Sound Acoustic Solution
Acoustic Material
Sound Acoustic Solution mechanism by porous material.
Gaps are important, not frames.
Increases internal loss of material by narrowing gaps.

To reduce the size of the gap to increase loss
- Decrease porosity (increase the number of fibers)
- It is not preferable because it increases the weight of non-woven fabric.
What happens if the fibers are made finner if the non-woven fabric weights the same?
The number of fibers increases
The gap becomes smaller (it becomes difficult to ventilate)
