چکیده
This chapter describes the design and implementation of a Smart Acoustic Sensor Array (SASA) System consists of a 52 microphone MEMS array embedded in an FPGA (Field Programmable Gate Array) platform with real-time data acquisition, signal processing, and network communication capabilities. The SASA system is evaluated using several case studies in order to demonstrate the versatility and scalability of the sensor array platform for real-time sound analysis applications. These case studies include sound mapping and source localization.

متن کاملCompact and Efficient Active Vibro-acoustic Control of a Smart Plate Structure
An effective wide band active control law through one kind of the Dynamic Vibration Absorber (DVA) is proposed and studied in this paper. With the help of mechanical impedance method, active DVA control law is formulated based on the passive mechanical model. The electrical DVA can generate multi-mode active damping to the structure. The host structure is an aluminum plate and acceleration sign...
متن کاملPhysical audio digital filters
We propose an approach to insert physical objects in audio digital signal processing chains, filtering the sound with the acoustic impulse response of any solid measured in real-time. We model physical objects as a linear time-invariant system, which is used as an audio filter. By interacting with the object or with the measuring hardware we can dynamically modify the characteristics of the fil...

متن کاملFeasibility Study of Real-time and Automated Monitoring of Iranian Rivers using 50-kHz Fluvial Acoustic Tomography System
Acoustic Tomography (AT) technique is an innovative method for real-time river monitoring. In this study, not only the accuracy of flow velocity measurement using 50 kHz AT system which is appropriate for narrow rivers (most Iranian rivers) is evaluated, but also its performance is compared with 30 kHz one which is used in wide rivers. The comparison results showed that the velocity resolutions...
