  4. 13. Physical Structures for Signal Separation

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Albin Nordsjö; [2016]
    Keywords : Signal separation; physical; parabolic reflector; reflector; signal processing; Technology and Engineering;

    Abstract : This master’s thesis studies the use of physical structures for signal source separation. A parabolic reflector was used to alter the directional properties of one microphone in a two-microphone array. A method to estimate the mixing channels from measured data is presented, as well as a method to find the optimal separating channels. READ MORE

  5. 14. Detection of Emergency Signal in Hearing Aids using Neural Networks

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Vamshi Krishna Lakum; Arshini Gubbala; [2014]
    Keywords : Microphone Array; Fractional Delay; Beam Former; Adaptive Algorithms; Neural Networks;

    Abstract : ABSTRACT The detection of an emergency signal can be estimated by the cancellation of surrounding noise and achieving the desired signal in order to alert the automobilist. The aim of the thesis is to detect the emergency signal arriving nearer to the automobilist carrying hearing aids. READ MORE
