The problem you have is your the only one affected in your Strata. I’m not familiar with WA Strata rules but I would assume they are similar to other states.
To enforce the noise bylaw you (or the strata or SM) would have to go to conciliation and then adjudication to get a ruling against the offender.
Problem is this is time consuming but cheap if you DIY or someone from the Committee does it. If the SM does it they will charge for time and expense (our SM estimated they would charge on average $5,000 5 years ago for a simple ruling).
So unless the Strata is very generous using the SM is out (and a Strata lawyer would charge even more) so it’s either find a knowledgeable neighbor or become a fast learner.
