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.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"2810-2821"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111309","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 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.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"2744-2755"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111367","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}

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.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"2833-2844"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111391","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, conventional acoustic logging is dominated by direct waves, limiting its investigation depth to the near-borehole invasion zone. Full-waveform inversion is a waveform-fitting inversion technique that offers high resolution and is not constrained by assumptions of homogeneity. To reconstruct deep formation properties and structures, we apply the method of borehole reflection waveform inversion to array acoustic logging data. By dividing the array into subarrays and exploiting the spatial correlation of adjoint wavefields, this approach implicitly suppresses crosstalk artifacts in the adjoint-state method under the framework of elastic waves. Additionally, energy weighting and anisotropic diffusion filtering are applied to precondition the gradient, effectively mitigating severe illumination imbalances and high-wavenumber noises. A frequency hierarchy strategy is further integrated to enhance convergence stability. This method provides a theoretical P-wave velocity reconstruction workflow for single-borehole deep acoustic sensing without adding significant computational complexity. Numerical results demonstrate that the proposed method reconstructs complex two-dimensional heterogeneities with high precision.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"3078-3092"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149194978","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}

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.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"2859-2870"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111342","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}

School-age children often perform worse than adults under these conditions, but the component skills responsible for child-adult differences are poorly understood. This study measured masked detection thresholds for three groups of children (5-7, 8-10, and 11-13 yrs) and adults, all with normal hearing. The masker was a continuous stream of four-tone bursts, with the frequencies of those four tones randomized for each burst. The signal was a single tone added to one, two, four, or eight sequential bursts. Signal frequency was either 1000 Hz (fixed) or 1000 Hz ± 0.5 octave, randomly selected for each trial (variable). Overall, thresholds were lower for the fixed than variable signal frequency, and thresholds fell with increasing numbers of repeating signal bursts. Signal-frequency variability had differential effects as a function of age group and number of sequential signal bursts. While some aspects of the data are consistent with maturation of the ability to benefit from signal repetition in the context of a random-frequency masker, more research is needed to understand how segregation and selective attention change with age under these stimulus conditions.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"3068-3077"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149194460","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 speech production, although singers' superiority has been observed relative to non-musicians, little is known about how they achieve this advantage. To address these gaps, this study investigated (i) whether singers outperformed non-musicians in Mandarin tone perception and imitation, (ii) whether singers' potential advantage in imitation depended on auditory feedback, and (iii) whether both groups' imitation improved across repetitions. Singers and non-musicians completed a Mandarin tone AXB discrimination task to evaluate their Mandarin tone perception. As for tone production, they completed a Mandarin tone word imitation task under two conditions-with and without auditory feedback. Results showed that singers achieved higher accuracy in tone perception, extending the OPERA hypothesis from Patel [(2011). Front Psychol. 2, 142; (2014) Hear. Res. 308, 98-108] by demonstrating that vocal training can also enhance auditory sensitivity to speech sounds. The singers also surpassed non-musicians in tone imitation, an advantage independent of auditory feedback, possibly reflecting reliance on somatosensory feedback or feedforward control. No effect of repetition was observed. Additionally, the high-level and high-falling tones appeared to rely more heavily on auditory feedback during imitation.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"160 4","pages":"3040-3056"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149182253","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}
