Our signature acoustic threat detector, the Acoem Acoustic Threat Detection (ATD) system deploys military grade threat detection on the ground in a variety of civilian contexts, helping law enforcement and security staff make faster, more informed tactical response decisions to emergency situations.
Aug 4, 2023 · Acoustic sensors are devices designed to detect and measure sound waves or acoustic signals in the surrounding environment. These sensors convert sound waves into electrical signals, which can then be analyzed, processed, and used for various applications.
Aug 28, 2020 · A system for acoustic detection and tracking of small objects in movement, such as UAVs or terrestrial robots, using acoustic cameras is introduced in . In their work, the authors deal with the problem of tracking drones in outdoor scenes, scanned by a lidar sensor placed on the ground level.
Jul 19, 2023 · Herein, an acoustic and optical sensor-fusion-based system-termed multimodal unmanned aerial vehicle 3D trajectory exposure system (MUTES) is presented to detect and track drone targets. MUTES combines multiple sensor modules including microphone array, camera, and lidar.
In this study, an acoustic detection system based on resonant-enhanced acquisition is proposed. By utilizing a horn-shaped acoustic resonator with multiple resonant frequencies, the proposed system can realize long-distance acoustic sensing with high sensitivity in both the audible and ultrasonic ranges.
Nov 9, 2020 · First we describe different methodologies and techniques of using acoustic signals for sensing including Time-of-Arrival (ToA), Frequency Modulated Continuous Wave (FMCW), Time-Difference-of-Arrival (TDoA), and Channel Impulse Response (CIR).
Mar 6, 2023 · This article presents an automatic acoustic system that can detect, localize, and classify acoustic impulse events, such as gunshots. The presented system is based on standalone units, which continuously monitor its surrounding.
This paper presents a system for acoustic detection, which can detect localize and classify acoustic events such as gunshots. Tested firearms are 9 mm short gun, 6.35 mm short gun, .22 short gun, and .22 rifle gun with various subsonic and supersonic ammunition.
Stevens Institute of Technology has developed and built the Drone Acoustic Detection System (DADS) that can detect, track and classify UAVs based on the propeller noise. The system consists of three or more microphone nodes.
Acoem’s revolutionary Acoustic Threat Detection (ATD) is the most advanced gunshot detection technology in the world, enabling better situational awareness.
