Ox, I am so sorry that you did not get a better reply to your polite note. So, I have this awesome dog trainer that has given me all sorts of great ideas. For instance, my dogs bark at strangers in my house. Well, I will need to have strangers in and around my house in a few months to do foundation work and I can’t take my dogs to boarding. (I have one dog that is “special needs” and a flight risk and I already went through one episode of not sleeping for 76 days as I tracked her down to bring her home safely. Really can’t do that again). Anywho, I have to have the dogs here for the foundation work and I do not want to bother any of my neighbors so I am going to sound proof my garage so I can have them in there while they do the major work. (I will properly ventilate and such first too). My trainer has sent me info on materials that might be useful for the sound proofing that I could share with you if that might help you in your home? I was thinking of suggesting this to my neighbor too, but I am afraid to bring that up with him since he is so volatile. My trainer had another suggestion that might be useful on my side and my neighbor’s side which is heavy drapes on the side of the house that faces his. And, what works for me in general whether it is power tools or the neighbors i had with the howling dogs — white noise. It won’t completely block the sound but it certainly helps. Good luck to you! PM me if you want the sound proofing info.
