Acoustic Signal Receiving Device for Effective Infrastructure Monitoring

Purpose. The product is designed for video surveillance of infrastructure objects, remote non-contact multi-channel reception of vibroacoustic signals formed by these objects in the sound frequency range with the possibility of visualising the acoustic field in real time. Design features. The product is made in the form of a monoblock and represents a hardware-software complex including a video camera, a microphone array and a signal processing module, which provides the possibility of forming a narrow acoustic radiation pattern and controlling the position of its maximum on the video image. Advantages. The vibroacoustic field is determined by remote method, without installation of contact sensors on the controlled object.
