Hyperfunctional dysphonia is a functional voice disorder caused by excessive vocal muscle activity. The vibrations of vocal folds (VFs) are essential for maintaining voice quality, and their kinematic parameters provide valuable insights into voice disorders. This study presents a kinematic model for simulating various VFs vibration patterns associated with hyperfunctional dysphonia. The model evaluates both symmetrical and asymmetrical left–right vibratory phases, providing a visual representation of VFs shape and motion through synthetic kymograms. Validation is performed by comparing these synthetic kymograms with those from previously published studies, using error metrics based on glottis area differences, Structural Similarity Index Measure (SSIM), and Oriented Fast Rotated Brief (ORB) similarity metrics. Each technique is applied to four different phonation types with varying initial oscillation phase values. Results indicate that the proposed model achieves low error value in the first validation technique, with minimum and maximum error values of 0 and 0.0005 for symmetry, and 0.00035 and 0.0932 for asymmetry, respectively. Furthermore, it demonstrates strong similarity between the second and third validation techniques, with maximum and minimum similarity values of 1 and 0.857 for symmetry, and 1 and 0.70393 for asymmetry, respectively. This model enhances the understanding of mucosal wave (MW) dynamics and improves the diagnostic capabilities for hyperfunctional dysphonia in kymographic imaging. By offering more comprehensive view of VFs motion, it facilitates better interpretation of the diverse features relevant to diagnosing hyperfunctional dysphonia.</div></div>","PeriodicalId":55506,"journal":{"name":"Applied Acoustics","volume":"240 ","pages":"Article 110906"},"PeriodicalIF":3.4,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144517419","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 reproduction methods have been proposed to optimize the driving weights to improve reproduction performance for a given loudspeaker array configuration. Recently, various methods have explored to optimize loudspeaker placement for further improving the performance of multizone sound field reproduction. However, these methods are currently based on the pressure matching method to carry out the placement optimization study. This paper proposes a loudspeaker placement optimization method based on modal domain. An optimization model for multizone sound field reproduction is used to determine the global modal coefficients that enable the desired sound field to be accurately reproduced in the bright zone while limiting the whole sound field energy within the dark zone, where the global modal coefficients are transformed to the local modal coefficients by the harmonic translation theorem. The constrained matching pursuit method is used to select the optimal loudspeaker placement according to the obtained global modal coefficients. The driving weights of the selected loudspeakers are calculated by the pressure matching method. The simulation results and experimental results demonstrated the good potential of the proposed loudspeaker placement optimization method in multizone sound field reproduction.</div></div>","PeriodicalId":55506,"journal":{"name":"Applied Acoustics","volume":"240 ","pages":"Article 110904"},"PeriodicalIF":3.4,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510706","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}

Conventional leakage prediction models suffer from computational inefficiency and reduced generalizability due to high-dimensional feature spaces and redundant parameters. To overcome these limitations, this study introduces an interpretable hybrid framework integrating Random Forest (RF)-driven feature selection with Pearson correlation analysis for high-precision leakage diagnostics. Vibration signals were systematically acquired from paired upper and lower flanges at leakage-critical regions, followed by extraction of multicomponent features including total vibration energy, spectral kurtosis, centroid frequency, Shannon entropy, and bidirectional cross-correlation metrics. Through rigorous RF-based recursive feature elimination, four dominant sensitivity indicators were identified: inter-flange cross-correlation (CC), upper-flange centroid frequency (CF), total vibration energy (TVE) of both flanges, and downstream entropy (DE). Subsequent Pearson correlation mapping revealed minimal collinearity (|<em>r</em>| < 0.4) between CC, CF, and lower-flange TVE, establishing these orthogonal features as prediction model inputs. A Multilayer Perceptron (MLP) network is trained to establish the leakage prediction model. Experimental results demonstrate high accuracy of the proposed method, achieving a mean squared error (<em>MSE</em>) of approximately 6.8 and a coefficient of determination (<em>R<sup>2</sup></em>) of 0.97.

The equivalent parameters of the linear thermoacoustic theory were obtained by using the reconstructed 3D random microstructure model and JCAPL model. Then the impedance tube model was established to calculate the sound absorption coefficient of the porous fiber material under the uneven temperature field. The results show that the influence of thermoacoustic effect on the sound absorption coefficient is mainly in the middle and low frequency, and the influence amplitude is extremely dependent on the frequency. When the temperature gradient is 20 K/mm, the absorption coefficient will reach the minimum value of −5.53 at 90 Hz. At 290 Hz, the absorption coefficient reaches 0.88, which is 17.6 times higher than 0.05 when the thermoacoustic effect is not considered. The influence of the thermoacoustic effect on the absorption coefficient decreases as the interface temperature increases. Conversely, the impact of the thermoacoustic effect intensifies with a greater absolute value of the temperature gradient. When the temperature gradient is negative, the sound absorption coefficient becomes negative in the mid and low frequency ranges. Additionally, a reduction in porosity and fiber radius leads to an increased influence of the thermoacoustic effect on the absorption coefficient.

As a result, a helicopter that is type certified may still produce noise levels that are perceived as annoying during normal operations. Specifically, noise certification metrics are not intended to track subtle yet important differences in annoyance perception, especially for the variety of sounds associated with different helicopter maneuvers. A psychoacoustic test is carried out to measure the variation in annoyance to helicopter maneuvers of equal A-weighted Sound Exposure Level (SEL). Results show that helicopter noises of equal SEL are not equal in terms of annoyance. A subset of helicopter noise stimuli are presented at higher or lower SEL, allowing changes in annoyance to be associated with changes in SEL and other metrics. Results show high correlation between annoyance and conventional, time-integrated noise certification metrics like SEL and Effective Perceived Noise Level (EPNL) but also between annoyance and newer loudness-based metrics. Just-noticeable-differences in these metrics are calculated and show how much a metric must change to result in 75% agreement in the annoyance difference.
