The first noise you hear when someone enters your home is usually from the door slamming behind them. That is the alarm that someone is home, but what if that frightening noise never happened. What if there was silence that was followed by silence? Learn how to soundproof a door below.

Top 4 Ways to Soundproof a Door

Previous suggestions for making your doors quieter include putting rubber bands around the door knobs both inside and outside. This approach, although a simple fix, is not effective and neither is the quality of the rubber bands as they tend to snap early and often.

First, determine what your primary door noise issue is. Is the door making noise when it slams, or squeaking on the hinge? Is conversation audible on one side of the door from the other, and the sound is passing through a light-weight door, or underneath where the threshold is worn away, or non-existent.

1 – Fixing Sound Passing Around a Door

Some older houses have rather large gaps that leave an undesired airflow underneath their doors. In some cases, this airflow can even lead to a howl or a whistle which can get very annoying. Adding a Door Sweep or a Door Seal can help greatly in reducing outside noise, airflow, and noise caused by the airflow.

A Door Sweep is designed to create a tight fit around any door and also canceling out any airflow that may be flowing through the underside of it. This will reduce the noise flowing under the door. To determine if the sound is flowing under the door or not, use a paper test – if you can slide a piece of paper cleanly under the door, then sound can easily pass through that space.

Although very similar to the door seal, the Door Seal reduces any form of noise transfer through a tight fit against the threshold of the door rather than underneath it, like the door seal. It comes in various sizes to fit any door and will fit on any door regardless of age.

2 – Soundproof the Door Itself

Ultimately, if you fix the flanking path going around the door, then the sound is traveling through the door panel itself. In apartments and many multi-family communities, it is common for doors to be hollow-core, meaning that they only have thin door veneers on each side of an empty shell. The low mass of this door allows significant sound to pass through.

A better soundproofing door would be filled with insulation, to fill the cavity. However, ideal doors would be solid-core, and weigh (and cost) significantly more than hollow core doors do. Most multi-family codes require doors to be STC 32 and above.

If your door is already installed, then consider Soundproofing you Door with the AcoustiDoor. It is a soundproofing door panel that hangs over doors and seals around the side to prevent flanking. The heavy core prevents sound from passing directly through it as well.

3 – Fixing Door Slams

However, as explained by Life Hacker, one very effective way of silencing your door is to add felt pads to the inside of the door frame. When the door is shut, instead of shutting on the door frame material, it shuts on the felt pads which cushion the door. This, in turn, provides with a very quiet door.

4 – Fixing Door Squeaks

If it isn’t the slam that is bothering you as much as the squeakiness of the door, then try some latch sealer. Simply spray the door hinge pins and wiggle the door back and forth. If that still doesn’t work, then you can always remove the pins from the hinges and put some lubricant in the form of lithium grease on them.
