Choose notes that match morning and night—citrus or mint for action, cedar or neroli for exhale—and place diffusers near airflow, not faces. One reader swapped candles for reeds by the vent; guests noticed clarity, not perfume, and the kitchen linger stopped dominating the whole apartment.
Treat silence like a material. Add door sweeps, felt pads, and acoustic art panels disguised with fabric or prints. A busy street faded after a renter lined a bookcase with mineral wool and canvas, transforming echo into hush while the room looked smarter, not padded.
