近日,我院张学良教授团队在国际信号处理领域顶级期刊《IEEE/ACM Transactions on Audio, Speech, and Language Processing》上发表了题为“Neural Multi-Channel and Multi-Microphone Acoustic Echo Cancellation”的学术论文(DOI:10.1109/TASLP.2023.32821...
NASA recorded thousands of hours of audio from the Apollo lunar missions, yet most of us have only been able to hear the highlights.The agency recorded all communications between the astronauts, missi...
Mechanical engineers at Duke University have demonstrated a tiny whirlpool that can concentrate nanoparticles using nothing but sound. The innovation could gather proteins and other biological structu...
Haptics researchers have long known that applying ultrasonic vibrations to a flat, featureless glass plate makes it feel slippery. But they have also long debated why this occurs.Northwestern Engineer...
With more than 800,000 miles of sewer pipes in the United States, wastewater utilities tasked with keeping those pipes clear have their work cut out for them.Now, a small business has developed a quic...
鸟类能学会抽象的语法结构     鸟类  抽象  语法结构       2016/6/29
据物理学家组织网报道,荷兰莱顿大学的科学家在最新一期美国《国家科学院学报》上撰文指出,他们通过对两类鸣禽进行实验发现,至少有两类鸟能学会定义抽象语法结构的规则。在过去50多年间,科学家们已经发现,很多曾被认为人类专属的能力或特征可能也存在某些动物身上。比如,懂得团队其他成员的想法;能使用工具;拥有独特的性格;能感受情感等。而在最新研究中,米歇尔·史毕根斯和卡勒·腾-凯特发现,斑胸草雀和相思鹦鹉这两...
With findings that could have been taken from the pages of a spy novel, researchers at the University of California, Irvine have demonstrated that they can purloin intellectual property by recording a...
In creating what looks to be a simple children’s musical instrument—a xylophone with keys in the shape of zoo animals—computer scientists at Columbia Engineering, Harvard, and MIT have demonstrated th...
科学时报2006年7月17日讯 英国研究人员开发出一种用于预测山崩的新技术,有望在全球范围内减少因山崩造成的大量人员伤亡。拉丁堡大学的科学家们最近研制出了一种声学实时监测系统。这种声学实时监测系统通过收听地质运动的声音来确定山体斜坡的稳定性。该系统通过附带传感器的管子收集山体土壤粒子移动的高频声音,之后将收集到的信息传给电脑,研究人员据此可以分析出山体斜坡的稳定性。声学实时监测系统有望对山体斜坡运...
