According to the manufacturer, under normal circumstances, as long as the music of the sprinkler truck is not less than 95 decibels, it is pure music. For convenience, the manufacturer directly set it to the familiar music "Happy Birthday to You" or "Orchid Grass", which not only meets the national standard requirements, but also reduces the cost of multiple tracks.

A piece of pure music that everyone knows is more conducive to reminding road participants? "Happy Birthday to You."

I believe that since the tune of "Happy Birthday to You" has been heard all over the country, no one has not heard this tune. As a fixed tune, whenever this tune is played on the road, pedestrians and vehicles passing by will know that the sprinkler truck is coming and can dodge in time.

This is just like our fire trucks, which are special vehicles. When we hear the specific horn alarm sound they make, we will actively give way. The sprinkler truck is also using "Happy Birthday to You" Let me tell you: I'm here, you have to be careful not to get sprayed by water

Fixed music, large-scale mass production of speakers, reducing costs and production links.

The music of sprinkler trucks is played through special speakers. When purchasing and producing speaker accessories, sprinkler truck manufacturers can reduce the specifications and varieties of purchases if they use fixed tunes. For example, the original Install horns on 10,000 sprinkler trucks. If there are 10,000 horns, the price is 5 yuan (for example, not the actual price). If there are 5,000 horns, the price is 10 yuan. Different tunes can also be considered different specifications and varieties. It turns out that 10,000 speakers only cost 50,000 yuan. If there is one more tune, it will cost 100,000 yuan. The cost will increase significantly?

More music It makes no sense, strengthening the water spray cleaning function is the key.

The sprinkler truck is not a singing station or a music player. It plays warning music when it passes by. It is more to remind pedestrians and vehicles to pay attention. It doesn’t matter what kind of music it is. Its more critical function is to spray water and clean the road surface, so what manufacturers need to strengthen is the research and development of water spraying, cleaning, water storage capabilities, etc. Under normal circumstances, they rarely spend time to study what kind of music is good, and it is unnecessary.
