    We live in an old (110 yr+) farmhouse. We also live 3500 feet from a granite quarry and are assaulted by the noise from the jaw crusher and hydraulic hammer from dawn to dusk every day. Even though they are in noncompliance re: county's SUP, it doesn't matter. The quarry does what it wants without oversight. County looks the other way.

    We're considering adding insulation to the walls -- would that make much of an effective sound barrier? Even minimizing it some might save our sanity (I think after so many years of the roar and pounding, our sanity is already gone).

    It's mainly the low frequency that we have to deal with but it isn't background noise. It's in your face.

    Any suggestions would be helpful (and don't think we haven't thought about moving but we love our farm).

    Not much that will kill low freq waves short of a thick rock wall...

    Also a lot of what you are hearing is being transferred through the ground and through your foundation... sub bass, anything below 30hz is some really wicked stuff that is almost impossible to isolate from, especially when being transmitted through the ground.

    I've got some really serious subs in my living room, and I have to be careful because my neighbor hears them in his house... we have about 40 feet between our houses, and the wall on his house is brick... Both of our houses are insulated well in the walls too.. .

    About your only option being next to a quarry would be moving..

    One other thought... Even if you could insulate the walls, your windows are acting as drivers to help amplify the bass..

    How depressing! do keep your neighbors in mind -- it's awful to have to live with it 10-12 hrs/day.

    Oh I do... I seldom crank up my subs.. and when I do, I usually either keep them low, or when I do crank them up, it's when the neighbors are gone...

    Besides, they can easily do some serious damage to my house if I drive them hard for long..... and since I rent..... ...

    So when you bought your place you didn't know about the quarry, or didn't understand the kind of noise pollution they put out?

    I sure hope they don't blast there...

    You should look at various soundproofing walls. Some involve 2 walls with an air gap.

    Must be someone that could come look, might be a quick and dirty help like insulating the floor with fiberglass, or hanging thick curtains on the wall.

    Someone must have a kid with a drum set in the garage that could offer something.

    Quarry was here but they were to close down in 2010. Then they decided to expand and despite objections from the community, they were allowed not only to expand but also to move their primary crusher closer to where people live. It's been a mess, and we've fought for so long and got nothin' -- it's been a lesson in reality. You follow the money, you see who is on whose side. County commissioners, county planning, county health -- turn the other other way. It's worn us out (those of us who still try to fight Martin Marietta who owns the quarry) and of course that's what they knew would happen. We have no money to fight then in court. They are a Goliath. Even as I write this, I can hear the crusher: it's like listening to giant drums banging away (a better analogy: metal on metal). Imagine having to hear this day in and day out. The only quiet we get is if we leave our home.

    Gosh, sorry....don't get me started!

    Sound of rock crusher and excavator mounted jack hammers and rock drills is nothing like a lawn mower next door... You have to remember how loud what you are hearing is from 3500 feet away.. that's over a half mile.. .The type of deep bass frequencies you are dealing with are really hard to stop..

    I'm a very active member on an audio forum, and we've always got people asking how they can stop their bass from disturbing their neighbors, and the standard answer is turn it down, or don't use the subs.. There are other ways, but they are expensive, or drop the db of the bass output.... it's really hard to isolate deep bass, especially that which is conducted along and through solid items.... The items they are traveling through act as resonators and help resonate the bass into the space on the other side of them...


    You MIGHT cut down on some sound a small amount using some very extreme measures, but the cost isn't going to be cheap... Short of building a second wall around your house and over you roof, and mounting your house on isolators, you're not going to be able to cut back on the type of sound waves you're dealing with... You really have to be able to picture sound waves in your mind and how they travel and effect solid objects before you'll be able to understand what you're asking to do.. and then will realize it's pretty much futile..

    Some people add a second wall on sides of the house where noise is worst. We thought about doing that, but have gotten used to the noise instead.

    This...

    I too have a killer stereo in my home, but since I have to put up with my neighbors crappy yard and mowing lawn after dark, rarely do I consider him when playing it...nor does he ever complain.

    Low frequency is more of a pressure wave than a sound, like semi said...it's hard to dampen or sound proof for it.

    Lemme put it like this... These are the subs I am running.... They may not look like much, but they are on a 700 watt per channel pro amp...

    I have shaken dishes outof the cabinets in the kitchen two rooms away.... I have knocked all kinds of things off the shelves upstairs at the other end of the house...

    And my neighbor across the street and catty corner from us, about 250 feet away has said he could hear the bass in his house fairly loud.. during the winter, with his and my windows closed..

    The speakers sitting on top of them weigh about 100lbs each, and I can cause those to walk most the way off with about 15 seconds of playing just the subs at about half the volume I could actually put into them..

    Now think if those 12" drivers can put out bass frequencies large enough and loud enough that a neighbor can hear them in his house, at 250 feet what kind of waves you're dealing with out of a huge rock crusher at 3500 feet..

    (BTW, These are my small speakers.. you should see what I got in the basement :D)

    You got me beat, but like you I have 2 subs, one of which is a 12" and it's knocked stuff off the tops of my cabinets. I have a set of 3 way Sony I purchased many years ago that surprisingly sound pretty dang good for what I have in them.

    I also have my Mac and a PC hooked to my 40" Sammy the iPhone as my remote as well as my Logitech remote. My PC runs plex and my Mac runs XBMC.

    My next setup will likely be home built boxes and a new amp with more power...I'm using an old Sony amp (before they were 2" tall) and I've had I re solder the LCD and two places on the main board due to cracked solder joints...it's been a good one and I will miss it when it finally dies. No HDMI inputs on the amp so everything is fed directly to TV except sound.

    The boxes on top I designed and built in some old Barzilay cabinets... The drivers in them are all pro drivers. The woofers are hand built in the US and used in some large Planitary places here in the US... I also built the crossovers in them... they have something like 6 resistors and 12 caps in each one, and each horn is controlled with two L-Pads..

    Like I was saying though.. those are my small speakers... Here's my big ones.. they came out from behind a screen in a NYC theater... The bass isn't near as intense, but the SPL levels are much greater... They didn't complain about the bass from these, but the over all levels..

    I'm using these as examples to maybe help the OP understand what they are dealing with... yes, these are big, but not near as heavy with the bass. The bass frequencies are also not near as deep, or low... ... but even with these the sound travels far, and through walls and the foundation of my basement... If these can project sound as much as they do, imagine what it's like when you'r talking TONS of rock and steel banging together... There's just no way you're going to control or defeat the waves....

    It's basically like asking how to stop the sound of a constant explosion from entering your home...

    (BTW, that's a 52" TV to put a perspective on the size... )

    When I lived in Cincinnati, we had a set of train tracks that were 16' from my front door. The main part of the house was built in the 1840's, and the street it was on was sold to the railroad in the 1930's. It wasn't heavily used, but we'd average two large freight trains daily. I had a hell of a time getting insurance because there is no way you can build that close to active tracks lol. The noise was ridiculous, and forget watching tv until it passed. Things would vibrate like crazy if it was a heavy train. One cool autumn night we slept with the bedroom windows open which face the tracks. I don't think anything can be scarier than a freight rolling by at 2:45 am. He hit that horn just as he reached us, and the light in the bedroom was blinding. Needless to say, it was the only night we left the windows open lol.
