I hear "beep,beep,beep...." every school morning from the minibus collecting neighbours children,I used to hear "Warning! Large Vehicle reversing" every time a supermarket delivery van was here,more recently changed to "Squawk...Large Vehicle reversing...Squawk....etc" which I presumed to be due to the vehicles reversing announcement system getting damaged by it reversing into something solid,but might have been a combination of white noise &amp; voice announcement. Either way,they both are bloody annoying sounds waking me up.
