Microphone arrays add an extra dimension to sensory information from Wireless Sensor
Networks by determining the direction of the sound instead of only its intensity. Microphone …

Sound source localization (SSL) has been widely applied in industrial and civil fields. And
with the development of wearable devices and the Internet of Things (IoT), it is attractive to …

Many applications rely on MEMS microphone arrays for locating sound sources prior to their
execution. Those applications not only are executed under real‐time constraints but also are …

High performance and extreme energy efficiency are strong requirements for a fast-growing
number of edge-node Internet of Things (IoT) applications. While traditional Ultra-Low …

Wireless acuusuc sensor networks (wasns) are a promising technology for performing
acoustic surveillance because of their flexibility and low cost. However, their …

Least Squares (LS) triangulation is one of the most used methods for AOA (Angle of Arrival)
localization. However, the localization results can be affected by bearing outliers. So it is …

This paper presents an omnidirectional ultra low-power MEMS microphone array for use in
low-power distributed wireless sensor networks. The microphone array is used for …

Physical defects in capacitive MEMS devices can change the nominal device capacitance
by a few femtofarads. Detecting such small variations is challenging particularly in the …

Human knows the source of the sound when receiving the sound though ears, because the
difference of time is received by left and right ears. The proposed system demonstrates how …

The current Microelectromechanical Systems (MEMS) technology enables the deployment
of relatively low‐cost wireless sensor networks composed of MEMS microphone arrays for …
