You can not NOT hear it, when these kind of city trucks pass by. They cleanse the city, and ensure the Autumn leaves are gone. When I wanted to enter our Antwerp office yesterday, I noticed the heavy noise of the suctioning of dust and leaves of this truck. I think it is a diesel truck, but I could not hear the engine of the truck. I only heard the enormous sound of the suctioning. So, changing the engine would not even be the biggest factor in noise reduction – it would clean the air though. And it’s not only these big machines that are noisy. It surprises me that even a home vacuum cleaner is a very noisy device, and that device is 100% electric.
Suctioning renders cities clean but they also make them very noisy
