Visual and Acoustical Social Displays by the Grasshopper Arphia Conspersa (Orthoptera: Acrididae) by Robert B. Willey, Ruth L. Willey

“…Many species of the Oedipodinae (band-wing grasshoppers) exhibit strikingly diverse social interactions invoking visual and acoustical communication between the sexes and between individuals of the same sex (Otte, 1968, 1969).…”

Experimental Study on Shear Behavior and Acoustic Emission Characteristics of Nonpersistent Joints by Yujing Jiang, Yongqiang Chen, Xianzhen Cheng, Hengjie Luan, Sunhao Zhang, Qizheng Zhao, Wei Han

“…The shear strength of the specimens is affected not only by the crack length but also by the crack distribution. The acoustic emission (AE) count peak occurs when the shear stress drops sharply and has an inverse “S”-type variation trend with the increase of the crack length. …”

A State-Space Modeling Approach for Active Structural Acoustic Control by Leopoldo P.R. de Oliveira, Paulo S. Varoto, Paul Sas, Wim Desmet

“…A promising approach to cope with this challenge is the use of active structural-acoustic control. Usually, the low frequency noise is transmitted into the vehicle's cabin through structural paths, which raises the necessity of dealing with vibro-acoustic models. …”

Multiple underwater target positioning with optimally placed acoustic surface sensor networks by David Moreno-Salinas, Antonio Manuel Pascoal, Joaquín Aranda

“…For reasons that have to do with the unavailability of Global Positioning System underwater, cost reduction, and simplicity of operation, there is currently a surge of interest in the development of range-based multiple target localization systems that rely on the computation of the distances between the targets and a number of sensor nodes deployed at the ocean surface, equipped with acoustic range measuring devices. In the case of a single target, there is a wealth of literature on the problem of optimal acoustic sensor placement to maximize the information available for target localization using trilateration methods. …”
