An electronic device includes a classifier circuit, a ranking circuit, and a data generator circuit. The classifier circuit is configured to determine, based on first data indicating samples of sounds detected at a plurality of geographic locations, a plurality of acoustic event classifications associated with the plurality of geographic locations. The ranking circuit is configured to determine a plurality of index scores associated with the plurality of geographic locations by ranking each of the plurality of geographic locations based on the plurality of acoustic event classifications. The data generator circuit is configured to generate, based on the plurality of index scores, second data indicating a geographic map corresponding to the plurality of geographic locations. The second data further indicates the plurality of index scores and a prompt to enable a search for a particular type of acoustic event.
