많이 비슷하긴 하지 ㅋㅋㅋ

너무 현실적으로 받아 들이면 안돼~ 실질적으로는 아마 두개다 서로 영향을 줄테니깐

1. adaptation: your sense basically "adapt" to it because of the "constant" stimulation.

2. habituation: now this is more towards whether you "focus" on it or not.

Of course, BECAUSE of the constant stimulation, you can think that you DO NOT FOCUS on it.

But make sure you distinguish the two. One is focused on the fact that you adapt to it because of the constant stimulation, 

and the other one is focused on the fact that you don't really focus on it, so you feel less of the sensory stimulation.
