A VOICING PROBLEM WITH A CATERPILLAR

We have a noice problem with a CAT in a company truck, which asks us to go down the noise level below 80 db and of course, the most economically feasible.

We have done several tests, from the exhaust to the bottom of the counterweight, soundproof siding with tapestry, both the environment of the suction, as under the hood, which is already isolated from the factory, also the roof internally, the inner of the board of the pedals and the upper radiator cap, knowing that the back carries a driver's cabin door with plastic zippers, totally off the hook.

After doing these tests, we left at about 82-83 db, given that the noise level of the factory is prowling the 77-78 db.

With these data, and without thinking of a cabin fitted with tight seals, COULD YOU tell me any other solution to get down them below 80 decibels ..???
