I have interior doors which have enough space on the sides and the bottom where one could put weatherstripping to keep out the noise, but will this do much good and what type of weatherstripping would be the best?. Is there some type of stripping, weatherstripping or otherwise, made with soundproofing in mind?
Sure! go to "Soundproofing doors"! http://www.soundproofing.org/infopages/soundproofing_doors.htm
