1. A method comprising:
producing an acoustic field from a transducer array having known relative positions and orientations;
defining a control point wherein the control point has a known spatial relationship relative to the transducer array;
assigning an amplitude to the control point;
generating a mid-air haptic effect for a user by traversing the control point in a closed curve,
wherein the closed curve comprises a first portion and a second portion;
wherein during the first portion, the control point activates haptics, and during the second portion, the control point activates reduction of audible noise.
