Hybrid active noise barrier with sound masking
In this paper, a hybrid active noise barrier (ANB) with sound masking capability is considered. To protect the speech privacy, several sound masking techniques have been developed. However, these sound masking techniques based on the superposition of the masker and original sound will lead to increase in the loudness of the sound after masking. Against this problem, this paper proposes a soundp...
متن کاملA Review of Active Noise Control Algorithms towards a User-implementable Aftermarket Anc System
The past 30 years have shown a steady uptick in the application of of Active Noise Control (ANC) technology to the practical problem of noise pollution in various fields including audio, transportation, medicine, appliances, industrial and more. Part of this success stems from the exponential increase in the computational power of modern microprocessors and their corresponding decrease in size,...
متن کاملNoise Reduction in Speech Processing Using Improved Active Noise Control (anc) Technique
An improved feed forward adaptive Active Noise Control (ANC) scheme is proposed by using Voice Activity Detector (VAD) and wiener filtering method. The ‘speech-plus-noise’ periods and ‘noise-only’ periods are separated using VAD and the unwanted noise is removed by adaptive filtering method. By using Speech Distortion WeightedMultichannel Wiener Filtering (SDW-MWF) algorithm the noise periods w...
متن کاملUser and Noise Adaptive Dialogue Management Using Hybrid System Actions
In recent years reinforcement-learning-based approaches have been widely used for management policy optimization in spoken dialogue systems (SDS). A dialogue management policy is a mapping from dialogue states to system actions, i.e. given the state of the dialogue the dialogue policy determines the next action to be performed by the dialogue manager. So-far policy optimization primarily focuse...
متن کاملPerformance Evaluation of an ANC-based Hybrid Algorithm for Multi-target Wideband Active Sonar Echolocation System
This paper evaluates performances of an adaptive noise cancelling (ANC) based target detection algorithm on a set of real test data supported by the Defense Evaluation Research Agency (DERA UK) for multi-target wideband active sonar echolocation system. The hybrid algorithm proposed is a combination of an adaptive ANC neuro-fuzzy scheme in the first instance and followed by an iterative optimum...
