Abstract

An operator cab for a work vehicle includes: a cab enclosure including a roof an operator chair disposed in the cab enclosure; at least one layer of noise-deadening material coupled to the roof; and a headliner coupled to the roof such that the at least one layer of noise-deadening material is at least partially disposed between the headliner and the roof. The headliner includes a noise-reflective material and a noise escape region that comprises at least one opening configured to allow sound waves to pass through the noise escape region into the at least one layer of noise-deadening material and reduce noise reflection by the headliner to the operator chair.
