This study proposes a sparse-aware conjugate gradient-based filtered-x recursive least squares (SCG-FxRLS) algorithm, for which the convergence is theoretically demonstrated. Additionally, the influence of sparse constraint hyperparameters on the algorithm’s performance is thoroughly analyzed.

This integration enhances the algorithm’s capability to adapt effectively to the sound field characteristics within complex environments.

To address these issues, we propose and demonstrate a novel acoustic filter based on the design of a half-wavelength resonator. The developed filter exploits the nodal plane in acoustic pressure distribution, effectively minimizing microphone exposure to targeted ultrasonic frequencies. Fabrication via stereolithography 3D printing ensures high dimensional accuracy, which is crucial for high-frequency acoustic filters. Finite element method simulations guided filter optimization for suppression frequencies at 40 kHz and 60 kHz, achieving high transmission loss around 60 dB. Experimental validations confirm the filter's superior performance in significantly reducing spurious acoustic signals, as reflected in frequency response, beam pattern, and propagation curve measurements.

As an important part of the train, cracks in the axle can lead to serious safety accidents if not detected and treated in a timely manner. Acoustic emission technology can detect cracks at an early stage and, as an online real-time detection method, is essential to ensure the reliability of axles. This technology not only improves the timeliness of fault detection but also provides strong support for train maintenance and management. However, obtaining complete and continuous crack extension data is challenging due to environmental and equipment limitations. Therefore, real-time prediction of crack development during train operation has become particularly important. The real-time prediction of the sequence of acoustic emission signals enables the early detection of potential faults, thus effectively preventing the occurrence of major accidents. Therefore, we propose an improved model based on DLinear, designed for real-time prediction of acoustic emission signal time series. This model innovatively incorporates a multi-head attention mechanism into both the trend and seasonal branches. This unique architectural design enables the trend branch to more accurately capture nonlinear variation features while significantly enhancing the seasonal branch’s ability to analyze high-frequency fluctuating signals.

For each test, nine synthetic alarm signals are generated based on the alarm sounds used in Buenos Aires. The results demonstrate that all four variables significantly influence perceived urgency, with temporal variables exerting a stronger effect than frequency variables. Multiple regression analyses reveal that higher harmonic amplitudes and increased pitch enhance perceived urgency, with harmonic attenuation playing a more dominant role.

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.
