Fiberboard is a lightweight, low-fiber board that can be used for sound insulation.
It is commonly used to provide sound insulation for exterior walls, but it can also be used to soundproof rooms.
In a new study, researchers from Carnegie Mellon University and the University of Texas at Austin, found that fiberboard can be very effective for sound protection.
The research, which is detailed in the March issue of ACS Nano, found fiberboard outperformed conventional soundproof materials.
The researchers also found that the sound barrier effect is stronger in fiberboard than in other materials tested.
“In this study, we demonstrate that fiberboarding can be soundproof and provide a sound barrier to the outside environment,” said lead author Jana Fagan, a doctoral candidate in electrical engineering and a graduate student in the department of electrical and computer engineering.
“This finding is a huge step forward for sound-proofing applications.”
The researchers tested four materials in the soundproof test room, which they say provides an ideal environment for testing.
They used a combination of fiberboard and other soundproof panels to simulate the sound pressure level of a room.
The materials tested included copper-nickel-plated and stainless-steel soundproofers and insulated with fiberboard.
The soundproof tests were done with two different materials: fiberboard plenums and aluminum-nickeled boards.
Fiberboard plenfiers, which are commonly used in soundproof windows, can be hard to detect and can also lead to audible leakage, which can cause headaches.
But fiberboard is much harder to detect because of its thinness and it can be easily removed.
“The fiberboard soundproofs do a great job at absorbing sound,” Fagan said.
“But, in our test, we found that there is some leakage.
That leakage can cause the sound to become louder when the sound is coming from outside.”
To measure the sound absorption, the researchers used a sound-absorbing mic placed above the fiberboard panel and connected to a sound detector.
The mic would pick up the sound and compare it to the sound from outside the room, with each measurement made once every 10 seconds.
They also measured the difference between the sound coming from inside the room and outside.
The results show that fiberboards soundproofed sound at a very high level of sound absorption.
“Our results show soundproof sound is much better than soundproof, but fiberboard doesn’t sound like it,” Faggan said.
The study also found fiberboards outperformed other soundboard materials, such as copper-plating boards, aluminum-plates and stainless steel, when it came to noise-reduction.
The fiberboard-based materials had the same sound barrier performance as copper plating boards and aluminum plating panels, the authors said.
