The homeowner, residing in Kaohsiung, needed to practice the saxophone at home. However, the volume of their practice sessions was causing them significant psychological distress, preventing them from enjoying relaxed practice sessions. To address this issue, they decided to switch to Blue Whale’s highest level of soundproofing: the 180-type professional soundproof door, along with the Blue Whale TW sliding soundproof window. The door and window were designed to complement the interior decor, providing both aesthetics and sound insulation. With this solution in place, the homeowner no longer needs to worry about noise escaping their home and disturbing family members or neighbors. They can now happily enjoy the pleasure of playing music at home without any concerns.
