How can a Garbage Truck Tricycle be soundproofed?

In order to provide a good operating environment for the driver in the cab of a tricycle, some sound insulation measures are usually taken. However, these measures are not very effective sometimes. Is there any good way to improve its sound insulation effect?

1. Carpets can be laid for Tricycle Motorcycle to isolate part of the noise transmitted from the bottom plate and help the Tricycle Motorcycle improve its sound insulation effect.
2. Enhance the sealing of the Garbage Truck Tricycle. Check whether the sealing system structure design is reasonable for the poor sealing of the doors and windows, whether the sealing strip assembly is biased, and strengthen the use of sealing materials for the wiring harness holes and the joystick holes. In addition, it is necessary to ensure that the assembly and welding accuracy of the sheet metal parts meet the requirements, and the use of sealing coating glue should be in place.
3. The low-frequency sound insulation performance of the panel is related to the stiffness and damping of the material. Therefore, the thickness of the doors, windows and glass of the Garbage Truck Tricycle can be appropriately increased under the requirements of the vehicle body weight control. The thickness of the wall panels at the key positions of the vehicle body can effectively improve the overall sound insulation performance of the vehicle body.
