Sound Absorption Performance of the Poplar Seed Fiber/PCL Composite Materials. [PDF]
Materials (Basel), 2020 Composite materials were prepared by the hot pressing method using poplar seed fibers and polycaprolactone (PCL) as the raw materials to solve the problems related to the recycling of waste fibers. The effects of mass fraction of poplar seed fibers, the volume density, and thickness on the sound absorption performance of the resulting composite ...

Investigation of Sound Absorption Performance of Roof Panels in Automobiles
International Journal of Mechanical Engineering, 2022 Vehicle interior noise is a factor that directly affects users' perception of the quality of passenger cars. Research shows that there have been more focus on NVH (Noise, Vibration, Harshness) studies in modern vehicles in recent years. Ceiling tiles are extremely important in controlling vehicle interior noise.

Variability and Performance Study of the Sound Absorption of Used Cigarette Butts [PDF]
Materials, 2019 There has been increasing interest in new sustainable materials that can be used as construction materials. Among them, sound-absorbing materials have an important role in both acoustical room conditioning and in room insulation. As a proposal for recycling, one of the most common residues in the world, cigarette butts, is studied.
