Abstract

This sound insulating structure ( 1 ) is provided with: a panel ( 2 ); a sound insulating material ( 3 ) laminated to the panel ( 2 ); a reinforcing material ( 4 ) provided between the panel ( 2 ) and the sound insulating material ( 3 ) and bonded to the panel ( 2 ); and an air layer (S) formed between the panel ( 2 ) and the reinforcing material ( 4 ). The reinforcing material ( 4 ) has a plurality of through-holes ( 5 ). As a result, it is possible to suppress an increase in overall weight and to secure sound shielding properties and sound insulating properties

First claim

The invention claimed is:

1. A sound insulating structure, comprising:
a panel;
