1. An ear-wearable device, comprising:
a persistent memory storing a plurality of neural network data objects each defining a respective neural network;
a classifier that classifies an ambient environment of a digitized sound signal into one of a plurality of classifications;
a neural network processor that, based on the classification, selects one of the neural network data objects to enhance the digitized sound signal; and
a second signal processing module that forms an analog signal based on the enhanced digitized sound signal, the analog signal being reproduced via a receiver of the ear-wearable device.
