So, all my prayers to the 3000 gods out there hasn't worked, and the foghorn next door has just renewed her lease. ****. So I'm going to need some sound proofing ideas and advice for our patio that sits adjacent to hers otherwise its going to be the 24/7 summer of hell, when she'll keep her patio doors open. We shut ours usually as she's just unbearable. Our living room opens up onto the patio next to hers. A wall separates us which does work for normal voices. So anyone out there got ideas that don't involve duct tape. I get that her sound is airborne rather than impact noise, but could I add some mass to the separating wall perhaps, like some sort of barrier to at least reduce it? Cheers
Edit: Even with our windows and doors closed up and the TV on at a comfortable volume we can still hear the foghorn.
