hypatia42Update on the radon mitigation: we found out last week that the original system they put in place didn't bring the radon down below "acceptable" levels. So, in addition to the noise problem, it still didn't do what it was supposed to do. They came back out today to see if they could fix it.
They added more insulation to the basement to muffle the mosquito whine in the large crawlspace. They switched out the fan for a quieter one. They added a rubber bushing between the pipe and where it attaches to the house. Then lastly they added a rubber collar instead of the hard plastic one at each end of the connection to the fan housing.
These measures reduced the noise by roughly one third. I believe this to be insufficient. I was told they had done everything there was to be done and that it was far beyond industry standards for noise reduction. "I can't hear anything. Are you sure its not the air conditioner?" No kind sir, you may not gaslight me. If you can't hear bats and dog whistles, tvs and security systems I suggest you not try to tell me what I am and am not hearing. He said he would have to talk to the owner and see what else could be done.
After they left Michael and I went out to inspect and see if there was anything else we could think of. Michael noticed that the clamps holding the electrical conduit to the house are not muffled so we detached that from the house to see if it affected the noise level. Definite difference. Brought it down probably another third. Its possible that will be tolerable but the real test will be sitting on the couch with the fan behind my head for a while to see if it is truly tolerable.
Lesson here: do not try to gaslight me.
