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}

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.

Using COMSOL multiphysics, we performed numerical simulations of an acoustic waveguide system comprising one to four cascaded spherical lenses, irradiated by a 1 MHz single-element flat transducer. Experimental analyses were conducted to validate the numerical model. The waveguide and subwavelength characteristics were measured by their full width and full length at half maximum, and the normalized acoustic intensity in the shadow region of each configuration. Our results demonstrate that the system can transmit subwavelength-focused beams over millimeter distances with minimal acoustic intensity loss. Notably, the focused beam remains effective even when the lenses are misaligned. This waveguide system shows promise for practical applications, such as non-destructive testing (NDT), where its ability to propagate highly focused waves with minimal loss improves defect detection in complex materials. Its scalability and robustness against misalignment also make it ideal for portable or fiber-based acoustic imaging devices. These features broaden its utility in minimally invasive biomedical imaging, where precision and adaptability are critical.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4031-4039"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199482","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 order to solve this problem, a reverberation suppression method for moving sonar platform based on tensor decomposition is proposed. In this method, the multi-frame data received on a moving sonar platform containing both target echoes and background reverberation is modeled as the superposition of spatiotemporal continuous reverberation, random reverberation and sparse target in the form of a tensor. A cost function is formed in which anisotropic three-dimensional (range, bearing, time) total variation and non-convex rank approximation constrain continuous reverberation, the Frobenius norm constrains random reverberation, and a tensor-weighted Lp norm constrains sparse target. The constrained optimization problem is solved using the alternating direction multiplier method (ADMM), enhanceing computational efficiency. The performance of this method is evaluated on a dataset containing a moving target and reverberation that changes rapidly in time due to the motion of the sonar platform. Experimental results show that compared with several traditional methods, the proposed method is more robust to rapidly evolving reverberation caused by the motion of the sonar platform and can retain the target energy to a greater extent.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4040-4056"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199483","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 quiet, listeners are highly adept at identifying not only a speaker's words but also the underlying emotional context. Given that distinct vocal emotions possess varying acoustic characteristics, background noise level may differentially impact speech recognition, emotion recognition, or their interaction. To investigate this question, we assessed the effects of three emotional speech styles (angry, happy, neutral) on speech intelligibility and emotion recognition across four different SNR levels. High-arousal emotional speech styles (happy and angry speech) enhanced both speech intelligibility and emotion recognition in noise. However, emotion recognition behavior was not a reliable predictor of speech recognition behavior. Instead, we found a strong correspondence between speech recognition scores and the relative power of the speech-in-noise signal in critical bands derived from the Speech Intelligibility Index. Unsupervised dimensional scaling analysis of emotion recognition patterns revealed that different noise baselines elicit different perceptual cue weighting strategies. Further dimensional scaling analysis revealed that emotion recognition patterns were best predicted by emotion-level differences in harmonic-to-noise ratio and variability around the fundamental frequency. Listeners may thus weight acoustic features differently for recognizing speech versus emotional patterns.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4085-4096"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144208840","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}

Compressive sensing can achieve high-precision airborne sound source localization with a small computational effort, but underwater target localization and ranging have not been fully achieved. This study proposes a metamaterial-based compressive sensing imaging method for underwater sound source localization and target imaging. To overcome the poor wave manipulation performance caused by the impedance difference between water and the structure, a strong coupling interaction between the flexible structure and the medium is introduced to reduce reflection and scattering, dramatically improving the acoustic signal transmission amplitude via the resonance mechanism. Analytical and numerical results show that this device can achieve directional irrelevant modulation of incident acoustic waves in different directions. Besides, the multi-information fusion compressive sensing method and dual-sensor joint compressive sensing method can reconstruct the sound source information from the received mixed signals. Experimental results show that the metamaterial-based compressive sensing imaging device realizes the perception and localization of a single sound source underwater in multiple directions. The metamaterial-based hydroacoustic imaging device eliminates the dependence on large-caliber arrays and complex control systems, thus opening the way to establish a sonar system with low cost and high precision.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4069-4084"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199487","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 procedure of ATOM corresponds to collecting the time-of-flight of early reflections in room impulse response, which is then used as the input data to reconstruct temperature within the tomographic area. Usually, the coordinates of the used transceivers are known; however, practical constraints often prevent the accurate access of these coordinates, which can have an impact on the measurement accuracy. In the present work, we address the issue of predicting accurate coordinates of transceivers. Unlike earlier published papers by Dokhanchi et al. [Measurement 164, 107934 (2020)], which are based on adjusting the distance between transceivers, we propose a robust and accurate calibration method. Results show the feasibility of the proposed method, where 109 updated coordinates out of the total 201 successfully recover a highly accurate temperature within a plexiglass box (1.33 m × 1.0 m × 1.27 m). Compared to the method based on the adjustment of the distance between the transceivers, the present calibration method reduces the uniform temperature discrepancy from 0.22 °C to 0.05 °C. Moreover, we show that this calibration method remains applicable for indoor graded temperature.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4017-4030"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199484","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, the amount of underwater small target data is scarce due to the complexity of the marine environment, which limits the performance of the learning-based supervised method. Therefore, we introduce an information theory constrained unsupervised segmentation method containing two parts: subregion division based on the information bottleneck method and potential small target region extraction based on maximum grayscale entropy. Concretely, the information channel is used to represent the division process, and subregions are determined by maximizing the gain of mutual information, which is equal to the dissimilarity measure Jensen-Shannon divergence between subregions times the size of the divided region. The binary tree data structure saves the partitioning information during the division process. Then, the region of interest is chosen with maximum grayscale entropy. Experiments show that our method is suitable for a set of active sonar echograph datasets with only pixel information. Compared with the Selective Search algorithm, the result of our method is more accurate in terms of Best Intersection over Union. In ablation studies, we try and discuss quadtree data structure instead of binary tree data structure and other similarity measures.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4119-4135"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144216138","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}

This study explores the impact of the sound radiation pattern of echolocation clicks on density estimation for two deep-diving species, sperm whales (Physeter macrocephalus) and dense-beaked whales (Mesoplodon densirostris). The likelihood of receiving a click from within the narrow half-power biosonar beam at a randomly positioned receiver is small, and the study demonstrates that the majority of clicks are likely to be detected from outside this main beam. However, the beam pattern, particularly for large angles to the animal's axis, is poorly known for most toothed whales, leading to major uncertainties in the detection probability. Using a simulated cue counting scenario with different beam pattern assumptions (n = 2 for sperm whales, n = 3 for beaked whales) combined with tag-derived movement, orientation, and sound production data, this study demonstrates that uncertainty in the beam pattern can bias density estimates from passive acoustic monitoring, especially in low-noise environments. This effect decreases in noisy environments due to reduced detection of off-axis clicks.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 6","pages":"4002-4016"},"PeriodicalIF":2.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199485","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}
