1. Hybrid replica-based reconstruction of target ship noise using blind deconvolution and adaptive time reversal.
PMID:日期:2026-10-01In real ocean environments, multiple ship noises are often received simultaneously, making it difficult to accurately estimate the noise of a specific target ship. In particular, in multipath propagation environments, signal distortion caused by propagation paths further complicates the separation and reconstruction of the target signal. In this study, a hybrid replica-based adaptive time reversal processing (ATRP) method is proposed to reconstruct target ship noise in environments where multiple ship noises are overlapped. First, the Green's function of the propagation path is estimated from the received signals using blind deconvolution, and a hybrid replica is constructed based on the estimated result. The generated replica is then used to perform ATRP, enabling selective reconstruction of the target ship noise. The performance of the proposed method was verified through numerical simulations, and its applicability was examined using real ocean data. The reconstruction performance of ship noise was evaluated based on spectral characteristics and sound pressure levels. The results demonstrate that the proposed hybrid replica-based ATRP method can effectively reconstruct the main spectral characteristics of target ship noise even in environments with overlapping ship noises.

2. Acoustic leak detection in industrial ducts using nonlinear spectrogram remapping and channel attention.
2. 使用非线性频谱重映射和通道注意力的工业管道声学泄漏检测PMID:日期:2026-10-01An acoustic leak-detection framework is presented for industrial ventilation ducts by combining physically motivated spectrogram remapping with attention-guided object detection. Small, pressurized leaks generate broadband turbulent-jet noise, whereas blowers, airflow fluctuations, and structural vibration dominate the lower-frequency field. Preliminary spectra from the test duct showed repeatable leakage energy from 10 to 20 kHz, so this band was expanded during short-time Fourier transformation while low-frequency and out-of-band components were compressed. The remapped spectrograms were processed by a YOLO v5 detector with a Squeeze-and-Excitation channel-attention module. A field dataset of 4780 paired linear and nonlinear spectrograms was collected from a 320-m duct section at the China Jinping Underground Laboratory under three pressures and two aperture sizes. Matched data partitions and ablation tests were used to isolate the effects of the acoustic representation and network architecture. Across the mixed-condition test set, the proposed method achieved 97.1% precision, 95.6% recall, and 95.2% mAP@0.5:0.95, improving precision by 2.7% points over the corresponding linear-spectrogram baseline.

3. Effective model of fiber Bragg gratings for simulation of ultrasonic guided wave measurements using spectral finite elements.
3. 用于谱有限元模拟超声导波测量的光纤布拉格光栅有效模型PMID:日期:2026-10-01This paper deals with the modeling of optical fiber Bragg gratings (FBGs) dedicated to ultrasound measurements. It addresses the problem of modeling the impact of acoustic waves on such small transducers, with typical FBG lengths and optical fiber diameters several orders of magnitude smaller than the ultrasound's characteristic wavelength, especially with guided waves. The method adopted to model the behavior of such transducers can therefore severely affect computational performances and results. We propose here the use of a one-way coupling scheme, limiting the impact on the simulation of ultrasonic waves, while reproducing accurately the FBG transducer's response. This model is validated against experimental data, especially regarding the FBG's spectral response with respect to ultrasonic wavelength.

4. Research on active noise control for villa elevators based on transmission path analysis and complex spectrum learning.
PMID:日期:2026-10-01Villa elevator noise is predominantly concentrated in the 20-500 Hz frequency range, with a reverberation time of 0.2 s, which is far shorter than the 0.4 s of conventional elevators. This makes it challenging for adaptive filters to guarantee effective noise reduction performance. A novel deep learning-based active noise cancellation method is proposed based on Dominant Transmission Path and Complex-spectrum Network (DTPC-Net). First, a transmission path model was established, and the primary noise source and its dominant propagation direction were identified based on coherence analysis and energy distribution. Subsequently, a one-dimensional modeling strategy oriented toward the dominant propagation direction is proposed to address the high computational complexity of three-dimensional modeling. Furthermore, a convolutional recurrent network was designed to estimate the complex spectrum of noise signal. A hierarchical long short-term memory module and a Squeeze-and-Excitation attention module were incorporated to capture dynamically varying noise features. In addition, a predictive compensation mechanism based on blank frame padding was proposed to train the neural network and mitigate system delay. Finally, noise was reduced by 10.29 dB and 8.76 dB when the villa elevator operates at 0.4 m/s and 1 m/s, respectively. And the corresponding A-weighted reductions were 7.62 dBA and 7.54 dBA.

5. Sparse spatial-frequency adaptive learning for enhancing underwater acoustical tonals under impulse noise.
PMID:日期:2026-10-01Enhancing and extracting sinusoidal signals (tonals) is a key challenge in underwater acoustic signal processing. However, conventional tonal enhancement methods deteriorate seriously under high levels of impulse noise. To address this problem, we propose a sparse spatial-frequency adaptive learning method for robust tonal enhancement in the presence of impulse noise. An array signal model is formulated to characterize spatially correlated impulse noise. Based on this model, we exploit the sparsity of tonals in the spatial-frequency domain and develop a sparse spatial-frequency beamforming approach to achieve initial tonal enhancement. To mitigate the false alarms caused by impulse noise artifacts in the resulting azimuth-frequency spectrum, we further introduce an adaptive learning scheme. This scheme exploits the stationarity of tonal signals and the non-stationarity of impulse noise to effectively suppress noise-induced artifacts, thereby achieving a higher output signal-to-noise ratio. The proposed method is validated using both simulated and real experimental data. Comparative results demonstrate that our approach outperforms baseline methods in terms of azimuth resolution and processing gain under impulse noise conditions.

6. Child acquisition of complex consonants: The role of oral motor control in developing acoustic targetsa).
PMID:日期:2026-10-01Our study examines the role of oral motor control in the acquisition of acoustic targets for lingually complex consonants in Estonian by speakers from four age groups. We focus on children's production of secondarily palatalised and non-palatalised consonants where anatomical development and acquisition of motor control skills make differing predictions about the timing and nature of speech production. Our aim is to disentangle the contribution of, on the one hand, speech motor control development and, on the other hand, anatomical growth and articulator change in proportion. We examined oral motor control using a single syllable alternating motion rate diadochokinetic (DDK) task and studied the difference between the second formant (F2) and first formant (F1) using functional principal component analysis. Our results show that palatalised and non-palatalised productions differ significantly across all age groups, indicating children can produce palatalisation contrasts from age 3 years, but consistency in production increases with age. Results also show that children and adults with greater oral motor control skills are better able to produce the palatalisation contrast. These results suggest that anatomical proportions pre-dispose children toward early acquisition of the acoustic properties of palatalisation. However, adult-like production of the phonological contrast also depends on the acquisition of oral motor control skills.

7. Physics-guided Bayesian matrix completion of replica libraries for underwater source localizationa).
PMID:日期:2026-10-01For matched field localization using ship radiated noise as sources of opportunity, replica libraries are often incomplete because vessel trajectories cannot fully cover the observation region. The completion problem can be formulated as recovering missing replica entries from partial observations, for which Bayesian matrix completion methods provide a probabilistic framework. However, the relatively high effective rank of replica libraries constructed from cross correlation functions requires more observations for reliable completion. To address this issue, a physics guided extension of Bayesian matrix completion with graphs (BMCG) is proposed. An envelope transform (ET) is applied to mitigate rapid propagation induced phase oscillations, thereby reducing the effective rank of the replica library. The circular structures revealed by ET are exploited to construct an initialization for BMCG. By incorporating ET-based rank reduction and circular-pattern initialization into BMCG, the proposed method enables reliable replica recovery. Simulations and experimental results demonstrate the effectiveness of the proposed method in localization, with observations of the sources of opportunity available only along a limited number of trajectories.

8. Acoustic emission mechanisms of bubble detachment and pinch-off.
PMID:日期:2026-10-01The evolution of bubbles released from a submerged nozzle involves coupled hydrodynamic and acoustic effects throughout growth, detachment, and ascent. This study investigates the acoustic emission mechanisms of millimeter-scale bubbles using high-speed imaging and hydrophone measurements over a range of gas flow rates. A spherical-cap-cone correction is introduced into the classical force-balance model to characterize the non-spherical morphology of bubbles detaching from large orifices at low flow rates, improving detachment-diameter prediction. With increasing gas flow rate, the classical Minnaert frequency increasingly overestimates the dominant detachment acoustic frequency. A coupled-bubble oscillator model accounting for interactions between newly detached and rising bubbles reproduces this downward frequency shift. Under stable gas supply and nearly axisymmetric detachment, three satellite-bubble pinch-off modes are observed during bubble ascent. Statistical analysis reveals that the dominant pinch-off mode is governed by the competition between inertial-buoyancy effects and surface tension. These events generate distinct acoustic pulses associated with satellite-bubble volume oscillations and re-excitation of the parent-bubble breathing mode, driven by Laplace-pressure perturbations induced by abrupt changes in interfacial curvature. This study clarifies the unsteady dynamics and acoustic emission mechanisms of nozzle-generated bubbles, supporting acoustic monitoring of gas-liquid two-phase flows.

9. Development and evaluation of pk-Ctone: A computationally efficient strategy for enhanced Mandarin tone perception in cochlear implants.
9. pk-Ctone的开发与评估：一种用于增强人工耳蜗普通话声调感知的计算高效策略PMID:日期:2026-10-01Conventional cochlear implant (CI) strategies convey limited tonal information. Although fundamental frequency (F0)-based strategies, such as C-tone, which combines F0 extraction with amplitude envelope modulation, improve Mandarin tone perception, their high computational demands hinder integration into power- and resource-constrained devices. This study evaluates a lexical tone enhancement CI strategy, pk-Ctone, that employs a computationally efficient local extrema-based F0 detection algorithm. Acoustic evaluations on two Mandarin monosyllabic corpora assessed both the coarse-scale robustness and fine-scale fidelity of F0 detection. Computational operations required for F0 extraction were quantified, and a clinical trial with 62 participants compared Mandarin speech recognition using pk-Ctone versus a standard envelope-based baseline. Results showed that pk-Ctone reduced the computational operations for F0 extraction by more than 30-fold compared with C-tone. Although this efficiency gain incurred a penalty in fine-scale precision, pk-Ctone achieved improved coarse-scale robustness, as quantified by Accuracy and F1-score. Clinically, pk-Ctone yielded significant improvements in recognition of monosyllabic tones (+10.1% points, pp), monosyllabic words (+19.2 pp), and disyllabic words (+13.0 pp). These findings indicate that pk-Ctone, by preserving coarse-scale F0 tracking robustness while reducing computational cost, maintains clinical effectiveness despite some loss in fine-scale precision, offering a practical solution for power- and resource-constrained CI processors.

10. Variability in elastic vibration response of additively manufactured materials: A round robin study.
10. 增材制造材料弹性振动响应的变异性：一项循环研究PMID:日期:2026-10-01The rapid growth of research in advanced acoustic materials has been enabled by contemporary growth in additive manufacturing advancement and accessibility. This report provides a quantitative evaluation of variability in the elastic vibration response of structures fabricated using fused deposition modeling. The approach in this study involves assembling a sample set from six institutions via an interlaboratory round robin study. Slender beam samples were fabricated using fused deposition modeling and a standardized commercial filament and printed on whichever commercial printers were available at each institution. To quantify variability in fabrication of both bulk material and metamaterial-inspired features, two sample sets were requested and tested, a set of plain beams and a set of beams with embedded resonator. All samples were measured for dimensional accuracy and dynamic performance using a vibration shaker using a laser Doppler vibrometer. Measured resonance response of each set of samples revealed that the variability between printers was roughly 20% in bulk dynamic properties and as large as 280% in coupled resonator-beam dynamic performance. The study provides design bounds for metamaterial design across various printer hardware and highlights the importance of understanding repeatability using this fabrication approach.
