The ATR 42-500 cabin layout benefits from the improvements in noise and vibration:

Attachment of the panels and overhead bins to the structure by specially designed dampers, avoiding vibration transmission from the structure to the interior furnishings
Cabin partitions treated to reduce reverberation phenomena in the forward and rear cabin area
New insulation blankets with an optimized thickness and made of waterproof material
Stiffening of frames located in the propeller area
Installation of Dynamic Vibration Absorbers on the upper side of the frames and on the floor beams, greatly reducing the transmission of noise generated by the propeller blades
Skin damping treatment through viscomaterial strips on the panels, reducing noise propagation by the skin

The standard cabin layout is 48 seats at 30-inch pitch.

The new 568F six-blade Hamilton Standard propeller is specially optimized for low cabin noise in climb and cruise and low vibration.

It features:

New Propeller Electronic Control
New Propeller Valve Module, ensuring very accurate propeller speed and phase control
Optimum synchrophasing between the two propellers, resulting in optimum comfort even in turbulence
