My wife wants me to consider soundproofing the wall just outside our main bedroom, to deflect the noises coming from the neighbor's dog. The dog is unusually loud - like gunshots... very fast and very loud.
We have a 6.5-foot high wooden picket fence between the two properties. The exterior wall is built of drywall (inside), 2x4 studs, pink insulation batt, an outer moisture barrier, and 5/7" plywood paneling. (pretty standard)
Though I believe in the effectiveness of soundproofing an exterior wall, I'm not sure how effective it would be since we have a large sliding glass door window on the adjacent wall facing the pocket into our U-shaped floor plan. See attached diagram. It seems like this pocket of bouncing sound all around might make the task a moot point.
Would a soundproofing endeavor of our exterior bedroom wall be worth the effort, given this acoustic dynamic?
Thanks for all you do.
