One strain, the Belgian Waterslager canary, has been bred for loud, low frequency song and coincidently has been found to have a high-frequency hearing loss due to damaged and missing hair cells in the basilar papilla. Here, we investigated the possible genetic basis for this hearing loss in the Belgian Waterslager canary by conducting whole-genome Illumina (San Diego, CA) sequencing in three canary strains. We identified a total of 16 Belgian Waterslager male-specific \"high-impact\" single nucleotide polymorphisms (SNP) variants with three mutations occurring within genes previously identified in mammalian hair cell abnormalities and hearing loss disorders: pericentriolar material 1 (PCM1), p21 (RAC1) activated kinase 3 (PAK3)-like, and protein tyrosine phosphatase receptor type K (PTPRK). Interestingly, we also identified three male-specific \"high-impact\" SNP variants in one of our control strains: the American Singer canary. One of these mutations occurs within genes previously associated with hearing loss in mammals. Since songbirds rely on hearing to develop a normal vocal repertoire, investigating the role of these genes in hearing loss at the molecular level may provide a valuable animal model for examining the relationship between hearing loss and vocal development in humans.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 4","pages":"2330-2335"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143753288","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 temperature directly influences the liquid's surface tension, viscosity, and the bubble's spherical shape. These properties, in turn, affect the bubble expansion rate and collapse intensity. Thus, temperature plays a crucial role in the formation, growth, and collapse of bubbles. This study investigates the radial oscillation stabilities of microbubbles, considering the environmental temperature, functional acoustic pressure generator, bubble oscillation frequency, and initial radius. Using methods from dynamical systems theory, including fractal dimension, bifurcation diagrams, time-series analysis, and phase portraits, we analyze the microbubble responses and demonstrate the transition from chaotic to stable oscillations. Multifractal analysis reveals that acoustic pressure, temperature, and initial bubble radius significantly influence bubble dynamics. Higher temperatures result in more energetic oscillations and faster collapse rates. Surface tension is a key factor; higher temperatures reduce surface tension, which can increase bubble stability. The initial radius also impacts stability, with smaller bubbles exhibiting greater stability and larger bubbles being more prone to violent collapses.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 4","pages":"3133-3147"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143971194","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 channel type leads to severe inter-block interference (IBI) in zero-padded single-carrier block transmissions. In this paper, we propose a two-step equalizer based on joint channel estimation (CE), IBI cancellation (IBIC), and symbol detection (SD), termed JCE-IBIC-SD. The proposed equalizer effectively suppresses IBI through iterative CE and symbol detection, even with insufficient training sequences. In the first step, considering the large separation between multipath clusters, the equalizer decomposes deep-sea channels longer than one block into quasi-synchronous channels and retrieves the symbols for all blocks through IBIC and equalization. In the second step, based on the a priori knowledge of the symbols, the JCE-IBIC-SD is applied. Using the damped Gaussian generalized approximate message passing sparse Bayesian learning algorithm, iteratively computes the maximum a posteriori estimates of both the channels and symbols through within a joint factor graph model. Simulations and deep-sea experimental results demonstrate that, even when the receiving array is located in the acoustic shadow zone, the proposed equalizer outperforms traditional IBIC equalizers with reasonable computational complexity.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 4","pages":"2709-2727"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144015174","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 work focuses on identifying the spatial and speed-dependent directivity patterns of a broad range of road-traffic vehicles (including electric, hybrid, and combustion-powered vehicles) by utilizing time-variant wave backpropagation on microphone array signals. The derived directivity patterns are compared to the analytical Harmonoise model and further analyzed for their spectral properties in third-octave bands, as well as their speed-dependent sound power. Besides drivetrain technology, the results highlight the crucial influence of driving conditions, particularly the engine's rotational speed (related to the engaged gear), on the directivity patterns. Being more symmetric in the median plane, asymmetric and more directional patterns are observed in the sagittal plane. At the same speed, the sound power level of individual cars varies in a range between 10 and up to 20 dBSWL, converging at higher speeds. The results are published in an accompanying open-access database containing directivity patterns and sound power in the speed range between 10 and 120 km/h, using standardized Spatially Oriented Format for Acoustics and OpenDAFF data formats for noise mapping and auralization applications.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 4","pages":"2735-2749"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144016449","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}

Generally, higher roughness values are thought to be associated with increased discomfort. However, contradictory phenomena have also been observed, e.g., the recent study [Huang, Lv, Ni, and Jiang, J. Acoust. Soc. Am. 154(4), 1963-1976 (2023)] found that the discomfort was predominantly influenced by loudness and exhibited a negative correlation with roughness for the aircraft cabin noise. To further investigate the influence of roughness metric on noise discomfort, two groups, each comprising 48 participants, rated the discomfort caused by aircraft cabin noise and amplitude-modulated (AM) sounds with modulation frequencies in the 10-140 Hz range, respectively. The discomfort values of aircraft cabin noise exhibit an insignificant correlation with Zwicker roughness metric (r = 0.159, p > 0.05) and a significant negative correlation with Sottek roughness metric (r = -0.640, p < 0.01). By measuring discomfort values of AM sounds, a modulation-frequency-dependent weighting curve was established. The roughness values, adjusted by replacing the weighting curve in the Sottek roughness model, displayed a significant positive correlation with discomfort values (r = 0.713, p < 0.01). This indicated that the modified roughness metric can directly represent the adverse effect of rough characteristics of noise on comfort.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 4","pages":"2763-2773"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144006924","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 paper introduces a two-dimensional (2D) adaptive multichannel decision feedback equalization (DFE) technique with a multi-directional structure, specifically designed for OTFS-based UWA communication system. Two distinct multi-directional architectures are designed, each capitalizing on the 2D modulation characteristics of OTFS to mitigate error propagation across different directions, resulting in diverse error patterns and locations. The first architecture employs a parallel combination approach, consolidating outputs from multi-directional DFEs to enhance performance by exploiting the low correlation among different directional DFEs. Optimal weight factors for this multi-directional setup are derived. The second architecture adopts a serial approach, in which the outputs from other directional DFEs inform the symbol decision process of the current directional equalizer, thereby accelerating the convergence of the equalization process. Simulation and experimental results conducted in lake environments validate the efficacy of the proposed multi-directional 2D DFE algorithm. Comparative analyses reveal its significant outperformance over traditional 2D DFE methods, demonstrating superior symbol detection capabilities relative to other equalization strategies, especially under conditions characterized by limited pilot resources and channel estimation accuracy.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 4","pages":"2657-2670"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143811583","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}

Not only capturing the distance to obstacles but also classifying objects is crucial for advanced driver assist systems and ultrasonic perception. However, current single-element sensors are constrained in classification performance due to a lack of directional information that they are able to capture. In this study, we propose replacing the conventional single-element sensor with a small 2 × 2 array sensor to increase object classification accuracy. The array sensor enables the incorporation of directional information, enhancing target discrimination, even in the compact design of 2 × 2 elements. Further, we propose an efficient convolutional neural network (CNN) to classify preprocessed transducer signals based on experimental data. Several feature extraction methods using the delay-and-sum beamformer, minimum variance distortionless response beamformer, acoustic source maps, and an end-to-end approach are evaluated. Promising classification accuracies are achieved for the array sensor when feeding both the preprocessed transducer signals and an acoustic source map into the CNN, significantly outperforming the conventional single-element sensor. Ultimately, this paper demonstrates the potential of enhancing object classification in ultrasonic surround sensing using small aperture array sensors and leveraging directional information.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 4","pages":"2556-2569"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143795874","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 tones /21, 241, 24/ are associated with lower, diphthongal vowels and non-modal phonation, while tones /44, 51, 32, 5/ are associated with higher, monophthongal vowels and modal phonation. This study tests the hypothesis, based on the laryngeal articulator model (Esling et al., 2019), that epilaryngeal constriction responsible for non-modal phonation mediates vowel quality alternation due to articulatory synergy with lingual retraction. The most common phonation type observed among 18 speakers is harsh voice (with occasional aryepiglottic trilling). Creaky and modal voice, and less often ventricular or whispery voice, are also observed. Spectral tilt and noise measures reveal that noise (cepstral peak prominence and harmonic-to-noise ratio) is most reliable in distinguishing modal from non-modal tones. The only spectral tilt measure that does so is H2-H4, while H1-H2 differentiates subtypes of constricted phonation. The relationship between phonation and vowel quality is also examined. Noisier phonation is associated with higher F1 for all vowels, lower F2 for [ei], and higher F2 for [ou], in accordance with cross-dialectal variation (Chen, 1998), supporting the hypothesis that tone-vowel interaction is mediated by epilaryngeally constricted phonation.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 4","pages":"2582-2602"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803676","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 work examines two key design choices for a CNN classifier: input representation and network architecture, analyzing their importance as training data size varies and their effectiveness in generalizing between sites. Passive acoustic data from three offshore sites in Western Scotland were used for hierarchical classification; categorizing sounds into one of four classes: delphinid tonal, delphinid clicks, vessels, and ambient noise. Three different input representations of the acoustic signals were investigated along with four CNN architectures, including three pre-trained for image classification tasks. Experiments show that a custom-built shallow CNN can outperform more complex ar chitectures if the input representation is chosen appropriately. For example, a shallow CNN using Mel-spectrogram normalised with per channel energy normalization (MS-PCEN) achieved a 12.5% accuracy improvement over a ResNet model when small amounts of training data are available. Studying model performance across the three sites demonstrates that input representation is an important factor for achieving robust results between sites, with MS-PCEN achieving the best performance. However, the importance of the choice of input representation decreases as the training dataset size increases.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 4","pages":"3017-3032"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144026636","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 ablation results in an expanding plasma, which induces a shock wave in the material with a peak compression stress of a few GPa. Starting from an optical microscopy visualization of the weaving, a differentiation between resin and fibers and a segmentation of the fibers lead to an evaluation of the material's local elastic properties below the laser spot position. The shock propagation is simulated using a nonlinear source model, combined with a time domain finite difference discretization of the equations of linear elastodynamics with Lebedev's scheme adapted to the material anisotropy.
