Devices and contraptions that make sound effects are among my favorite things, ranking well above cream-colored ponies, bright copper kettles, and possibly even whiskers on kittens.
So I was delighted to see this little video about how sound effects have been made over the years (though I think they skip over the valuable contributions voice-over artists have been able to do with their own voices: think Mel Blanc’s sad Maxwell sputtering on the Jack Benny Show for just one example).
Enjoy!
