Stryker does pretty good with the noises now. After all the racket I made pulling up the carpet and putting new wood flooring in. I'm assuming he got used to the saws and other loud tools. When I was doing the floor he even started to explore the work area and any chance he got he ran off with a tool and a few dozen carpenters pencil's. He's still weary at night but nothing as bad as the truck and trailer over the speed bump. When he hears a plane going over, he'll sit and watch it until he can no longer see it.
