Using pressure gradient-based methodology, a compact 33-cm, four-element, tetrahedron-shaped hydrophone array is demonstrated to emulate the low-frequency direction of arrival (DOA) finding performance of a vector sensor. Towed from an auto...
Including two-dimensional pressure-focusing in transmission-line cochlear models [0.03%]

Transmission-line models are the simplest physics-based cochlear models that include an explicit representation of the traveling wave, which plays an important role for encoding complex sounds in the auditory periphery. Despite their many a...
Spatiotemporal tongue kinematics from ultrasound imaging: Articulatory divergence in Mandarin apical vowels [0.03%]
基于超声影像的汉语舌尖元音吐舌时空变化及发音差异研究

Mandarin apical vowels [ɹ'] and [ɻ'] have resisted articulatory classification: are they vocalized prolongations of the preceding sibilant or independent vowel targets? Using ultrasound imaging and generalized additive mixed models with s...

While auditory and visual cues jointly support vowel perception, the role of visual information alone in vowel identification remains understudied. This study examines how Taiwan Mandarin speakers identify rounded vowels using visual-only i...
Perception of English vowels across regional accents by Catalan-Spanish bilinguals [0.03%]
加泰罗尼亚-西班牙双语者对不同口音英语元音的感知研究

Successive room impulse response (RIR) measurements exhibit subtle variations, mainly caused by atmospheric fluctuations due to spatiotemporal air-temperature differences. This work extends the image source method by incorporating temperatu...
Acoustic field extrapolation in shallow water using Gaussian process with Normal-Mode-Based Kernel [0.03%]
基于正交模式的高斯过程在浅海声场外推中的应用研究
An Yang,Peng Xiao,Zhengyu Hou et al.
An Yang et al.
In ocean acoustics, vertical array depth shifts caused by currents lead to missing shallow-water acoustic field data. This study applies a Gaussian process (GP) regression framework with a Normal-Mode-Based Kernel to address the extrapolati...
Quasi-psychoacoustic metrics for sound quality analysis of low-resolution data [0.03%]
基于低分辨率数据的主观音质评价的准心理声学客观指标
Michael J B Lotinga,Carlos Ramos-Romero,Marc C Green et al.
Michael J B Lotinga et al.
Psychoacoustic metrics offer the means to analyse sound qualities using sophisticated models of human perception. A substantial drawback is the need for high-resolution acoustic data as input. Quasi-psychoacoustic metrics are proposed to ad...
Incomplete compensation without further adaptation: A large-sample acoustic analysis of bite block speech in masking noise [0.03%]
无进一步适应情况下的不完全补偿：对掩蔽噪声下咬块语音的大样本声学分析
Timothy K Murphy,Hung-Shao Cheng,Caroline A Niziolek et al.
Timothy K Murphy et al.
The speech system maintains intelligibility even when articulatory movements are restricted. Researchers often study this compensatory mechanism using a bite block to constrain jaw movement. While early reports indicated that speakers fully...
