Introduction
Sounds can trigger our fight-or-flight response. For example, when we hear an ambulance or fire truck, our first instinct is to locate the vehicle in case we need to move out of the way or pull over, which is a manifestation of our fight-or-flight instinct. A different scenario is hearing the house alarm; we often shift into fight mode to protect our home. These are two extremes, but what about the sounds that bring peace and calmness? How does acoustics shape the comfort of the home? I have a few inputs that you can use to achieve home serenity. It starts during the design of your new home.
Understanding Sound in the Home
To understand how sounds travel through the house, we should learn how they move through it. Sound travels by air and through the framing/structure of your home. It is not limited to walls, floors, and ceilings, which is why it is crucial to design these assemblies with details to prevent sound from escaping. Sounds can easily travel from space to space. Have you ever been on the first floor and heard footsteps coming from upstairs on the second level? Makes me wonder what is going on up there?! Another way sound travels easily is through the hum of the HVAC system, especially when ductwork is used. Another factor is the sounds outside your house. A busy street or even Mother Nature can make you feel like you are still outside while sitting on the couch.
Quiet Starts in Planning Design Stage
Architects and builders use two key performance measures:
STC (Sound Transmission Class): how well walls or partitions block airborne sound (like voices or music).
NRC (Noise Reduction Coefficient): how well materials absorb sound inside a room (reducing echo and reverberation).
The higher the rating, the better the acoustic comfort.
The way a home is laid out, the setbacks of the house from the street, and the layered wall assembly all play a role in mitigating sound.
Here’s what to consider when planning your layout:
Separate noise zones. Keep bedrooms and studies away from kitchens, living areas, and mechanical rooms.
Double up on buffers by utilizing closets, bathrooms, or pantries between quiet and active spaces.
Be mindful of double-height ceiling areas, as they may amplify sound if not designed effectively.
Think about finishes. Hard surfaces (tile, glass, concrete) reflect sound; soft materials (rugs, drapes, upholstered furniture) absorb it.
The upgrades to consider
Now, if you have passed the design phase and are in the middle of construction, here is what you can do! Please note that this is a change order. These upgrades are budget-friendly.
Insulated interior walls: Use sound-attenuating batts in partitions between bedrooms or offices to reduce noise.
Resilient channels: Add them behind drywall to isolate sound vibration.
Acoustic sealant: A simple but effective detail — seal around outlets, joints, and gaps.
Acoustic panels or wood slats serve as both design features and echo dampeners.
Another example of an additional upgrade is changing the doors to solid-core. Hollow doors are often cheaper; however, solid-core doors offer peace of mind and privacy.
Conclusion
Creating a balanced environment begins with controlling sound and different frequencies. You will enjoy your home more by limiting distractions and preventing oversimulating. Sometimes we overlook silence to feel busy or avoid feeling emptiness in a loud environment. Silence is a luxury for many families, and everyone can easily obtain it.
