Thanks to TE members for soundproofing ideas
Thanks to all for your concern and helpful suggestions. It amazes me that TE members can provide useful information about so many subjects. I am grateful. :)
I saw my friend Linda yesterday and she offered some clarification about the noise level -- loud enough that she hears voices on the TV, but not blasting. If she did test the decibel level, I doubt it would help her case.
The suggestion to pursue help through her church, the Boy Scouts or some other community organization seems possible. She is an active member of a Unitarian church, and we might find some help there.
We also took a good look at her space yesterday and I asked her about areas that are quieter during the times her neighbor makes noise. She said the bathroom is most quiet, but since it is rather small, sleeping there would not work.
Even so, she has a walk-in closet adjoining the space between the bathroom and living room which is just large enough to fit a twin bed. It also has louvered wooden doors separating it from the living room area. Yesterday she was very open to the possibility of using this area on the nights when noise prevents her from sleeping in her usual space.
We also talked about putting insulating material on the louvered doors. She might pay a couple hundred dollars at most for the insulating material, but yes, she would rather take an even less expensive alternative.
She would try the egg cartons on the doors if it would work. But, do I understand correctly that this wouldn't really help? :confused:
Linda does own a white noise machine, but I don't know whether she uses it in combination with her earplugs. I'll ask her about that and suggest she use both simultaneously.
I'll also suggest the brand name earplugs one of you mentioned -- thanks. I'll tell her about your experience with custom-made plugs being less effective.
As it happens, yesterday Linda asked me to write a letter to the owner of the apartment where the renters are making noise. Apparently she'd spoken to building management and the renters before about this problem, but not to the unit owner.
(To give you some perspective, her apartment is in one of two buildings -- I'm guessing 20 stories high -- with hundreds of residents, some who own and others who rent. Linda owns her apartment.)
Anyway, I wrote the letter asking the unit owner to get the tenants to quiet down, sticking to the facts and keeping the tone polite and businesslike. We'll see if it helps.
Again, thanks to all for your ideas. I also appreciate your links to the earplugs and soundproofing materials. :) :)
