  1. 11. Acoustic feedback suppression in audio mixer for PA applications

    University essay from Umeå universitet/Institutionen för fysik

    Author : Mattias Ekström; [2017]
    Keywords : Digital signal processing; feedback suppression;

    Abstract : When a speaker is addressing an audience, a PA system consisting of a microphone and a loudspeaker is often used. If the microphone picks up too much of the loudspeaker energy, acoustic feedback in the form of an unwanted characteristic howling can occur. READ MORE
