Pulsed ultrasound can produce chronotropic and inotropic effects on the heart with potential therapeutic applications. Fourteen 3-month-old female rats were exposed transthoracically to 3.5-MHz 2.0-MPa peak rarefactional pressure amplitude ...
Dark tone quality and vocal tract shaping in soprano song production: Insights from real-time MRI [0.03%]
关于女高音歌唱时的暗色调质量和声道塑形的实时MRI洞察

Tone quality termed "dark" is an aesthetically important property of Western classical voice performance and has been associated with lowered formant frequencies, lowered larynx, and widened pharynx. The present study uses real-time magneti...
The influence of flow model selection on finite element model parameter estimation using Bayesian inference [0.03%]
基于贝叶斯推理的流道模型选择对有限元模型参数估计的影响研究

Learning to perceive non-native speech sounds is difficult for adults. One method to improve perception of non-native contrasts is through a distributional learning paradigm. Three groups of native-English listeners completed a perceptual a...
Intelligibility of first-language (L1) and second-language (L2) speech by switched-dominance Spanish-English bilinguals [0.03%]
手语互换支配的西班牙语-英语双语者的口语易懂性研究

Michael Blasingame
Recordings of Spanish and English sentences by switched-dominance bilingual (SDB) Spanish (i.e., L2-dominant Spanish-English bilinguals) and by L1-dominant Spanish and English controls were presented to L1-dominant Spanish and English liste...
Measurement and simulation of steered acoustic fields generated by a multielement array for therapeutic ultrasound [0.03%]
治疗用超声波多元素阵列生成导向声场的测量与仿真研究
Eleanor Martin,Morgan Roberts,Bradley Treeby
Eleanor Martin
Modelling of fields generated by therapeutic ultrasound arrays can be prone to errors arising from differences from nominal transducer parameters, and variations in relative outputs of array elements when driven under different conditions, ...
Interaction between epilaryngeal and laryngeal adjustments in regulating vocal fold contact pressure [0.03%]
声门上和声门前后的调节机制在调节声带接触压力方面的相互作用
Zhaoyan Zhang
Zhaoyan Zhang
This study investigates the peak vocal fold contact pressure at different conditions of epilaryngeal narrowing and laryngeal adjustments. The results show that for a given subglottal pressure, the peak vocal fold contact pressure may increa...
Interactions among talker sex, masker number, and masker intelligibility in speech-on-speech recognition [0.03%]
讲话人性别、掩蔽声数量和可懂度在言语掩蔽中的交互作用
Mathew Thomas,John J Galvin rd,Qian-Jie Fu
Mathew Thomas
In competing speech, recognition of target speech may be limited by the number and characteristics of maskers, which produce energetic, envelope, and/or informational masking. In this study, speech recognition thresholds (SRTs) were measure...
Feasibility of remote assessment of the binaural intelligibility level difference in school-age children [0.03%]
学龄儿童双耳言语识别差的远程评估的可行性研究
Gabrielle R Merchant,Claire Dorey,Heather L Porter et al.
Gabrielle R Merchant et al.
This work evaluated the feasibility and reliability of remotely assessing masked speech recognition and the binaural intelligibility level difference (BILD) in children. Participants were 28 children (6-17 years) and 11 adults (22-45 years)...
Extended low-frequency phase of the distortion-product otoacoustic emission in human newborns [0.03%]
人类新生儿畸变产物耳声发射的延长低频相位
Anders T Christensen,Christopher A Shera,Carolina Abdala
Anders T Christensen
At constant f 2 / f 1 ratios, the phase of the nonlinear distortion component of the 2 f 1 - f 2 distortion-product otoacoustic emission (DPOAE) has a steep low-frequency segment and a flat high-frequency segment in adults and newborns...
