Polyester Fiber Sound - Absorbing Panels

II. The Basic Principles of Polyester Fiber Sound - Absorbing Panels

(I) Material Composition

(II) Sound - Absorbing Mechanism

1. Friction Energy Consumption
   • When sound waves enter the polyester fiber sound - absorbing panel, the sound waves cause the vibration of air molecules. There are a large number of tiny gaps between the polyester fibers, and the air molecules in these gaps will rub against the fibers. This friction will convert the energy of the sound waves into heat energy, thereby reducing the reflection of the sound waves.
2. Vibration Conversion
   • After receiving the energy of the sound waves, the polyester fibers themselves will produce tiny vibrations. Due to the elasticity and damping characteristics of the polyester fibers, these vibrations will gradually decay, and then consume the energy of the sound waves to achieve the sound - absorbing effect.

III. The Advantages of Polyester Fiber Sound - Absorbing Panels

(I) Excellent Acoustic Performance

1. Wide - Frequency Sound Absorption
   • Polyester fiber sound - absorbing panels can effectively absorb sound in a relatively wide frequency range. It has good absorption capabilities for both low - and mid - frequency noises (such as traffic noises, machine roaring sounds, etc.) and high - frequency noises (such as human voices, musical instrument sounds, etc.). In a general indoor environment, it can significantly reduce the reverberation time and improve the clarity of sound.
2. High Sound - Absorption Coefficient
   • After professional testing, the sound - absorption coefficient of polyester fiber sound - absorbing panels at specific frequencies...
