Door noise or sound transmission control: this article explains how to make sound-reducing or "soundproof" doors and doorways in buildings. A key component in noise control and sound privacy improvements is the elimination of flanking pathways at entrances or doors as well as using doors that themselves are resistant to sound transmission. A closet door may form a sound flanking pathway, while a hollow-core entry door may readily transmit noises outside of a room, violating privacy or creating a noise nuisance.

As described in Best Practices Guide to Residential Construction:
Soundproof double-door doorways: Upgrade to solid-core doors and add weather-stripping. Our photo (left) shows an installation of doubled solid core doors that has been found effective in minimizing sound transmission between a counseling office and its waiting room.
Addressing obvious flanking paths is often the most cost-
effective step in soundproofing a home.
Soundproof single door with glass panel
Above we illustrate a sound-proof door installed on a music classroom at Vassar College. The frame of this soundproof door with its large glass center panel is filled with sound deadening materials and as you can see in the close-up photo (above right) additional steps to reduce sound transmission through the door or its jamb were taken by spacing, glass type, and sound-absorption into the door frame.
In general, sound-resistant doors should be within 10 Sound Transmission Class (STC) points of the surrounding wall. Solid-core doors are recommended for bedrooms and bathrooms.
Also the gap between the door jamb and studs should be caulked or grouted to avoid sound leaks around the door.
A doubled sound transmission resistant interior door installation is shown at SOUND ABSORPTION vs. SOUND ISOLATION.
For even higher sound resistance ratings, which might be needed for a music room, for example, double doors are required (see our Table of Sound Transmission Characteristics of Interior Doors shown at left). You can see from the table "Sound Transmission of Interior Doors" that the example in our photo above, two solid core doors spaced 3-inches apart gives the best STC rating in both unsealed and well sealed installations.

Building noise control - flanking pathways: this article series explains how sound flanking paths, sound leaks around and through building components, defeats incomplete attempts to reduce building sound transmission and noise levels. We include design details for sound reducing details in buildings including soundproof office doorways and doors. This article includes excerpts or adaptations from Best Practices Guide to Residential Construction, by Steven Bliss, courtesy of Wiley & Sons.
