broken mirror on Monarch Mirror closet doors

Hey guys.. I've got a window in our bedroom that seems to let in LOTS of noise from our neighbor's house. It usually isn't a problem unless their dogs are barking and then it sounds like the ^*(% dogs are in our room. Last night the parents went out of town and the kids were a bit ruckus on the patio and we were awoken a few times. So that's the backstory. The windows are single-pane double-hung windows if I'm correct. It's basically two separate windows hung back-to-back with a 1/2" to 3/4" gap between them. What can be done to dampen the sound? Your help is greatly appreciated by both me and my wife!!

Hi All, I really need some help here. I am somewhat of a novice at doing things myself. Although, I am a mechanical engineer and design complex machinery for a living. I have placed a picture here to show my predicament. I have a slab house with no attic. I want to put a door in an existing room. I tore down the sheet rock, because the texture was horrible. The picture below is what I found. The wall is 8 ft tall. On the lower part of the wall runs a water pipe (copper) and two electical lines. I was thinking of routing the piping under the door I want to put in by removing some of the slab, running the copper down and then covering it back up with cement. Other than that I don't see many other options. I could run it over the door I guess. Also, to make a turn in a copper pipe like that means cutting and joining somehow. The methods for joining a copper pipe seem to be saudering or compression fitting. I am against saudering because of access and I am wary of doing a poor sauder joint. I guess that's enough said. Here is the picture. What do you think? Regards, Jimboy
