A structure for feeding and watering animals, such as cows, goats or lamas which is provided with feeding troughs and comprises an imaginary vertical axis around which the feeding troughs are disposed at a fixed distance therefrom. The sound attenuating barrier may include at least one face sheet andor core having a spatially varied stiffness distribution andor a spatially varied mass distribution. In at least one embodiment the gateway component configured to receive at least a portion of the control data, the gateway component further configured to receive media data associated with the with the communication. The system is also configured such that the distance remains smaller than 40 mm during a camber deflection of 0\xb0 to \u22123\xb0.
