changes after testing
After testing, we realized that the elastic string would be too short to fit around the capsule. So, we changed the length of the elastic string from 8 inches to 12 inches so that it could be looped through a zipper.
summary
During the testing process, we found that our device could be heard 60 meters away and also could be activated in 2.92 seconds. We believe that this testing proved our product to be effective, because the device can be heard from relatively far away and it can be activated quickly in an emergency situation. If we had more time after our testing, we would have liked to have made more changes to our design. We wanted to make the siren to be louder and require a two-step initiation. We also would have liked to make the switch larger so it could be activated more easily.
