sir alam ko may thread about sound proofing dito..
anyways, yung room ko rin nakasoundproof. ang gamit lang namin is yung tinatawag na double wall, kung saan may a wall system which is , a fiberglass sandwiched by the existing concrete wall and a gypsum board. So yung room ko muka parin typical bedroom at hindi sya mukang studio pero may capabilities sya ng isang studio.
anyways sir kung interested ka, You can pm me kasi business namin yung insulation etc.. (not really sondproofing but we can cover it though)
sensya ot!
