The Basics of Acoustic Insulation

Modern life comes with a tidal wave of noises. You hear the sounds of traffic filtering in through your windows. You hear children and neighbours pass by on the street. You can't avoid the sounds of your family members watching TV or playing video games elsewhere in the house; and you probably can’t escape the rumbling of your AC or furnace either.


Sometimes the sheer noise volume seems overwhelming. Luckily, you don’t have to live with it. If you install acoustic insulation in your home, you can limit the noise to sounds you actually want to hear.


Acoustic insulation blocks outside noise from entering a home or even a single room. We’ll tell you more about this fascinating innovation below.


How Acoustic Insulation Works

Sound waves travel fast, and they bounce off of any gaseous, liquid, or solid substance, so you may feel doubtful when you hear that insulation can muffle them. However, when sound waves bounce from one medium into another (for example, from a gas to a solid), the waves lose energy and change speed.


Acoustic insulation takes advantage of this phenomenon. It forces the sound waves to travel through materials with different densities until the waves slow and dissipate. Usually, the insulation contains foam in egg-like shapes with miniature air bubbles. The soft foam and air bubbles muffle the sound before it reaches the drywall in your home.


Manufacturers can also create acoustic insulation with other methods and materials. In any case, all methods make your home more private and peaceful.


How You Can Benefit from Acoustic Insulation

When you call professionals to install this type of insulation, they fill every centimetre of space behind your walls and ceilings with the material. This creates a virtually impenetrable barrier between your home (or individual rooms) and the outside world. This barrier has many benefits, including:

  • Your next-door neighbours can throw a huge party all night long, and you’ll sleep soundly, undisturbed in your bed.
  • One of your children can practice an instrument in one room while another child studies for school in an adjoining room.
  • Your spouse and his or her friends can watch the game or some movies downstairs while you quietly do your own activity upstairs.
  • People can shower early in the morning without disturbing anyone else.
  • Your furnace or air conditioner won’t wake you up every time it turns on, so you’ll get a better night’s sleep.
  • The garage door won’t disturb you every time it opens or closes.


Think of how peaceful your home will be after you get acoustic insulation. With insulation, you can control the sounds you hear when you enter a room. You can play music quietly, or you can watch movies or TV shows without fear of missing anything.


However, before you install this insulation, consider where you want to put it in your home. You can put it all around your home. But if you have a tight budget, you might want to insulate only the most important rooms in your home.


Where to Install Acoustic Insulation

If you can’t insulate your entire home, consider insulating the following smaller areas instead.


1. Furnace Rooms
Even a new, undamaged furnace makes noise. It whirs as it comes on, and sometimes that whir has a lot of volume. And if you have an old, clunky furnace, it probably makes even more noise when it comes on. Call a professional to install acoustic insulation around your furnace to eliminate this noise.


2. Home Offices
If you work from home, you will need peace and quiet while you fulfill your obligations. You don’t want a passerby on the street to disturb you, and you don’t want your children’s antics to interrupt you either. Acoustic insulation will ensure you have a quiet environment.


3. Laundry Rooms
These rooms need acoustic insulation for the same reason furnace rooms do. Washers and dryers make a lot of noise, and insulation keeps that noise to a minimum.


4. Bathrooms
Bathrooms need acoustic insulation for several reasons. For example, if you or your spouse bathes early in the morning, you don’t want the noise to disturb the other partner. Acoustic insulation prevents frustration and embarrassment.


5. Home Theatres
Even if you only have a living room, you may want to insulate it from the rest of the house. People use this room to entertain, to play games, and to watch movies. And as they do these activities, they’ll make a lot of noise, disrupting everyone elsewhere in the home. Soundproof insulation prevents this problem and keeps everybody happy.
