While walking down 6th St., Kentuckiana Sounds curator Aaron Rosenblum found himself enveloped in a droning, omnipresent hum reverberating among the buildings on the block.

Musician and student Chris Leidner lives in a noisy neighborhood. His Old Louisville apartment is above a narrow street where the sounds of cars and motorcycles ricochet and rattle his windows.

Flash Dads is a JCPS program that brings men from the community into JCPS schools to serve as positive role models and welcome students. The volunteers come from throughout the community, and bring their own style to the early morning surprise greeting.

To the average driver seeing it from their commute, The Kentucky Derby Festival Great Balloon Race might seems like a peaceful, placid affair. But as anyone who's ever been to the Balloon Glow or the liftoff of the Great Balloon Race knows, it takes a lot of generator-powered fans and roaring gas jets to get the colorful balloons off the ground.

The commercial developments around Outer Loop may not seem much like nature sanctuaries, but Kentuckiana Sounds curator Aaron Rosenblum found one hidden water management feature full of busy nocturnal creatures.

The sounds of a college football game can travel pretty far. So can the sounds of a freight train. Drawn to the periphery of Cardinal Stadium by the Clemson at UofL game in 2015, Kentuckiana Sounds curator Aaron Rosenblum found that the adjacent railroad tracks were as noisy as the game itself.

New sounds arrive with the changing seasons — migrating birds in the spring, cicadas in the summer, and leaf blowers in the fall.
