A door having acoustical sound isolation properties includes a rail or stile having surfaces with a first, second and third planar portions stepped inward from and parallel to each other. Blocking layers are disposed parallel to and below one of the door surfaces, with each blocking layer having an edge with an extending flange contacting and extending along the second planar portion of the third surface of the stile or rail. The flanges of the blocking layers restrict movement of the layers toward each other. Soft acoustical material is disposed in the door interior. Flexible transition layers extend along the stile or rail third planar portions and extend over the blocking layers and the soft acoustical material to provide support against denting forces to the door.
