The proposed scheme addresses the noise environment inside the helmet to achieve perceivable noise attenuation. It also incorporates algorithms such as energy based detectors to control the operation of ANC system and variable step-size to increase the performance of ANC, to make the system robust. The paper highlights the real-time algorithm development on a DSP processor to meet the real-time resource constraints. The developed ANC system is evaluated in the laboratory for a typical fighter aircraft noise and the results when compared with the performance of existing system, found to be quite promising.

This method proves to be suitable for both interconnected as well as radial distribution systems. The main feature of this technique is that the optimal bus in which the D-STATCOM is to be placed can be found just by knowing the system parameters, without the need of practical experimentation causing transient conditions. The system is modeled in Matlab/Simulink environment and case studies are performed on it. ANN is trained offline and optimal bus is identified using the training performance. The implementation on a radial feeder situated in Hunsinkere, Hassan illustrate the effectiveness of the proposed technique.

The heart of VOS is a Voice Activity Detection (VAD) algorithm. This paper explores the evolution of a reliable, robust VAD scheme for VOS application in aircraft by comparing real-time robust VAD schemes, which are based on energy-based detectors, fuzzy logic and ANN. MATLAB, is used as the simulation platform and actual fighter aircraft cockpit noise record is used for evaluation of the algorithms.
