison with experimental data. Furthermore, combination resonance-an unintended structural excitation resulting from intermodulation-is identified as an inherent phenomenon in SPPAL operation.

The beam-time response of bistatic reverberation reveals interference stripes that follow distinct patterns, potentially misleading target detection and necessitating a thorough analysis of their underlying mechanism. These interference stripes are generated by mode coupling between propagating modes along both the incident and scattering paths. While mode coupling has been extensively studied for propagation, reverberation involves a complex two-way propagation process that cannot be effectively analyzed using a one-way propagation model. Therefore, this paper introduces a two-dimensional (2-D) cross term analysis. The \"2-D\" refers to the coupling not only within the incident and scattering paths but also between the incident and scattering modes. An analytical formula is derived to predict the positions of bright stripes, enabling the investigation of how the sound speed profile and bathymetry affect the interference structure. The proposed 2-D cross term analysis is validated using bistatic reverberation data collected over the continental shelf, showing that variations in interference stripes align well with predictions from the 2-D cross term theory.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 2","pages":"1077-1090"},"PeriodicalIF":2.3,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144855672","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}
