The main problem in identifying the acoustic feedback path model is the correlation between the near-end signal and the loudspeaker signal caused by the closed signal loop, in particular when the near-end signal is spectrally colored as is the case for a speech signal.
As was the case for voiced speech, it is possible to gain approximately 15 dB in SNR by increasing the filter length from 20 to 110.
As a test case for free speech, he cites the extreme case of the Westboro Baptist Church; and he notes (as a recent Erasmus posting did) that purist libertarians are prepared to defend both the Westboro bigots and even the plan of a neo-Nazi group to stage an event in a town in Illinois where many holocaust survivors live.
