These surveys, particularly multichannel ones, help observe mesoscale features like ocean fronts, eddies, and internal waves. Airguns, commonly used as sound sources in these surveys, generate a desired primary pulse followed by unwanted bubble oscillations that are termed bubble waves (BWs). These BWs can degrade seismic data accuracy, especially in shallow water and when capturing faint water column reflections. This article reviews the history of seismic sound sources, bubble formation physics, source signatures, and the acoustic multipath structures of the signal. It also covers applications of seismic data in water column imaging and sound propagation for environmental impact assessments. Given that bubble oscillations affect data quality, the article highlights recent advancements in mitigating BW effects, including larger airgun arrays, debubbling through simulation techniques, and advanced signal processing. Furthermore, it explores the potential of artificial intelligence (AI) techniques, such as physics-informed neural networks and hybrid methods, to enhance seismic data quality. These AI-based approaches aim to improve imaging accuracy and reliability, particularly for faint water column reflections.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2420-2447"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145137851","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 disruption occurs across all ages, with infants and older adults being particularly vulnerable. In infancy, when robust speech encoding is fundamental for native language acquisition, the presence of background noise could have significant consequences for the development of speech and language processing. This study investigates the impact of background noise on the neural encoding of speech sounds in neonates. We recorded the frequency-following response to a /da/ syllable in both quiet and noise conditions from 25 healthy-term neonates and 21 normal-hearing adults. Results revealed higher neural responses in the adult group compared to newborns. Both groups exhibited reduced spectral amplitudes in the noise condition, with adults showing a greater decrease in the fundamental frequency spectral amplitude during the consonant transition compared to the steady vowel section. In contrast, neonates displayed similar disruption across both sections, possibly reflecting their immature auditory systems and limited exposure to higher-frequency formants in utero. This study represents a first step toward understanding the development of speech-in-noise processing from birth.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2577-2589"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145137872","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}

Indeed, previous results suggest that insufficient audibility of \"speech glimpses\" may partly explain the poor performance of listeners with hearing loss in multitalker mixtures. An implication of those results is that restoring audibility across the spectrum may be especially critical in such situations. The current study investigated whether current hearing-aid amplification strategies adequately restore the audibility of speech glimpses. Ideal time-frequency segregation was used to isolate target speech glimpses from unaided and aided speech mixtures. Intelligibility was then measured for the isolated glimpses and for the original mixtures. Participants were young adults with bilateral sensorineural hearing loss, and individualized non-linear amplification with fast-acting compression was provided using the open Master Hearing Aid. Results showed that amplification generally improved the audibility and intelligibility of the target speech glimpses, but the benefit was diminished in the mixture, suggesting that there were counteracting effects. This approach may provide a useful way to unpack positive and negative effects of hearing-aid processing in multitalker mixtures.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"1637-1645"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12456456/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144958645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these structures' spatial sampling characteristics can easily lead to spatial aliasing phenomena. To tackle this issue, this paper introduces an underwater acoustic beamforming method that utilizes the acousto-optic deflection effect. This method exploits the deflection mechanism of acousto-optic interaction, using laser beams that traverse the acoustic field to continuously integrate acoustic signals. Each segment of the laser beam can be considered as an individual acoustic sensor, deflecting in accordance with the modulation of the propagating sound wave, thereby forming a laser array with continuous, infinite aperture characteristics. This design fundamentally circumvents the discrete summation mechanism of conventional finite-number hydrophone arrays, effectively eliminating the spatial aliasing problem. In addition, the laser converts complex underwater acoustic signals into deflection angle information as it passes through the acoustic field, achieving high sensitivity through the light path extension technique. Experiments demonstrate that the proposed method successfully extends the beamforming system's effective anti-spatial aliasing bandwidth to the frequency range from 20 to 80 kHz. Specifically, a laser propagation path of only 17 cm achieves angular resolution equivalent to that of an 18-element hydrophone array.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2331-2343"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145125044","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 elevation angle estimated by an ocean bottom seismograph may not be satisfactory, leading to mismatch issues for the matching processing algorithm and resulting in inaccurate range and depth estimation results. To overcome this problem, the multidimensional matched sound intensity processing (MD-MSIP) method is proposed. The MD-MSIP is defined as a joint estimation of the initial range, the target speed, the closest point of the approach range, and the source depth. By matching these four preset parameters, the target can be located, which does not require the elevation angle when calculating the replica field, avoiding the influence of the elevation angle error on MSIP. The experimental results demonstrate that the relative errors of the depth and range estimation results can be controlled within 10% and 20% by MD-MSIP, respectively. The target trajectory can also be estimated using the azimuth. In addition, the robustness of MD-MSIP is enhanced during the mismatch of the sound speed profile using the slow phase variation characteristics of the low-frequency signals.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2032-2047"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145033444","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 ability requires the dolphin to extract useful information from complex echoes with differing inter-highlight intervals (IHIs). The current experiment tested the abilities of dolphins to discriminate between simulated echoes with a standard IHI and those with a slightly longer IHI. Seven standard IHIs were tested from 50 to 750 μs. Testing occurred with the two echo highlights in-phase and also with each highlight given a random phase shift. For standard IHIs <300 μs (within the auditory temporal window), thresholds for the in-phase condition were an order of magnitude lower than in the random phase condition. These results are consistent with a reliance on the interaction of the fine structure of the two echo highlights to discriminate small differences in IHI that become \"blurred\" for the random phase condition, resulting in elevated thresholds. For standard IHIs >300 μs (outside the temporal window), thresholds were higher than those for standard IHIs within the temporal window, and were similar between the two phase conditions, suggesting the use of timing differences between the highlight envelopes.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2022-2031"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145033470","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}

All had a fundamental frequency of 50 Hz and were generated using different component phase relationships to yield repetition rates of 50, 100, 200, or 450 pulses per second (pps). In experiment 2, cochlear-implant listeners loudness-balanced electrical pulse trains presented to a single electrode, also at durations of 40, 120, and 400 ms. The pulse trains had rates of 100 and 2000 pps. Both experiments showed that lower-rate stimuli needed a higher level to match the loudness of higher-rate stimuli, with this effect decreasing with increasing duration. In experiment 2, this duration effect was only observed in trials where the 2000-pps train was presented before the 100-pps train, consistent with the idea that participants compared the end of the first stimulus in each trial to the start of the second.

It was hypothesized that greater angular elevation would enhance distance estimation accuracy. Results confirmed this, suggesting that spatial hearing is influenced by geometric cues related to source elevation. Experiment 2 replicated the task using only roved intensities with 21 seated participants, resulting in reduced angular elevations of 36.9°, 24.4°, 16.6°, and 11.5°. Under these conditions, participants showed no significant difference in distance perception between floor-level and ear-level sources.

A technique was developed to extract, from minutes-long speech samples, the time-dependent fundamental frequency (fo) and the first two formant frequencies (F1 and F2) to permit an analysis that determines whether a talker aligns a voice source harmonic with a vocal tract resonance, and also measures a normalized vowel space area. The accuracy of the processing method was validated by applying it to a set of audio samples generated via speech simulation that provided \"ground-truth\" data. It was then applied to a 41-talker database of clear and conversational speech. Results indicated that talkers make adjustments for different speaking styles that include not only increased vowel space area but also alignment of harmonics and formant frequencies, although future work is needed to determine whether these adjustments are directed toward maximizing transfer of information or transfer of acoustic power.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2207-2224"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145086460","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}

One of the challenges in PAT is the ill-posed nature of the inverse problem, where limited measurement data and noise often lead to inaccurate reconstructions. This work introduces a kernel-based regularization (KBR) approach for model-based reconstruction algorithms in photoacoustic (PA) imaging. The proposed method leverages kernel-induced feature space to enforce smoothness and spatial coherence in the reconstructed images, thereby improving the robustness to noise and data sparsity. By incorporating prior knowledge of the signal dynamics for solving the PA inverse problem, KBR enhances the reconstruction fidelity, especially in regions with low signal-to-noise ratio. Numerical experiments and phantom studies demonstrate that the proposed algorithm outperforms traditional regularization techniques, such as Tikhonov and total variation regularization, regarding reconstruction accuracy and computation speed. The results suggest KBR provides a powerful tool for addressing the inherent challenges in PA image reconstruction, offering potential improvements in several applications.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2495-2505"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145137821","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}
