Do not turn your speaker volume up to high! This is Federal Signal Thunderbolt 1000T in Louisville, Ky. at Westport Middle school sounding in alert (steady) for the second Tuesday of the month at noon monthly test. This siren is part of Jefforson County's siren system. This is a special video with a two camera shot, the first part of the video is with audio from the main camera, the second part is with audio from underneath the siren and the third is with both combined. At the end of each part I boosted the volume up so you can hear the chopper wind down and any other sirens in the background, the only on I can hear is a Thunderbolt. I will also be uploading the orginal videos for the main shot and underneath for those who are interested as well as an audio recording that I took with my iPod 4th Gen. Thanks for watching!
