Previous literature has provided evidence of an age-related decline in AM frequency selectivity. Additionally, a notable sharpening of AM tuning with hearing loss has been observed, which was proposed to be related to a perceptual advantage resulting from peripheral compression loss. This study explores whether such changes in AM tuning with age and hearing loss contribute to the speech intelligibility challenges older listeners often face in noisy environments. Young (n = 10, aged 22-28 years) and older (n = 9, aged 57-77 years) listeners with normal hearing as well as older listeners with hearing impairment (n = 9, aged 64-77 years) participated in the study. All had previously taken part in studies on AM tuning. Speech-reception thresholds (SRTs) were collected under conditions including stationary, fluctuating, and competing-speech maskers. The results revealed an age-related increase in SRTs, with an additional negative impact of hearing loss. Beyond age and audibility, a measure of AM tuning significantly contributed to explaining the variance in SRTs across listeners for specific maskers. These findings motivate further exploration of the relationship between AM frequency selectivity and speech intelligibility in noise.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 3","pages":"2077-2090"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143700700","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}

To probe the adaptive behaviors bats employ to mitigate the effects of clutter, this study quantified echolocation call features and head movements of big brown bats (Eptesicus fuscus) as they tracked a moving prey target in the dark. Bats were trained to rest on a perch and track an approaching target for a food reward. Clutter was positioned at different distances and angular offsets from the bat and the path of a moving target. This study hypothesized that bats dynamically adjust call features and head direction to facilitate target localization in the presence of clutter. The results show that bats shortened call duration and interval and increased head movements when the target was close to clutter. The study also revealed that bats increase the production of sonar strobe groups in cluttered environments, which may sharpen sonar spatial resolution. Spectral analysis showed that maximum call power shifted to lower frequencies when clutter was close to the target. These data demonstrate the big brown bat's range of adaptive behaviors that support target tracking in cluttered environments.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 3","pages":"2236-2247"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143719925","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, applying conventional frequency-domain equalization (FDE) algorithms to CPM signals over time-varying UWA channels considerably degrades performance. Moreover, time-domain equalization algorithms often rely on excessive approximations for symbol detection, compromising overall reception. This study presents an iterative-detection-based time-domain adaptive decision feedback equalization (ID-TDADFE) algorithm that tracks channel variations through symbol-by-symbol detection. The symbol detection in ID-TDADFE fully considers the inherent coding gain of CPM signals can be cascaded with an adaptive equalizer, and enhances symbol detection performance by utilizing joint probability estimation. Numerical simulations with minimum-shift keying (MSK) and Gaussian MSK signals demonstrated that ID-TDADFE significantly improved communication performance over a time-varying UWA channel within one or two iterations. In a sea trial for experimental verification, ID-TDADFE reduced bit errors by 45.08% and 51.8% in the first and second iterations, respectively, compared to FDE.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 3","pages":"1912-1925"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143657579","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}

To investigate these relationships, measurements were conducted to quantify spatial variability in the upper few decimeters of sediment near the water-seabed interface within a fine-grained sediment deposit on the New England continental shelf. At each measurement location, an acoustic multicorer was deployed to sample the seabed. Acoustic probes were inserted into the sediment to collect direct in situ measurements of sediment compressional wave speed and attenuation (30-100 kHz) under near-ambient conditions, after which cores were collected from the inter-probe propagation paths. Sediment physical properties, organic carbon, infaunal community composition, and ex situ compressional wave speed and attenuation spanning two frequency decades (104-106 Hz) were subsequently measured in the laboratory. The frequency dependence of sound speed ratio and attenuation was analyzed in the context of sediment acoustics models for mud based on the viscous grain shearing and extended Biot models. Sites with greater abundance of larger-bodied infauna (>1 mm) displayed higher variability in sound speed and attenuation. Correlation was found between sediment compressional wave modulus and total organic carbon, suggesting that organic matter in the sediment matrix also affects bulk acoustic properties.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 3","pages":"1686-1702"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143615716","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}

While animal studies have shown that this neural deafferentation reduces wave I amplitudes of the auditory brainstem response (ABR) at suprathreshold levels, studies in humans with tinnitus have reported conflicting results. To enhance the sensitivity of ABRs in detecting neurophysiological conditions associated with tinnitus, this study aimed to examine chirp-evoked ABRs in normal-hearing individuals with tinnitus using the maximum length sequence (MLS) technique. Chirp stimuli improve synchronous neural discharge during ABR recording, while the MLS technique enables the extraction of evoked responses from overlapping waveforms. We hypothesized that this combined approach would more effectively reveal ABR morphological characteristics associated with tinnitus. The results indicated no significant difference in noise exposure between the tinnitus and control groups. However, the tinnitus group exhibited significantly larger wave I amplitude, prolonged wave V latency, and extended interpeak interval in MLS responses to chirps at the lowest stimulus rate of 13.8/s. These findings identify unique characteristics of MLS responses to chirps in individuals with tinnitus. We interpret our findings in relation to the ongoing discussion about the neurophysiological mechanisms of tinnitus. Further studies should be conducted to investigate possible etiologies of tinnitus.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 3","pages":"2180-2190"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143710426","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 study evaluated the hearing of 214 service members before and after tactical exercises using boothless audiometers in the field. Training involved weapons systems that generated high levels of impulse noise measured with wearable dosimeters. The impulse waveforms were analyzed to predict the probability of temporary threshold shifts (TTSs) based on various risk criteria. The LAeq,8h predicted TTS events with 64% accuracy (receiver operating characteristic area under the curve = 0.70) on held-out participants using leave-one-out cross-validation. Adding kurtosis improved accuracy to 66% (receiver operating characteristic area under the curve = 0.75). Peak sound level and the Auditory Hazard Assessment Algorithm for Humans model were substantially less accurate predictors of TTS events. A dose-response curve generated using logistic regression indicated a greater likelihood of TTS with increasing cumulative noise exposure. These findings support the use of energy-based auditory risk criteria for impulse noise. However, additional validation data are needed to determine the quantitative risk of short- and long-term hearing damage associated with a given level of impulse noise exposure.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 3","pages":"1926-1937"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143663830","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, neural networks are trained on synthetic data to predict seabed classes from multichannel hydrophone spectrograms of shipping noise. Specifically, ResNet-18 networks are trained on different combinations of synthetic inputs from one, two, four, and eight channels. The trained networks are then applied to measured ship spectrograms from the Seabed Characterization Experiment 2017 (SBCEX 2017) to obtain an effective seabed class for the area. Data preprocessing techniques and ensemble modeling are leveraged to improve performance over previous studies. The results showcase the predictive capability of the trained networks; the seabed predictions from the measured ship spectrograms tend towards two seabed classes that share similarities in the upper few meters of sediment and are consistent with geoacoustic inversion results from SBCEX 2017. This work also demonstrates how ensemble modeling yields a measure of precision and confidence in the predicted results. Furthermore, the impact of using data from multiple hydrophone channels is quantified. While the water sound speed in this experiment was only slightly upward refracting, we anticipate increased advantages of using multiple channels to train neural networks for more varied sound speed profiles.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 3","pages":"2127-2149"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143710422","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 effects of the ellipticity parameters, half-cone angles, dimensionless frequency, and particle position on the acoustic radiation torques of the spherical particle are studied. Simulation results show the axial ART is zero for an arbitrarily positioned viscoelastic PE sphere in a zMB, while for the x or y axis ART, it varies significantly with the particle position and beam parameters. For certain combinations of beam offset and parameters, axial and transverse torques alternate between positive and negative values as the half-cone angle varies. When ka is away from the resonance frequency, the value of the torque is approximately 0.001, which means the torque is small and the particle can be rotated in a uniform angular acceleration. Moreover, ART shows symmetrical about beam center when the offset is less than one wavelength. A finite element model was established to verify the theory and the comparative results agreed with each other except for the values of ART at the first resonant frequency, which is related to the absorption of the particles. The study helps to better understand the potential mechanism of the particle rotation manipulation in a zMB.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"157 3","pages":"1703-1713"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143615785","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}
