PHYSICAL FIELDS OF CIRCULAR CYLINDRICAL PIEZOCERAMIC RECEIVER IN PRESENCE OF A FLAT ACOUSTIC SOFT SCREEN by A. V. Derepa, A. G. Leiko, O. N. Pozdniakova

“…System in the form of a circular cylindrical piezoceramic transducer near a flat acoustic screen was analyzed. The aim of the work was to solve the problem of receiving plane sound waves by «cylindrical piezoceramic transducer – flat acoustically soft screen» system.Considered system was characterized by a violation of the radial symmetry of the radiation load of the transducer while maintaining the radial symmetry of the electric load. …”

A study on the acoustic propagation characteristics of circular expanding ducts using the finite element method by Wenyu Guan, Zhongying Xiong, Huan Xia

“…A circular expanding duct features an increasing cross-sectional area that tends to excite higher-order modes at low frequencies, thereby affecting the performance of acoustic devices. Studying the acoustic propagation characteristics of circularly expanding ducts is thus crucial for optimal design and noise control. …”

Experimental Study of the Creep Disturbance Effect and Acoustic Emission Characteristics of Mudstone with Different Moisture Contents by Yongjiang Yu, Pengbo Wang, Shipeng Zhang, Jingjing Liu

“…Moreover, as the moisture content increases, the type of mudstone creep disturbance failure gradually changes from accelerated creep failure to disturbance failure. By analyzing the acoustic emission (AE) characteristics of the mudstone creep disturbance tests, it was found that the increase in the moisture content greatly weakens the AE count and the accumulated energy. …”
