It's been adapted to radio a few times - on Dimension X in 1950 as a double-feature with "There Will Come Soft Rains" (listen to it at archive.org here), on Escape in 1953 (listen to it at archive.org here) and on Suspense in 1955 (listen to it at archive.org here). They're all very good, but I feel the Dimension X version hits the climax with the most force.
In 1953, Al Feldstein and Jack Kamen adapted the tale for EC Comics and did a pretty great job. In 1992 it was adapted for television's Ray Bradbury Theater, but I can't really recommend this version. The acting is not only inferior compared to the radio versions, it's just not very good, full stop. The terrifying climax is particularly underwhelming, considering the potency of the radio adaptations.
More horror from Bradbury tomorrow!
