Why Do Water Sprinkler Trucks Play Music?

[VonRosalie]

Water sprinkler trucks play music for the following reasons: 1. The primary purpose is to serve as an audible warning. Pedestrians and vehicles can hear the music from a distance, allowing them to move aside promptly. 2. The music played by sprinkler trucks is typically cheerful and catchy (for example, in Linyi region, the Yimeng Mountain folk tune is used). These melodies can uplift people's moods and make them more receptive. Even if water accidentally sprays on passersby, the music helps mitigate irritation by acting as an emotional buffer and soothing mechanism. Additional information: Water sprinkler trucks, also known as green sprinkler vehicles or garden sprinkler trucks, are used for seedling irrigation, urban greening, factory dust suppression, firefighting water supply, and road cleaning. Their working principle involves utilizing the vehicle's engine power through a power take-off to drive the onboard water pump, which either draws water into the tank or distributes stored water through pipelines to various sprinkler heads for different functions.
