Title:
SOUND INSULATION STRUCTURE BODY
Document Type and Number:
Japanese Patent JP2017227109
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sound insulation structure body 1 capable of exhibiting sound insulation effect over a wide frequency range from a lower frequency to a high frequency.SOLUTION: A sound insulation structure body 1 includes a plate-like body 2, a bag body 3 as a press body which comes into partial or entire contact with an inner surface 20 of the plate-like body 2 to apply pressure, and a net body 4 serving as a retainer arranged opposite to the plate-like body 2 across the bag body 3. The net body 4 retains the bag body 3 at a predetermined position against reaction force as the bag body 3 presses the plate-like body 2. The net body 4 has a plurality of through holes. The bag body 3 presses the plate-like body 2 with pressure of a gas charged to the inside. The bag body 3 presses the plate-like body 2 and then gives the plate-like body 2 rigidity for exhibiting sound insulation performed at least in a frequency range of 10-40 Hz.SELECTED DRAWING: Figure 1
