Attributing omnidirectional sound levels to a specific source in the ocean can be challenging when there are multiple competing sources of sound such as boats, or biological activity. Here, we present a method to directionally filter acoust...
Bayesian matched-field inversion for shear and compressional geoacoustic profiles at the New England Mud Patcha) [0.03%]

This Letter estimates shear and compressional seabed geoacoustic profiles at the New England Mud Patch through trans-dimensional Bayesian inversion of matched-field acoustic data over a 20-2000 Hz bandwidth. Results indicate low shear-wave ...
Enhancing speech intelligibility in optical microphone systems through physics-informed data augmentation [0.03%]
基于物理信息的数据增强在光学麦克风系统中的应用以提升语音清晰度
Jia-Wei Chen,Jia-Hui Li,Yi-Hao Jiang et al.
Jia-Wei Chen et al.
Laser doppler vibrometers (LDVs) facilitate noncontact speech acquisition; however, they are prone to material-dependent spectral distortions and speckle noise, which degrade intelligibility in noisy environments. This study proposes a data...
Leveraging sound speed dynamics and generative deep learning for ray-based ocean acoustic tomography [0.03%]
利用声速动态和生成深度学习进行基于射线的海洋声层析成像

Priyabrata Saha et al.
A generative deep learning framework is introduced for ray-based ocean acoustic tomography (OAT), an inverse problem for estimating sound speed profiles (SSP) based on arrival-times measurements between multiple acoustic transducers, which ...

The confinement of coherent phonons in acoustic cavities can lead to ultrahigh-frequency resonators and may tap into the quantum nature of phonons. Their practicality is linked to the coherent phonon lifetime or the characteristic time scal...
Detection ranges of blue whale vocalizations from a glider-based hydrophone [0.03%]
滑翔机基水下麦克风检测蓝鲸叫声的范围
Laura Gutiérrez,Susannah Buchan,Kathleen M Stafford et al.
Laura Gutiérrez et al.
This study investigated the detection range (DR) of blue whale (Balaenoptera musculus sp.) vocalizations (SEP2 and D-calls) in Chilean Patagonia using data collected from ocean glider-based hydrophones. DRs were determined by calculating th...
Variation in the production of nasal coarticulation by speaker age and speech style [0.03%]
发音人年龄和说话方式在鼻音协同发音中的变化研究

Georgia Zellou
This study investigates apparent-time variation in the production of anticipatory nasal coarticulation in California English. Productions of consonant-vowel-nasal words in clear vs casual speech by 58 speakers aged 18-58 (grouped into three...
Effects of age, stimulus degradation, and sentence context on auditory temporal processing [0.03%]
年龄、刺激退化和句子语境对听觉时间处理的影响

Zilong Xie
This study examined how age, stimulus degradation, and sentence context affect sensitivity to speech temporal cues. Adults aged 20-72 with self-reported normal hearing completed a phonemic categorization task using unprocessed and 8-channel...
Effects of spatial asymmetry and voice-gender differences between talkers on spatial release from masking in normal-hearing listeners [0.03%]
空间不对称性和说话者性别差异对正常听力人群的空间释放效应的影响
Yonghee Oh,Josephine Kinder,Phillip Friggle et al.
Yonghee Oh et al.
This study investigated how a listener's spatial release from masking (SRM) performance is affected by spatial asymmetry and voice-gender differences between talkers in multi-talker listening situations. The amounts of SRM were measured wit...
A method of reference phase velocity selecting for bearing estimation with a horizontal line array in shallow water [0.03%]
浅海水平线列阵中参考相速度的选择方法
Dai Liu,Feilong Zhu,Yanjun Zhang et al.
Dai Liu et al.
In shallow water environments, choosing an appropriate reference phase velocity for direction-of-arrival estimation with a beamformed underwater horizontal line array is very important. The direction of the maximum beamformer output power w...
