Operator cab for a work vehicle with reduced noise reflection

A work vehicle, comprising:

• a chassis;
• and
• an operator cab carried by the chassis, the operator cab comprising:
• a cab enclosure comprising 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 comprising a noise-reflective material, a concave region comprising a pair of opposed curved surfaces that direct sound waves toward the operator chair, and a noise escape region disposed between the pair of opposed curved surfaces, the noise escape region comprising 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.
