GAP BLOCKING DEVICE OF A HULL DOOR FOR MEASURING SOUND INSULATION PERFORMANCE, WHICH CAN BE INSTALLED IN A HULL DOOR AND A DOOR FRAME

摘要

PURPOSE: A gap blocking device of a hull door for measuring sound insulation performance is provided to improve reliability with respect to result measuring sound insulation in a hull by blocking a gap between a hull door and a door frame.;CONSTITUTION: A gap blocking device of a hull door for measuring sound insulation performance is formed into a blocking frame(110). The blocking frame is attached in a hull door and a door frame by magnetic force to cover a gab formed between the hull door and the door frame. The whole or a part of the blocking frame is made by a magnetic material. The blocking frame includes a magnetic force generation part.;COPYRIGHT KIPO 2012
