To address these limitations, this paper introduces a novel deconvolution model that incorporates a non-convex sparse penalty, termed Cyclo-GMCP. Initially, the acoustic map generated by CSCBF is obtained, and subsequently, the point spread function (PSF) within CSCBF is derived to establish the deconvolution model. To ensure high spatial resolution in localization results, a generalized minimax-concave penalty (GMCP) is imposed on the acoustic map.

With the breakthrough development of natural language processing technology, text-based depression recognition has emerged as a promising non-invasive diagnostic approach. Nevertheless, traditional models often suffer from limited feature representation and contextual ambiguity, particularly in Chinese. This study proposes a novel semantic fusion depression recognition model (SFDRM) was proposed by integrating part-of-speech (POS) features with sequential features of text to address these challenges. First of all, an improved TF-IDF algorithm was developed by incorporating the sentiment dictionary with semantic rules, thereafter extracting sentiment-oriented POS based. Second, global semantic representations were extracted using BERT, and local contextual features are captured via BiLSTM. Finally, a self-attention mechanism was introduced to dynamically fuse these multi-granular features, enabling the model to emphasize salient information. Experiments conducted on two publicly available Chinese depression corpora (EATD and CMDC) showed that SFDDM has higher accuracy (0.86) and F1 score (0.80) compared to traditional and single feature models. This indicated that the model effectively addressed the ambiguity problem in Chinese sentiment analysis, and effectively improved the generalization ability and robustness of the model. Therefore, the current SFDRM might provide a more effective and universal solution for intelligent depression screening based on Chinese language patterns, and lays the foundation for the integration of acoustic features in multimodal mental health assessment in the future.</div></div>","PeriodicalId":55506,"journal":{"name":"Applied Acoustics","volume":"242 ","pages":"Article 111084"},"PeriodicalIF":3.4,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145121146","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}

A major contributor to the noise transmitted into the cabin is the tractor engine, which generates a series of harmonic components, predominantly in the low-frequency range (below 1000 Hz). Due to space limitations inside the tractor cabin and the necessity of transparent surfaces to ensure visibility, effective passive noise mitigation can hardly be implemented. Active noise control (ANC) represents a suitable and modern technique to attenuate unwanted noise. This paper presents an experimental evaluation of a multi-channel ANC system applied to a tractor cabin, aimed at reducing the driver’s exposure to noise generated by a four-cylinder engine. The system implements the well-established filtered-X least mean squares (FXLMS) algorithm in a multi-channel feedforward configuration to generate control signals, employing an accelerometer mounted on the engine as a reference sensor. Initial tests were carried out under stationary conditions, by varying the engine’s revolutions per minute. Subsequent tests were performed under different driving conditions on an asphalt ring track, varying gear, range, and crankshaft rotational speed. The results demonstrate the effectiveness of the ANC system in reducing engine-related noise components between 80 Hz and 500 Hz. The low-frequency limit is imposed by the frequency response of the control loudspeakers. To enhance algorithm efficiency, a digital low-pass filter is applied to prevent instability introduced by high frequencies.</div></div>","PeriodicalId":55506,"journal":{"name":"Applied Acoustics","volume":"242 ","pages":"Article 111087"},"PeriodicalIF":3.4,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145109177","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}

Noise can disrupt the algorithm’s accurate estimation of small singular values, leading to the formation of sidelobes. To address this challenge, this paper puts forward an asynchronous measurement sound source localization method that combines truncated nuclear norm and Lp norm minimization. This approach integrates the Lp norm into the existing truncated nuclear norm minimization strategy and uses the Alternating Direction Method of Multipliers (ADMM) algorithm to solve the objective function. For the non-convex sub-problem that contains the Lp norm, a weighted L2 norm approximation technique is introduced and incorporated into the ADMM iteration process. After completing the cross-spectral matrix using this matrix completion technique, the traditional beamforming method is employed to achieve asynchronous measurement sound source localization. To verify the superiority and effectiveness of this method, simulations and experiments of sound source localization are performed under different SNR and frequency conditions. The imaging performances of multiple algorithms are compared. The findings show that the asynchronous measurement approach for locating sound sources, which is based on the combination of truncated nuclear norm and Lp norm minimization, performs better than other models in low-SNR scenarios.
