A fluid flow control device having a body having a inlet connection, an outlet connection, a discharge port and a booster module disposed within the body. The booster module including a control element and an actuator element having a noise-reducing trim element with a supply path extending between the inlet connection and the outlet connection and an exhaust path extending between the outlet connection and the discharge port. The noise-reducing trim element being coupled immediately adjacent to the discharge port such that the noise-reducing trim element distributes a fluid flow to the discharge port via the exhaust path into a plurality of fluid jets to substantially inhibit jet recombination at the discharge port.
