Isolation acoustique : Le classement AC comprenant 4 catégorie dans un ordre croissant, correspond à un niveau d'affaiblissement exprimé en dB(A) Route. Plus il est élevé, meilleure est l'isolation acoustique.

Malheuresement nous négligeons ces études dans nos projets.

Exemples: (Hôpitaux, Ecoles, Crèches....)
