Chicago noise law...
Thanks I'm going to use that as a guide to see how well my soundproofing works.
Zombie thread. Banned OP. Etc.
Check with some of the wholesale foam suppliers in Chicago (Second City Foam). I'm sure you can buy egg crate foam in huge sheets up to 4" thick. It'll be easier to hang a couple large pieces than a bunch of smaller scraps. Alternatively, you can use heavyweight moving blankets. As others have said, this will help mostly with higher frequencies. You will still need to take measures to minimize low frequencies.
I would check out (memorize) your city's noise ordinance (you can probably find it on their website, or go to city hall in-person and ask for help). Find out exactly what the laws are in your neighborhood. It sounds like your neighbor has a bug up his a** and will call the cops if he hears anything. Know your rights, keep it inside legal limits, and tell your neighbor to stuff it if he continues to be unreasonable.
LOL. Just noticed that. The annoying neighbor probably croaked years ago.
Kilt by loud music
Read the local noise guideline laws for your area, could be you are within your rights already. Ask the police too.
To stop bass frequencies, adding a rubberized floor might be a better option than insulating the walls. The clear easy choice is just to practice at lower volumes or at times when it is legal.
If it's legal and the neighbor is just complaining, ignore him. Sometimes police are obliged to respond, but no law is technically broken. Could be they are just doing due diligence to keep the peace. Within legal limits you have a right to enjoy loud noise.
I typed real good too!
I’m wondering about he did with the noise after 11 years.
It is better to use acoustical blankets. These are sound blocking and sound absorption barriers that combine mass, flexibility, and limpness to block noise from transmitting from one area to another.
That foam is extremely flammable. Not recommended. To stop the low frequencies you need something heavy. OP, save up your money and soundproof it properly.
Given that it's an 11 year old question...
Build a movable insulated, drywall partition to put on the inside of the garage, in front of the garage door when the band is in there.
Blankets won't work. Egg Cartons won't work. Acoustic blankets on a frame won't truly work. Yes, the garage door will be the major leak, but the walls, edges of the blankets, windows and any side door (if any) and roof all contribute plenty enough to tick off the neighbors. About 5 layers of carpet on walls with 1-2 inches between them can do walls "kind of OK" but really, isolating your band sound in a room is harder than you know. Been there before back in the day. Ended up renting a place with no near neighbors every time and luckily we could afford it.
acoustical blankets will help you to reduce noise. These are sound blocking and sound sorption barriers that combine mass, flexibility, and limpness to block noise from transmitting from one area to another. They are available clear, non-reinforced, and reinforced in a variety of weights and styles to meet a multitude of applications.
Cheaper and easier to cut a hole in the garage, install an AC, and shut the door.
I imagine that the entire garage is acting like a speaker cabinet with the doors up.
Also, good to know your noise ordinance, and see if you can comply with it. Then if the neighbor calls cops again, and the sound levels are below that level, the neighbor can pound sand.
I recommend first getting banned by a noteworthy bass forum, and then moving to a sanctioned rehearsal space.
There is another better way is to use acoustic enclosure. It is made up of high performance acoustical fencing that is used to reduce airborne noise energy in many industrial and architectural applications. With velcro, each two pieces can be tightly collected.
Zombie blankets work best.
Still some good info here.
Take up the zombone to reduce noise!
Just checking in to provide some basic engineering information, as I have dealt with noise issues for most of my professional career I have built a couple of noise isolation rooms for the noise testing of equipment.
It's common for people to confuse measures to reduce reflection within a room, with measures taken to reduce transmission into or out of a room. Most of the off-the-cuff suggestions people make when musicians are trying to prevent annoying their neighbors, will not help much or at all for noise transmission, which is what annoys the neighbor.
Sonex foam, egg crates, soft blankets, etc., etc., etc., are anti-reflection measures and do little to nothing to address transmission. Some of the confusion comes from the common nomenclature of "sound absorbing" to describe these products.
The keys to reduce noise transmission are:
1) Sealing - close up all holes and gaps, which offer direct transmission paths for sound pressure oscillations. It is not easy to have ventilation in a noise-controlled space, because that's a huge direct noise transmission path. For test rooms for equipment I have often omitted ventilation altogether, knowing that we'll have to open the door and let things cool off every so often. You can't really do this with a band practice area.
2) Isolation - you need to eliminate paths for the transmission of vibrations excited by noise from the inside of a wall to the outside of a wall. The room-in-a-room concept addresses isolation. It is not easy to truly isolate the inside space from the outside space.
3) Mass - the denser the walls are, the more energy is required to excite the inner side of the wall, thus less energy can be transmitted to the exterior air by the outer side of the wall.
A garage pretty much fails every one of these criteria. There are usually all kinds of gaps, at very least around the garage door. Often the inside has drywall, but it's just nailed to the studs and then the outside siding (or whatever) is connected to the same studs. And the materials of construction are just whatever normal house construction materials were used.
The ideal (not achievable in reality except in extremely rare situations) band practice area would probably look something like a room with two walls of concrete block, not connected, and two ceilings of double thickness drywall with seams staggered and hung from two not-connected sets of joists, one above the other; and using a ductless split AC/heat system. The door would be one inside the next, with rubber seals all round both the inner and outer door. The interior walls would be treated to control reflections (Sonex foam, or similar treatments), ideally with some flexibility (for example, some panels that are reflective on one side and non-reflective on the other side so you can choose how live or dead the room is.
You need to keep this ideal situation in mind when trying to create a realistic practice space.
