We propose a physics and metadata-guided generative learning (PMGL) framework comprising physics and metadata-guided acoustic generation (PMAG), physical semantic coverage expansion (PSCE), and physical semantic distribution rebalancing (PSDR). PMAG constructs structured physical semantic conditions from metadata and environmental priors to guide text-to-audio generation. PSCE expands intraclass condition coverage for few-shot UATR, while PSDR supplements underrepresented categories to construct a more balanced training distribution for long-tailed UATR. Experiments on the ShipsEar and DeepShip datasets demonstrate consistent improvements in recognition performance over the original training setting and a baseline based on a generative adversarial network (GAN), particularly under data-scarce and distribution-imbalanced conditions. The results indicate that the proposed PMGL framework effectively compensates for structural data deficiencies in underwater acoustic recognition.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"3505-3516"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149269503","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 equivalent source method (ESM), which relies on least squares inversion, is highly susceptible to measurement outliers. To address this, we present an ESM-NAH reconstruction approach, iteratively reweighted least squares (IRLS)-total variation (TV) and ℓ1 regularization (IRLS-TV+ℓ1), which employs bounded-influence M-estimation with IRLS to mitigate the impact of outlier-contaminated measurements. In addition, the method incorporates TV and ℓ1 regularization to capture both extended and compact source features. To evaluate performance, we simulate a piecewise-constant block source on a 16 × 16 grid at 25 dB signal-to-noise ratio (SNR), with 5% of channels corrupted by outliers. The proposed method achieves a reconstruction relative error of 4.4% under outlier contamination, compared to 4.3% for uncorrupted data. By comparison, Tikhonov regularization degrades from 15.9% to 96.3% relative error, sparse Bayesian learning (SBL) from 26.1% to 195% relative error, and the fused total generalized variation (F-TGV) benchmark from 7.8% to 168% relative error. Experimental measurements further indicate degradation factors of 11.5×, 14.0×, and 15.9× for Tikhonov, SBL, and F-TGV, respectively, under 5% introduced outlier contamination, whereas IRLS-TV+ℓ1 exhibits only a 1.02× increase.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 3","pages":"2288-2300"},"PeriodicalIF":2.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148977237","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}

Near-field HRTFs generally vary with source direction, distance, frequency, and individual. This multifaceted dependence presents significant challenges in near-field HRTF measurement and calculation. This study aims to reconstruct individualized near-field HRTFs with high-directional resolution from a small set of directionally measured or calculated data at a fixed far-field distance. By using the 4th-order tensor decomposition, near-field HRTFs are decomposed into a weighted combination of direction, distance, frequency, and a small number of individual-related modes. A training dataset of near-field HRTFs is used for the decomposition to calculate universal direction-, distance-, and frequency-related modes and the weights. For new individuals excluded from this dataset, individual-related modes are estimated from a small set of directional measurements or calculations of far-field HRTFs. Subsequently, this enables the estimation of individualized near-field HRTFs with high-directional resolution. Analytical examples demonstrate that a small number (15 or 14) of individual-related modes account for over 98% of the individual-related variation in HRTF magnitude square. Furthermore, high-directional resolution near-field HRTF magnitudes can be estimated using far-field data composed of 30 or 32 directional calculations or measurements. These findings are validated through psychoacoustic experiments, confirming the efficiency of the proposed method.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 3","pages":"2015-2036"},"PeriodicalIF":2.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148887831","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}

Four concert halls were represented in controlled in virtual reality environments. A total of 43 participants (23 acousticians, 20 architects-all with experience and interest in concert hall acoustics) participated in the experiment. During the experiment, all the participants were exposed to audio and video excerpts in two different positions across the four concert halls. An individual vocabulary profiling method (IVP) was used to collect the participants' attributes and textual ratings of the virtual spaces. The data were further analyzed via hierarchical multiple factorial analysis. The results reveal significant distinctions in the perceptual vocabulary and evaluation strategies employed by the two groups of professions, quantifying the perceptual dimensions without consensus vocabulary. They reveal a quasi-bidimensional perception space on architects using visual attributes and on acousticians using auditory attributes, but a higher perception space for the inverse modalities. Finally, the correlation between subjective and objective acoustical parameters reveals discrepancies between both expert groups on which objective parameter correlates with subjective balance and timbre, while it shows agreement for other subjective parameters.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 3","pages":"1971-1984"},"PeriodicalIF":2.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148865556","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}

Acoustic vortex (AV) provides an alternative to expand the channel capacity by exploring the orbital angular momentum dimension. In this work, based on the ring-array of sectorial transducers, we propose a scheme for constructing double-ring perfect acoustic vortex (DR-PAV) beams by applying the Fourier transformation of quasi-Bessel acoustic vortex (QB-AV) beams with different radial wave numbers. The radius and ring width of the inner and outer rings of the DR-PAV beam remain nearly constant, and the topological charge (TC) of the inner and outer rings are independently controllable. Subsequently, the inner and outer rings of the DR-PAV beam are further treated as two independent channels for data transmission. At the receiver end, decoding of DR-PAV beams with multiplexed TCs is achieved by using a simplified double-ring receiver array. This multi-channel underwater data transmission scheme is expected to be applied in acoustic communication in the future.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 3","pages":"1958-1970"},"PeriodicalIF":2.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148865559","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}

Formation of deep and well-defined beampattern nulls are crucial for effective suppression of interfering sources in applications, such as hearing-aids, rotor-noise mitigation in drones and unmanned aerial vehicles, and hand-free voice communication. While performance measures, such as white-noise gain and directivity factor, assess noise robustness and global spatial selectivity, they do not explicitly quantify the depth and angular extent of these nulls. To address this, we first investigated null-related measures, namely, null-depth (ND) and null-width for different beampatterns of a first-order PDMA configuration. Second, the paper presents a study on signal quantization effects across different PDMA beampatterns by deriving an analytical expression for the quantized beampattern and ND. ND invariance with respect to steering angle is demonstrated, and its dependence on temporal frequency and inter-sensor spacing is characterized. Third, this work reports the achievement of a measured ND of -61.93 dB for a first-order planar cardioid. The experiment results provide proof-of-concept evidence for the analytical framework and demonstrate practical effectiveness of PDMA in suppressing interference. Key experimental considerations required to achieve such sharp and well-defined null are also discussed.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 3","pages":"2670-2682"},"PeriodicalIF":2.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149075033","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}

Synchronous high-speed imaging and hydrophone measurements in a water tank capture the transient bubble evolution and the acoustic signatures, clarifying the relationship between tail bubble dynamics and acoustic radiation. A boundary integral model reproduces the experimental observations, and a natural frequency model is developed to characterize the acoustic response of non-spherical bubbles. A systematic parametric study is then performed to evaluate the effects of ventilated pressure and free surface on tail bubble dynamics and acoustic radiation. The results reveal a stage-dependent acoustic radiation feature: acoustic radiation is negligible while the cylinder moves inside the launcher. Upon exit, significant acoustic radiation is produced by the tail bubble. After pinch-off, oscillations of two residual bubble structures dominate late-stage acoustic signals. The proposed model shows good predictive accuracy for the tail bubble natural frequency. Furthermore, the dominant acoustic frequency exhibits a non-monotonic depth dependence with a distinct minimum at intermediate depths. Beyond a critical depth, it is primarily governed by the ambient pressure. These findings constitute a valuable reference for underwater launch bubble acoustics.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 3","pages":"2716-2732"},"PeriodicalIF":2.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149081204","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 three-port BTM is computed using a combination of finite-element and finite-volume methods. Complex-valued matrix elements are obtained, where the imaginary part represents acoustic reactance and the real part acoustic resistance. Reactance is evaluated by solving the pressure wave equation in the frequency domain, whereas resistive effects are captured by solving the incompressible Navier-Stokes equations for a multi-component gas. Acoustic forcing is applied separately at each port using harmonic or broadband signals in the range 50-650 Hz. The resulting pressure and velocity responses at both inlets and the outlet are used to assemble the 3×3 BTM. The numerical BTM is compared with predictions from an extended l-ζ model. The effective length and pressure loss coefficient are identified by fitting the simulated matrix components to the model. However, extending the classical two-port l-ζ formulation to the present three-port configuration is found to be invalid, as indicated by non-zero coupling terms between the inlets and unrealistically large fitted parameters. Variations in operating conditions, including speed of sound and inlet momentum ratio, show only minor influence on the BTM.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 3","pages":"2704-2715"},"PeriodicalIF":2.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149081217","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}

Many existing tracking methods rely on post-processing or computationally intensive techniques, limiting their applicability to embedded devices. To overcome these limitations, we present a time-difference-of-arrival-based tracking algorithm that tracks multiple sources in the direction-of-arrival (DOA) domain. A key architectural feature of the method is the decoupling of continuous per-frame DOA estimation from source enumeration, enabling these processes to execute on parallel threads and ensuring that source enumeration does not degrade real-time throughput. We implement the algorithm in an open-source c++ software package, freewilli: Free software for Whale Identification and Localization with Low-Power Implementation. We demonstrate its effectiveness on passive acoustic recordings of diving beaked whale groups from a small volumetric four-channel hydrophone array deployment and show through a systematic parameter sweep that real-time processing latency remains stable across a wide range of detection rates and clustering configurations.
