Protect animals from drums in the next room.-Acoustics Forum-Acoustic Fields Forum

I am setting up a practice space for my band in my living room and I need to reduce the noise levels in the adjacent room. I don’t need total sound blocking, just enough to protect my cats hearing when they are in that room. Does anyone have experience dealing with a similar situation and if so how did you deal with it? I am having a hard time finding solutions online and was wondering if any of you had some suggestions.
