In what is now considered to be a founding work in the field of sound system equalization,Rudmose [13] applied emerging equalization methods to the Dallas Love Field Airport. Advancesin the theory of acoustic feedback led to the development of an equalization system with verynarrow notch filters that could be manually tuned to the frequency at which feedback occurs [14,15].Expanding and extending this work, Conner established the theory and methodology of soundsystem equalization [16].
