Struktur yang berpori dan permukaan masa yang tinggi, ditambah dengan kemampuannya untuk meredam energi getaran mekanik, sangat mengurangi polusi suara di luar lingkungan dan efek gema dalam ruangan (yaitu mencerminkan suara) di kamar kosong, membuat lebih tenang, interior yang lebih nyaman bagi penghuninya.
Hebel AAC memiliki sifat isolasi suara luar biasa melebihi bahan padat lainnya dari berat dan luas permukaan yang sama.
