Estimation of binary time-frequency masks from ambient noise
JL Romero, M Speckbacher - SIAM Journal on Mathematical Analysis, 2024 - SIAM
We investigate the retrieval of a binary time-frequency mask from a few observations of
filtered white ambient noise. Confirming household wisdom in acoustic modeling, we show
that this is possible by inspecting the average spectrogram of ambient noise. Specifically, we
show that the lower quantile of the average of masked spectrograms is enough to identify a
rather general mask with confidence at least, up to shape details concentrated near the
boundary of. As an application, the expected measure of the estimation error is dominated …
