Our new apartment has terrible soundproofing. We got a complaint from downstairs about our toddler running.
Solutions: a thick rug absorbs impact noise. Felt pads under furniture eliminate scraping sounds. Acoustic foam panels on the wall help too. We also apologized to our neighbor in person β goodwill goes a long way.
New buildings may have worse soundproofing than old ones, but there are ways to cope without renovating.
