Echo

On’yomi: きょう
Kun’yomi: ひび
Radical: 音 Sound (Kangxi 180)

Mid-frequency: not on every page, but regular in books and magazines.

More common than 商 (Merchandise), less common than 緒 (Cord).

Poop and root on top, building and sound on the bottom — the root of the poop smell echoes through the building, the sound of complaints bouncing off every wall.
