The first night in a strange room teaches you which sounds your old room had taught you to ignore.

A new room reveals your old one by contrast. Every unfamiliar creak and hum keeps you awake, not because it is loud but because it has not been filtered yet, which shows how much your usual environment was being actively ignored rather than genuinely quiet. Comfort is largely made of practised inattention.

Expect the first nights anywhere to be hard, and expect it to pass as the filtering builds itself. And take the moment as information: you have a great deal of skill at not noticing, which serves you well at home and can also keep you from noticing things that deserve attention.
