Although many factors are known to influence the probe response following a masker, the current work focused on the temporal separation (delay) between the masker and probe and the inter-trial interval (ITI). Human probe thresholds recover from forward masking within 150-300 ms, similar to neural threshold recovery in the inferior colliculus (IC) within 300 ms after tone maskers. Our study focused on the recovery of discharge rate of IC neurons in response to probe tones after narrowband Gaussian noise (GN) forward maskers, with varying time delays. Additionally, we examined how prior masker trials influenced IC rates by varying ITI. Previous masker trials affected probe-evoked discharge rates, with full recovery requiring ITIs over 1.5 s after 70 dB SPL narrowband GN maskers. Neural thresholds in the IC for probes preceded by noise maskers were in the range observed in psychoacoustical studies. Two proposed mechanisms for forward masking, persistence, and efferent gain control, were tested using rate analyses or computational modeling. A physiological model with efferent feedback gain control had responses consistent with trends in the physiological recordings.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 5","pages":"3680-3693"},"PeriodicalIF":2.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143971164","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}

Its architecture reflects the intent of Richard Wagner (1813-1883) to craft a new German opera house: among other innovations, the Festspielhaus introduced an orchestra pit. Although the idea of the orchestra pit is not original, the sum of the outcomes of the Festspielhaus has made this solution revolutionary, beyond the boundaries of the site-specific nature of the building. Focusing on architectural acoustics, this study seeks to emphasize the impact of the orchestra pit. Based on measurements, the multiple functions performed by the orchestra pit are highlighted, starting with balancing the sound of a large orchestra and the intelligibility needs of the soloist's voice. A large amount of non-technical literature was deeply investigated to find matches with objective results and complementary knowledge, such as the limited communication between the orchestra pit and the stage and the poor listening from the conductor's position. Like many groundbreaking processes, the Bayreuth orchestra pit was shown to brilliantly solve acoustic challenges but also evidences limitations, progressively abandoned in the natural evolutionary process of performance spaces.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 5","pages":"3436-3449"},"PeriodicalIF":2.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143988488","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}

The framework involves three primary steps: peak detection, mode decomposition, and component identification. By employing spectral analysis and spectral proper orthogonal decomposition, the framework extracts key information on discrete tonal frequencies, amplitudes, and waveforms, reconstructing coupled hydrodynamic and acoustic pressures into new modal representations. Component decomposition is further achieved through wavenumber-frequency spectrum analysis, revealing the characteristic phase velocity of the reconstructed modes. An acoustic experiment was conducted using a microphone array to evaluate the noise identification performance. The findings indicate four characteristic zones within the fluid dynamic and acoustic pressure pulsations, with acoustic components prevailing in the low and mid-frequency ranges, particularly associated with large-scale vortex structures. Finally, the production mechanisms of the identified hydrodynamic and acoustic pressure pulsations were further revealed by solving the eigenvalue problem of the compressible linearized Navier-Stokes equations in the frequency domain. The results support that the decomposed sound pressure features a low attenuation factor, allowing for long-distance propagation with minimal loss.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 5","pages":"3402-3417"},"PeriodicalIF":2.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144026669","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}

Deep learning-based methods have gained popularity in recent years because of their strong performance. However, these methods often fail to generalize well in real-world scenarios. This work reveals one underlying challenge: the characteristics of ship-radiated noise are influenced by factors such as vessel structures and propulsion systems. Although vessels of the same type may exhibit different patterns in these aspects, vessels of different categories share similarities. As a result, data-driven models often tend to overemphasize individual-specific features, leading to \"overfitting\" and poor generalization. The momentum-based adversarial training (MBAT) framework is proposed to mitigate this challenge. MBAT leverages a momentum adversarial strategy to use category information and individual vessel relationships, helping extract class-discriminative features. A homoscedastic uncertainty algorithm is employed to balance the optimization objectives of category-related and vessel-specific features. These strategies allow the model to capture category-discriminative patterns more effectively and generalize to unseen targets. Experiments on DeepShip and ShipsEar demonstrate that MBAT significantly improves generalization capability on unseen individual vessels, outperforming existing state-of-the-art methods. Visualizations further confirm the efficacy and necessity of the proposed approach.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 5","pages":"3508-3523"},"PeriodicalIF":2.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143970957","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, the axial localized point-like focal spots formed in previous studies cannot provide clear imaging of curved objects with finite spatial thickness. Here, we propose an acoustic needle metalens (ANM) composed of high-throughput spiral units with a specific phase distribution. According to the caustic theory, the designed ANM can generate two parabolic accelerating beams along the pre-designed path, ultimately forming a non-localized needle-like focal spot. We numerically simulate and experimentally verify the focusing property of the ANM at 8.5 kHz. The results indicate that the focal depth of the ANM is 50.63 times the wavelength while maintaining a transmission coefficient above 0.9 for each spiral unit constituting the ANM. Moreover, non-axial acoustic needle focusing has been achieved by altering the trajectory equations of the two parabolic accelerating beams. We further experimentally examine the excellent imaging capability of the designed ANM by conducting acoustic imaging on curved objects with a thickness of three wavelengths. The proposed ANM will have potential applications in microfluidic manipulation and medical ultrasound imaging.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 5","pages":"3474-3481"},"PeriodicalIF":2.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144016881","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}

Specifically, phonological and semantic relationships between spoken words have been observed to influence a listeners' ability to discriminate voices. This study aims to develop our understanding of how different kinds of linguistic relationships, namely, phonetic relationships, influence the processing of speaker information. We conducted two experiments, a voice discrimination task and a voice similarity rating task, in which listeners were presented with pairs of speakers producing two words with various degrees of phonetic overlap. On the whole, higher quantities of phonetic overlap corresponded to higher speaker discrimination performance and higher similarity scores; however, the type of the phonetic overlap also mattered. Overlapping vowel segments showed substantial utility, while overlap of the phonological rhyme alone substantially lower performance. Results from this condition suggest that a phonological relationship within the word pair can interfere with otherwise increased quantities of phonetic overlap. These findings highlight the salience of the phonological rhyme in voice processing, as well as the overall impact of phonetic overlap.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 5","pages":"3572-3589"},"PeriodicalIF":2.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144006098","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 this study, a contrastive pseudo learning framework is proposed to design the data-driven ship-radiated noise recognition (SRNR) system, which is suitable for edge computing devices such as wave gliders. In particular, a time-frequency soft re-weighted module is applied to calculate soft thresholds in time and frequency domains to achieve feature fusion and adaptive suppression of interference. Additionally, fullband-subband contrastive learning is introduced to guide feature alignment and integrate global and local information for acoustic representation enhancement. Other than that, contrastive pseudo labeling is employed to use a large scale of unlabeled data with limited amounts of labeled data for semi-supervised learning. Extensive experiments along with sea trials show that the proposed method achieves the state-of-the-art performance on SRNR in noisy, real-world conditions.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 5","pages":"3358-3369"},"PeriodicalIF":2.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143998747","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 total of 1409 participants, grouped by their proximity to the construction sites, completed a socio-acoustic survey on their personal situation and noise perception. Noise levels were monitored using 18 autonomous stations near the construction sites. Findings showed that a significant portion of participants experienced annoyance due to construction noise, though annoyance levels decreased significantly over time in both groups. Interestingly, those living closer to the construction sites reported a faster decline in overall construction noise annoyance and annoyance from other aspects of the work undertaken. Regression models indicated that construction noise levels explained only a small portion of annoyance variance. Key contributing factors included annoyance from other construction nuisances, noise perception in the bedroom, and perceived safety. This study provides valuable insights for future development of policy concerning noise on construction sites. Specifically, the results suggest that taking into account identified socio-demographic, psychosocial, and contextual variables, as well as the individuals' perception of noise levels and construction-related nuisances, could help to reduce construction noise annoyance, ultimately improving the quality of life for nearby residents.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 5","pages":"3590-3603"},"PeriodicalIF":2.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143989219","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}
