This study extends the application to incompressible flow-induced noise by introducing a low Mach number characteristic boundary condition (LMCBC) to eliminate sound wave reflections at boundaries. This boundary condition is derived from the second type of acoustic perturbation equations (APE-2) and implemented within the open-source software OpenFOAM (OpenCFD Ltd, Bracknell, Berkshire, UK). The flow field is computed using the incompressible Navier-Stokes equations, and APE-2 predicts the acoustic field. The accuracy and robustness of the coupled solver and the new boundary condition are validated through multiple benchmark problems. Plane-wave test cases are then used to compare the non-reflection performance of LMCBC, perfectly matched layers (PML), and damping layers under varying incidence angles and Mach numbers. To further improve performance, LMCBC is combined with PML to form PLMCBC, and a zonal low Mach number characteristic boundary condition (ZLMCBC) is proposed by gradually attenuating characteristic waves within a buffer zone. Both extended schemes exhibit enhanced non-reflective performance for low Mach number flows (Ma= 0-0.3), with ZLMCBC achieving the lowest reflection levels and the reduced sensitivity to wavelength variations within the tested range.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 1","pages":"529-547"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144659505","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 is accomplished by using an inverse strip theory approach and transforming the three-dimensional turbulence spectrum, which models inflow conditions, into a one-dimensional term. This latter modification enhances the low-fidelity prediction tool in two key ways. First, it enables its application in cases where turbulence modeling is unavailable, or detailed inflow characterization is impractical. In this way, for example, hot-wire anemometry measurements of the incoming turbulence can be used to compute the acoustic prediction. Second, since the conversion of the turbulence term entails introducing two new functions describing spanwise and axial turbulence correlations; this approach establishes a framework for Amiet's theory in which the contributions to turbulence alteration and noise scattering are separated and represented individually. This \"modular\" structure enables independent analysis and modeling of these contributions, facilitating the application of Amiet's model to complex flow configurations and rotor geometries. The proposed methodology is successfully validated through experimental measurements of a simplified axial-flight turbulence-interaction setup, where a two-bladed propeller interacts with grid-generated turbulence at three different advance ratios.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 1","pages":"461-475"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144642811","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 this context, this paper proposes a chirped porous material based on the Cantor fractal, and the performance of the absorber is estimated under normal and random wave incidence. For normal incidence and using the transfer matrix method with the Johnson-Champoux-Allard-Lafarge model, and through numerical simulations and experimental tests, this paper demonstrates that the proposed absorber with increasing infinite complexity maintains an average sound absorption (Qα) greater than 90% in a wide frequency range (100-6400 Hz). To achieve these results, the initial generation of the fractal structure must be composed of porous materials with different flow resistivity (σfi), i.e., σf1>σf2. Furthermore, based on the concept of radiation impedance and the first empirical London model, this paper proves that for random incidence, the absorber maintains a behavior similar to that observed for normal incidence up to the second iteration of the structure. Therefore, this study suggests that the Cantor fractal pattern allows the development of broadband sound absorbers that consider a smaller amount of porous material in their design.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 1","pages":"16-27"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144540627","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}

Feature distortion in practical environments hampers speaker discrimination, driving the quest for more robust features beyond traditional inputs. Whereas wavelet transform (WT) is typically employed in classification tasks, this research uncovers its potential in speech separation. By integrating discrete wavelet and wavelet packets during model training, the study evaluates the impact of WT on enhancing speech separation applications. Additionally, it addresses the challenge of incorporating wavelet scattering (WS), known for lacking an exact inverse transform, into speech separation tasks. To overcome this limitation, wavelet scattering coefficients are integrated into the loss function, expanding its utility. Results demonstrate the superior performance and resilience of wavelet-based models in noisy conditions. Particularly, integrating WS coefficients enhances separation accuracy, surpassing other methods in key metrics, such as scale invariant-signal to distortion ratio, mean opinion score, and short time objective intelligibility, establishing wavelet coefficients as state-of-the-art solutions for speech separation in challenging acoustic environments.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 1","pages":"201-209"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144584213","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 present experiments evaluated spectral weights for the spatial cues underlying these two tasks by filtering stimuli into 1-octave-wide bands and dispersing them on the horizontal plane. Target stimuli were 100-ms bursts of speech-shaped noise or words produced by 24 male and female talkers, and maskers (when present) were sequences of words. For localization in quiet, weights differed depending on the midpoint and band dispersion range, but they were similar for speech and noise stimuli. For bands dispersed between -15° and +15°, weights peaked at 500 and 1000 Hz. Introducing a speech masker changed the magnitude of weights for localization, but not the relative weight by frequency. For speech-in-speech recognition, sequences of masker words produced predominantly informational masking, such that participants had to rely on spatial cues to segregate the target. As for localization, recognition appeared to rely predominantly on spatial cues in the 500- and 1000-Hz bands. Trial-by-trial data suggest that correct word recognition relied on differences in perceived location of target and masker speech for some but not for all participants.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 1","pages":"186-200"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144584216","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 difficulty is further compounded by both inter- and intra-speaker variability. This study employed machine learning methods to examine the effectiveness of eight acoustic cues for tone 2 and tone 3 classification in speech that were produced by 20 speakers under normal and loud speaking modes (experiment 1). Additionally, we compared the perception between native listeners and medium-to-advanced Thai L2 learners of Mandarin, including perceptual accuracy, cue-weighting strategies, and perceptual space (experiment 2). Results of experiment 1 show that temporal cues are more effective than height-related cues for tone 2 and tone 3 classifications in speech with inter- and intra- speaker variability. In experiment 2, medium-to-advanced Thai L2 learners produced more confusions than native listeners. The ranking of perceptual acoustic cues is generally similar to native listeners, suggesting that these L2 learners have generally mastered the correct cue-weighting strategy for distinguishing between tones 2 and 3. Additional analyses showed that the confusion stems from learners' perceptual biases. Specifically, learners allocate narrower space for tone 3 category than native listeners, with atypical tone 3 exemplars being misidentified as tone 2.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 1","pages":"391-406"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144637410","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 limitation, however, is the inability to reliably distinguish calls produced by the tagged whale from those produced by other nearby whales. One proposed solution has been to detect calls using both hydrophone and accelerometer data to identify signals produced by the tagged animal. Some high-amplitude low-frequency calls can be detected with accelerometers, but the success in using this approach with all calls within and across species is variable. Here, we provide guidance on the role of the physics of sound propagation and the tag hardware's accelerometer capabilities for successful application of this method with examples from tag data collected from fin whales (Balaenoptera physalus), blue whales (B. musculus), and southern right whales (Eubalaena australis). Of 1190 high amplitude calls believed to likely be from the tagged animal, only 517 were also detected on the accelerometer. Reasons for lack of detection were primarily the frequency of the signal lying outside the usable frequency detection range of the accelerometer on the tag, indicating selection of appropriate hardware capabilities are critical for this approach.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 1","pages":"548-556"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144659506","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}

Since sounds can be represented as images in the time-frequency plane, existing few-shot-SED methods often borrow techniques from object detection in image processing, such as the prototypical networks. When applied to bioacoustic SED, however, prototypical networks encounter significant challenges. For instance, the main acoustic targets in a spectrogram are often small. The background is typically noisy, leading to overlap in frequency between positive and negative events. Furthermore, the positive events may be weak compared to the background. To overcome these difficulties, this study introduces an automatic frequency range identification algorithm, which is designed to handle small objects in Mel-spectrograms effectively. After the desired frequency range is identified, the system performs event detection by computing cosine similarity in a gliding-window manner. Overall, the system does not require a large amount of training data, or rely on pretrained models. An F-score of 46.9% was achieved on DCASE 2024 Task 5, placing it on top 3 and demonstrating its potential in addressing the unique challenges of bioacoustic SED.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 1","pages":"123-134"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144575746","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, since these waves possess a supersonic phase velocity (i.e., greater than the speed of sound in fluid), they tend to leak energy into the surrounding liquid, causing undesirable acoustic streaming and compromising manipulation stability. In this work, we introduce a compact acoustofluidic platform that harnesses both a non-leaky quasi-Scholte wave and a leaky Wood's anomaly mode, excited by a piezoceramic plate with a periodic electrode array. The quasi-Scholte wave-arising from the fluid-loaded plate interface-is characterized by its subsonic phase velocity and an evanescent field that is strongly confined near the surface, decaying exponentially into the fluid. This localized field generates a strong negative vertical acoustic radiation force, making it highly effective for particle trapping. In contrast, the Wood's anomaly mode, excited by periodic structural diffraction, produces a weaker but spatially periodic field that exerts a positive vertical force, enabling stable particle levitation. Through frequency tuning, our system enables dynamic switching between trapping and levitation, along with particle movement via phase modulation. Experimental results demonstrate precise, stable, and programmable control over polystyrene microparticles, making this platform energy-efficient, high-throughput, and well-suited for acoustofluidics.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 1","pages":"164-172"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144575750","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}

Reducing the algorithmic latency of a deep neural network charged with noise reduction allows additional time for other processing. However, a larger analysis window may be advantageous to the performance of the network. This trade-off is currently examined with regard to human speech-intelligibility performance. The algorithmic latency of the attentive recurrent network (ARN) was modified by reducing the size of the analysis time frame. The ARN model was talker, noise, and recording-channel independent, and fully causal. Listeners with hearing loss and with normal hearing heard sentences in babble at various signal-to-noise ratios. Large increases in intelligibility were observed as a result of noise reduction, especially for the listeners with hearing loss and at less favorable signal-to-noise ratios. Slightly larger objective measures of network performance were observed at larger latencies. But more critically, human performance was essentially unchanged as algorithmic latency was reduced from 20 to 10 or 5 ms. These results are discussed in the context of overall design and implementation of deep-learning based noise reduction, and information on latency requirements for human listeners is summarized.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 1","pages":"380-390"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144626642","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}
