Are some types of doors better for sound isolation than others?

Yes, some types of doors are better for sound isolation than others. Solid core doors are better for sound isolation than hollow core doors. The thicker the door, the better it will be at blocking sound. Weatherstripping and a tight fit between the door and frame also help with sound isolation. Additionally, doors with sound seals or acoustic gaskets are specialized for sound isolation and offer even better performance.
