Loud Neighbor, please help!

Hi, I hope you guys can help with advice about my situation. I'll try not to ramble... I'm a single mom who has my son 90% of the time living upstairs in a triplex. I have lived here for 6 years (great place over a golf course, have my own yard, vaulted ceilings, you can walk to the beach). When I moved in there was a family of 5 below me that I never, ever heard a peep from. They moved and for the last year I've lived over a guy who is 50 but thinks he is 20, who constantly blasts his tv and (shitty) music on his stereo and it vibrates my floor and makes it impossible for us to watch tv in my living room no matter how loud we turn up the volume. Forget trying to read or even think. He is in construction and works weird hours and sometimes nights so he is home alot and I never know if the noise will be 20 minutes or all day and night. He claims to be "unaware of how loud he is" because he is hard of hearing from working the machinery. Regardless of his cluelessness, I have always kept my son from jumping around on the floor and refrained from making noise in the morning when I know he has worked all night. A few times his music or tv was so loud I have gone downstairs and asked him to turn it down and he has been nice about it and done so, until he forgets and does it a few days later. He was asking me out for awhile and I got sick of being nice and finally made it clear there is NO WAY it was ever going to happen. Since then his music and tv are louder and more frequent. I was laid off from my job and I'm home alot (due to a limited entertainment budget). As I type this I am blaring the tv (I bought surround sound too hoping to combat his noise but it doesn't work because his tv is on the opposite wall and much louder, my floor is vibrating right now). I have been beating and pounding on the floor for 3 hours and no change. I invited my next-door neighbor to hear (just to see if I was being unreasonable and she said it was crazy loud - they are over the laundry room and can't hear it). I am too mad to go down there and calling the police won't help because I am the only one who hears it, it's not as loud outside. When my son gets home I plan to send him down there to guilt him into being quiet. As much as I want to call the landlord I feel badly about causing problems (he likes low-maintenance tenants and in return the rent is the lowest on this cul-de-sac). He (landlord)has been really cool about the 2 Chihuahuas I have because he doesn't love pets and he even lowered my rent when I told him I lost my job and also let me slide for a couple of months and I know he is struggling financially too and could rent out my place for alot more. Also, if I tell the landlord then the neighbor will know and it will be even more awkward. I can't afford to move until I have a new job - my 401k is spent and so is my savings. I could also tell the landlord he smokes in there (he lied about that and it comes through my windows and vents) and that he has alot of parties (this is not a party place, that's why I picked it, I can go to one of the many, many local bars to party) but I haven't, but I'm at the end of my rope here. What can I do to fix this??? If you made it to the end of this post and have any thoughts or ideas I'm open to them, and if you think I'm being an unreasonable bitch you can say that too, I don't know anymore.
