Every Room Deserves Great Acoustics
When most people think about good acoustics, the first area of a home that comes to mind is an entertainment room. The audio in this space should be pristine—from clear, intelligible dialogue to realistic, three-dimensional special effects. You feel as if you’re in the middle of the movie action, and proper acoustical engineering and treatment of the space contribute just as much as the equipment to delivering this experience. If the acoustics of the space are off, the listening experience will suffer.
To prevent this from happening, it’s important that a home theater include properly engineered and installed acoustics customized for the unique sonic attributes of the space. The floor, ceiling, walls, furnishings, etc. often require some level of modification to ensure that the movie audio sounds its very best, without reverberation, echo, or disruption from other sources of sound.
But why stop at the home theater? The same acoustical principles of a home theater can be applied in bedrooms, home offices, living rooms . . . really any space that suffers from unwanted external noise or acoustical conditions that conflict with the intelligibility of conversations. Just as a noisy heating and cooling unit can distract you from the plot of a movie, it can be a
literal nightmare when you’re trying to get a good night’s sleep.
And that’s just brushing the surface of the annoying sounds that can plague a household. Homes of all sizes and designs can be affected by excessive noise, lack of sound privacy, and an abundance of sound propagation.
Think about the things you hear at home on a daily basis: A delivery truck backing out of a neighbor’s driveway, the lawn maintenance crew working at the park across the street, barking dogs, the thump of the home gym treadmill at 5 a.m., and the incessant beat of your son’s garage band are just some of the many examples. They all add up to a lot of racket—most of which you’d probably rather not hear or at least muffle a bit. An acoustical engineer can minimize these audible distractions from any area of the house—not just the home theater.
Years ago, all of this commotion may have fallen on deaf ears. Most people worked in an office outside of the home, went to the neighborhood cinema to catch a show, and worked out at the gym. Today, though, we are home a lot,
using it for a myriad of activities besides just eating and sleeping. We work in home offices, exercise in home gyms, entertain in home theaters, dine in gourmet kitchens, and shop online—subject to all of the audible chaos in and around the home. We cringe when the kids arrive home during a conference call, cover our ears during our son’s gaming marathon, and wait until the baby wakes up from a nap to throw in a load of laundry. Noise can disrupt our lives in so many ways. Thankfully, proper acoustical treatments applied by a professional can help.
Often, the remedy necessitates a structural modification of the ceiling or walls. Most homes are built in a way that allows sound to easily transfer from one room to another. Sheetrock is attached directly to studs and joists, which allows sound to move from one material to the next, one room to another. Separating these surfaces through the addition of isolation clips and hangers mitigates the sound propagation. It’s an expense, certainly, and more easily implemented during the construction of a home, but there’s no better way to preserve your sleep and sanity.
Other, less extreme remedies to tame the propagation of sound throughout a home involve adding aesthetically pleasing sound absorption materials to a room, such as acoustical plaster on the ceiling surface, fabric on the walls, specialty ceiling tiles, and even furnishings. If it’s sound from outside that’s bothering you, thicker, double-pane windows and heavy draperies can help.
Sound quality has an impact on more than just our ability to become fully immersed in a movie. It’s part of our everyday life, in good ways and bad ways. We might like how our audio system sounds in our home theater, but we’d rather not hear it in the bedroom upstairs. The same goes for other noises. They’re a part of the house and our lifestyle, but left untreated, they can interfere with work, play, and even our health. A professionally trained and experienced acoustical engineer can make these issues disappear, creating a more peaceful and healthy home environment.
