1. Sound insulation principle
The fiber structure of glass wool enables it to effectively absorb sound waves and reduce noise propagation. When sound waves encounter glass wool, they will be reflected, refracted and attenuated between its countless tiny fibers. At the same time, part of the sound wave energy will be converted into heat energy and consumed by friction with the fibers. This process effectively reduces the propagation of sound waves, thereby achieving the effect of sound insulation.
2. Sound insulation performance
(1) Sound absorption coefficient: The sound absorption coefficient of high-quality glass wool can reach above 0.8, and even 0.9 in some frequency bands, showing excellent acoustic performance.
(2) Frequency band absorption: Glass wool has excellent absorption capacity in the mid-frequency band (500Hz-2000Hz), which can effectively reduce echoes and noise and improve sound quality.
3. Application areas
(1) Construction engineering: Glass wool is widely used in sound insulation and heat preservation of walls, ceilings and roofs, especially in places that require a quiet environment, such as offices, conference rooms, cinemas, etc.
(2) Home environment: In home decoration, glass wool is often used as a sound insulation product for walls and ceilings to help families build a quiet and comfortable environment.
(3) Industrial production: In the maintenance of industrial plants and mechanical equipment, glass wool also plays an important role. By installing glass wool, the noise during operation can be effectively reduced.
