Urbnlivn (a Seattle real estate blog) posted a fascinating article about the challenges associated with soundproofing condominiums earlier this week. While a certain amount of sound transmission between units should be expected in most condominiums, excessive noise can prevent residents from enjoying their homes and (in the absence of other solutions) lead to litigation. Products such as mineral wool, ceiling clips, and acoustical sealant may be able to adequately address serious noise issues at a reasonable cost. Since many condominium declarations restrict owners' ability to change flooring or perform other renovations, it is a good policy for owners to check with their condominium's board of directors before beginning any soundproofing project.
