White noise backup alarm

The white noise backup alarm can be used in any location where a backup alarm is needed, such as construction sites, warehouses, workshops, parking lots, etc. It can provide workers and pedestrians with clearer and more distinct warning sounds in loud noise environments, without producing sharp noises like traditional backup alarms, thereby reducing listener fatigue and discomfort. The white noise backup alarm can also be installed on freight vehicles, excavators, and other heavy machinery to alert pedestrians and other vehicles, ensuring a safe distance between vehicles and pedestrians. In summary, the white noise backup alarm can be widely used in various industries and locations to improve work efficiency and reduce accident risks.
