I can faintly hear things through the walls sometimes, but not very much. Definitely not any words. It doesn't bother me, but if I could hear actual conversations, it totally would. I remember the first time I went there my T asked if the noise through the walls bothered me, and offered to put on a noise machine. I didn't think it was at all necessary though, since I couldn't hear much anyways. Sorry you can hear so much!
