Hmmm yeah if it ain't broke.......<br><br>We all know the beep sound. If I heard a shhh sound I'd be thinking what was that? Oops too late.,(reply>), @Mic_Glow That's Darwin at work, baby. If you are actively searching for the sound and somehow manage to miss the fact that is a truck about to back into you I'm sorry but that's just natural selection, you will be missed. RIP,(reply>), @Mic_Glow It doesn't sound like any of those things IRL though. It sounds exclusively like a reversing vehicle. Even if you've never heard it before, you'll know something's up and won't be run over.,(reply>), Is it a broken walkie-talkie? Working air compressor? Sander? Let's peek around the corner and chec... Oh there is a crane tire on my foot.,(reply>), omgcow The reason it had to be changed was PRECISELY because there were too many  avoidable accidents and deaths. If there are five or ten trucks around you, the echo of the beep throws you off as to which one (or more than one) is about to move. Three trucks beeping at the same time really mucks it up, I can tell you from experience. And in cold weather the beeps travel slower and get muffled. The hiss on the other hand hits you like a direct blast. You can’t miss it.,(reply>), KynigosTheWolf If you're in a construction site you DON'T get complacent around beeping of any kind m8. It's always loud enough.
