What is a jet aircraft hush kit?

Explanation:
A jet aircraft hush kit is an aerodynamic device added to the exhaust nozzle to diffuse and mix the exhaust flow with surrounding air, which lowers the high-velocity jet noise. By making the exhaust flow less abrupt and turbulent, it reduces the sound generated by the jet plume. It isn’t mainly about fuel efficiency, it doesn’t purposefully increase noise, and it isn’t insulation for the exhaust.
