A basic ray model is used to examine refraction and reflection of sound from an air / air interface. The results for this treatment are presented and examined for the possibility of using a heated air mass, forming an air / air interface, as an acoustic boundary at outdoor events to reduce environmental noise pollution from sound leakage from the event site.
