The closest I can think of are
- gradual increase in volume and
- playing with panning to start from left or right and gradually moves towards you
center(i think you might need to physically place the output speaker so the left or right its playing from is farthest away from you)
Feel instinctually like reverb might have some application here but i know almost nothing about it
Subtle Doppler effect if you want it to be really accurate. Raise the pitch slightly and gradually add it gets ‘closer’. If understand if it’s music and that would mess with things though
