Garage Door Guide: Understanding Garage Door Acoustics

Garage Door Guide
One of the biggest noise complaints from homeowners and renters is hearing or feeling the garage door opening and closing. This is especially true if you have a bedroom or other noise-sensitive room above or next to your garage. A noisy garage door can make the adjacent living space a place no one wants to be in, but how do you make it quiet? 

The noise you hear above or near your garage is caused by vibrations generated by your garage door system’s motors, tracks, and rails and transmitted through the strong connections between your garage door’s infrastructure and your building’s structure. This type of sound transmission is called structure-borne sound.

Structural Noise and Garage Door Insulation

Structural noise spreads along the supporting structure and is often  heard throughout the building. The most effective way to reduce structure-borne noise is to address it at its source by acoustically isolating the connection between the garage door system and the building structure itself. 

In most cases, simply acoustically isolating the garage door from the ceiling will achieve a comfortable noise level. The products and basic installation instructions presented here are intended to provide information on the options and common tasks required to install soundproofing materials for  garage door systems. 

Remember: Always follow the manufacturer’s safety and installation instructions for any project. This reduces the risk of errors and accidents. However, check the warranty terms first. You must do this if you are purchasing new door parts, panels, or door openers. Some products require installation by a professional garage door technician or  the warranty will be void.

Major Components that Affect a Garage Door’s Noise Level

Collaborate closely with your garage door installer to ensure a quiet installation process. Before exploring acoustical isolation solutions, opt for:

     

      • Garage door opener featuring a DC motor

      • Soft start/stop function for smoother operation

      • Belt drive trolley track for reduced noise

      • Nylon rollers in the garage door track to minimize sound.

    How to Isolate Your Garage Door’s Vibrations for Quieter Operation

    Indeed, despite top-notch components, a garage door remains a sizable, heavy object in motion, inherently producing some noise and vibration. However, mitigating vibration can address this concern.

    Consider various levels of isolation to determine desired noise reduction:

       

        • Replace door track rollers with ball bearing nylon rollers.

        • Isolate the two side door track supports from the ceiling structure.

        • Isolate the top tracks from the wall structure.
