1. A noise attenuation assembly for a ball valve, the noise attenuation assembly comprising:
a ball body configured to selectively permit fluid flow through the ball valve via a fluid pathway having a ball inlet and a ball outlet, the fluid pathway extending in an axial flow direction through the ball body, the ball body defining a first unitary body having first, second, third, and fourth constraint surfaces; and
an attenuator forming a second unitary body having an array of openings that collectively form an attenuator inlet and an attenuator outlet, the attenuator inlet configured to be aligned with the ball inlet,
wherein the second unitary body of the attenuator slots within the first unitary body of the ball body so that each of the first, second, third, and fourth constraint surfaces contacts the attenuator to directionally secure the attenuator relative to the ball body.
