And you live next to it 5/6 days a week 8 hours a day of it constantly going off. At times there are two or three. Oh, weekends too even though they state they don't do construction then. Model neighbors, indeed.

If someone is running heavy equipment or driving and backing up a truck on a construction site the back up beeper, or bell, is to warn the people working around the machines who may be in the path of the machine. Generally the view to the rear is less than optimum and the back up alarm is for the workers, not the machine operator. The alarms are required by OSHA. Heavy equipment operators have their ability to hear yelling or other verbal direction limited because of the noise generated by the machine. That is why there are standard hand signals related to the operation of loaders, cranes etc.
