Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:
If you think about an area that you're in, it's the place you're at (あた).
The area fell silent.
Oh, I forgot to tell you that there is no station in this neighborhood.
His bathroom must be somewhere around here.
