A room smells less noticeable to people inside it because of olfactory adaptation, in which the nose becomes less responsive to constant odours.

Is it true that a room smells less noticeable to people inside it because of olfactory adaptation, in which the nose becomes less responsive to constant odours?

Yes. A reference entry on olfactory fatigue states that prolonged exposure to an airborne compound causes a temporary, normal inability to distinguish that odour, which is the mechanism the claim describes. A study on repeated odour exposure also addresses habituation, though the retrieved text only describes the olfactometer apparatus.
