It is generally believed that ≤40dB is a normal sound environment that humans can bear. Above this value, it will cause harm to human health, including affecting sleep, disturbing work, obstructing conversation and hearing impairment. If you live in a noise environment of more than 80 dB, you can cause up to 50% of deafness. Noise can also lead to women's physiological disorders, menstrual disorders, increased miscarriage rate and so on. For infants and toddlers in the growing period, the noise hazards are even more pronounced. Babies who are often in a noisy environment not only receive hearing damage, but also experience intellectual development.
Textile fabrics are salty aggregates with porous, micro-vibrating elements and frictional contact points. The air in the gap acts as a low-pass filter, attenuates high-frequency sound waves or distorts the spectrum of noise, and the interface of multiple voids , The formation of sound waves back and forth reflection and vibration, resulting in internal friction, thereby reducing the intensity of noise and change the way of transmission, received sound absorption, noise reduction effect.
As an excellent sound-absorbing and sound-insulating material, textile fabrics will not directly emit sound in large quantities and cause re-contamination. Sound-absorbing wall cloths and furniture upholstery cloths can absorb sounds and purify sounds. The sound-insulating textile fabrics can not only form beautiful visual screens, but also play a role in sound insulation, noise reduction, and interference reduction. They are humans. Good protective material for the senses.
Textile sound-absorbing and sound-insulating materials, as the name implies, are composite materials that have been processed and used in the sound-absorbing and sound-insulating fields. In 2000, China's "Tenth Five-Year Plan" classified "insulation and sound insulation materials" as industrial textiles. However, in practical applications, decorative fabrics such as curtains, decorative curtains, curtains, carpets, tapestries, etc. can be used as sound-absorbing and sound-insulating materials. Since the literature was reported in 1973, textile materials have become a research hotspot in the field of sound absorption and sound insulation because of their porous structure, good processability, and light and thin materials. In the field of home decoration, there are broad application prospects in the field of automotive interior manufacturing, construction, and recording studios, stage, etc. For more information, please pay attention to China Fabric Network ()
