In B-mode medical ultrasound, a ringdown artifact is a vertical, linear artifact composed of horizontal bands. In this study, in vitro ringdown artifact models are investigated. Frequency domain spectral analysis of the ringdown artifact sh...
Sentence recognition and enhancement in noise: Effects of speech muffling, signal-to-noise ratio, and formant enhancement [0.03%]
语音模糊、信噪比和共振峰增强对句子理解及改善的影响

Marine sediment sound speed profiles in the upper ten meters are generally assumed to be constant with time. Models predict that substantive changes occur because of thermal conduction from seasonally varying bottom water temperature. Howev...
Electroacoustic single-cell spectroscopy for morphological differentiation of red blood cells: An in silico feasibility study [0.03%]
基于声电单细胞分光谱技术的红细胞形态分类的仿真研究
Anuj Kaushik,Mayank Kumar,Rochish Thaokar et al.
Anuj Kaushik et al.
A computational electroacoustic framework is presented for morphology-dependent characterization of single red blood cells. Electric fields obtained via finite-element modeling were converted into initial electroacoustic pressure sources an...
Evaluating peripheral neural processing through spectral analysis of auditory brainstem responses [0.03%]
听性脑干反应的频谱分析在周围神经处理评估中的应用

There has been renewed interest in using auditory brainstem responses (ABR) to examine peripheral auditory processing. Spectral-domain ABR analysis offers ease of objective quantification of neural responses and may highlight different info...
Coarticulation vs Phonologization: Evidence from Southern Italo-Romance [0.03%]
南意大利罗曼语的共发音与音系化：来自南方意第绪罗曼语的证据
Pia Greca,Francesco Burroni,Jonathan Harrington
Pia Greca
This study compares the variety of Italian spoken in Campania and the Italo-Romance variety of Mormanno (Calabria) to investigate the acoustic differences between phonetic vowel-to-vowel coarticulation and phonologized metaphony. The study ...
A multi-task neural network for source localization in shallow-water environment with depth classification [0.03%]
一种用于浅海水下声源定位并分类水深的多任务神经网络方法研究

Limited high-quality training data can cause overfitting and weak generalization in deep-learning-based source localization, leading to degraded performance in realistic environments. In this study, a multi-task neural network with a depth-...
Frequency modulation detection in Mandarin Chinese-speaking amusics across modulation rate, carrier frequency, and stimulus duration [0.03%]
汉语阿莫西林患者的频率调制检测作用不受载波频率和刺激时间的影响
Mingshuang Li,Yun Nan,Wei Tang et al.
Mingshuang Li et al.
Frequency modulation (FM) detection was examined in Mandarin Chinese-speaking listeners with congenital amusia, including pure amusics and tone agnosics (without and with lexical tone deficits, respectively). Thresholds were measured across...
Spectral weighting of interaural time differences near the low-frequency dominant region in young and middle-aged adults [0.03%]
年轻及中年受试者低频占优势区域附近的双耳时差谱功率分布权重研究
G Christopher Stecker,Brittany T Williams,Niklas Isserstedt et al.
G Christopher Stecker et al.
Spectral weighting functions (SWF) were measured for lateralization of complex tones via interaural time difference (ITD), with higher frequency resolution (1/4-octave) compared to prior studies. SWFs revealed a region of dominant ITD weigh...
