Regularization trades inversion accuracy against loudspeaker dynamic-range demands

Evidence

If β is selected to be very small, sharp peaks will result in the time-domain inverse filters, which may exceed the dynamic range of the loudspeakers. If β is larger, the impulse response of the inverse filter will have a longer duration in time, which is less demanding on the loudspeakers, but the price paid is that the inversion is less accurate (Kirkeby et al., 1998). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1944
