The cost of soundproofing a home studio starts from £4000 to £5000. Of course, depending on your star power, this could be significantly more. So, until you become famous, with soldout concerts to your name and a Grammy on your mantel you are going to have to learn how to soundproof your garage for band practice. And unlike a home studio, it is significantly less expensive.
The garage is a perfect place to set up your musical equipment and jam out with your bandmates. But, all of the noise while pleasing to your usual audience may be bothersome to your neighbours. So, to ensure that your neighbours don’t hate you, we have compiled a step by step process to help you soundproof your garage.
How to Soundproof Your Garage for Band Practice
Step 1: Start With the Window
You are about to trade natural air and the view outside your garage for music, but that’s okay because the Grammy will be worth it. So, to soundproof your window, you can create a DIY window plug and put it on your window whenever you want to practice. The upside to this option is that you can take it down whenever you want and, you can make it yourself.
Another option is that you can brick your wall. The advantage to this is that it is cheaper, more efficient and long term, but unlike the window plug option, you cannot take it down after practice. Both of these options will need you to find an alternative source of ventilation. You cannot practice in your garage without air. So, you can get an air conditioner or a fan, whichever works for you, make sure you have ventilation.
Step 2: Do the Garage Door
After you’ve taken care of the window, move to the garage door. Since it’s a garage door, it is wide and moving, so that might present some problems. But not to worry, these options will help.
Your first option is acoustic blankets. They are made out of materials that contain sound-absorbing qualities. Depending on the size of your garage door, you’d need to get as many as is necessary to soundproof it.
Another option is to cover all gaps or spaces on the garage door using a weather-stripping tape. That will stop the noise from leaking out. There are tapes that you can use specifically for garage doors, get them and use them.
Step 3: Then the Ceiling
There may be no pressing need to soundproof your ceiling; however, there is nothing wrong with being thorough. To soundproof your ceiling, you can also use acoustic blankets. They work just as well for ceilings as they do for doors.
You can also use soundproofing foams. They are more effective and will significantly reduce the noise. They are also great for absorbing sound. If you can’t get acoustic blankets or soundproofing foam, you can get moving blankets or regular thick blankets and nail or glue them to your ceiling.
Step 4: Now the Walls
Unlike the garage doors, you can’t skip the walls. Garage walls tend to be thin, and thin walls make for well, loud noises. It’d make it easier for the sound to travel.
So, to soundproof your walls, you can use acoustic blankets and nail them on the walls. If you have regular blankets or moving blankets, you can use them too. However, acoustic blankets are a better option because they can absorb 50% of the noise. That, added to your other soundproofing actions in the garage will keep your garage appropriately soundproofed.
Step 5: Finally, the Floors
Okay, you don’t want sound bouncing off the floor. Since there will be a lot of drumming, you are going to need to cover the floor with thick carpets/rugs. To make it even for effective and stop the drum sounds, you can place a drum rug on the rugs/carpets before you put your drum. That should effectively absorb the sound.
If you have speakers, you can also “float them” by putting thick pads under them to absorb the sound.
And, as another alternative, you can:
Build a Room within a Room
If you go this route, it will cost you more time and labour. But it is a very effective option. What happens here is that you will hang three layers of wall within the garage to block out the noise. That can be a complicated process so you may need professional help. It is also a permanent one, so if you have other plans for your garage, you should probably not do this.
In conclusion, the five mentioned steps are sufficient for soundproofing your garage, but if you want to take it a step further, then you can try for the alternative. As mentioned earlier, nothing wrong with being thorough.
