In today's homes, people go out day and back at night. Except for retired elderly people, most people have a similar daily routine. However, in recent years, a group of freelancers have emerged, such as anchor internet celebrities, stock speculators, and online store owners. These people who stay at home for a long time are mostly mental workers and are very sensitive to interference between neighbors. Compared to those who work at the company, they also create more residential noise.
Especially this year, due to the impact of the epidemic, a quiet and comfortable indoor life has become a rigid demand for almost everyone.
Quality sleep requires tranquility
Research has shown that noise is the most important external factor affecting sleep, and sleep deprivation caused by noise can seriously threaten human health, especially irregular and sudden noise. Lack of sleep can cause health damage such as insufficient rest of the cerebral cortex, weakened immunity, and brain dysfunction. During sleep, noise can cause problems such as increased arousal frequency, reduced sleep duration, fragmented sleep cycles, and decreased sleep quality.
Working from home requires quietness
There is a significant difference from daily activities such as watching TV, listening to music, and home entertainment. Working from home requires concentration and concentration, while the internal noise of the room and the activity noise between neighbors are the main interferences to working from home. These sounds are mostly sporadic and often unintentionally interrupt people's thoughts, forcing them to shift their attention and seriously affecting work efficiency.
Therefore, from the perspective of home life and office health, on the one hand, it is necessary to control the internal noise sources of the room, and on the other hand, it is necessary to improve the sound insulation and absorption effects of the walls.
Rock wool - a private sound barrier
Generally speaking, the larger the mass of a homogeneous material wall, the smaller the displacement caused by the action of air molecules on the wall, the smaller the amplitude of the wall, and the lower the amount of sound passing through. Therefore, in architectural design, soundproof materials such as rock wool are often used for filling to ensure good sound insulation and absorption effects between households.
Rock wool is a porous fiber inorganic material, with the internal air volume accounting for 90-95% of the entire surface volume, allowing air to freely enter and exit. When the air that propagates sound enters, the air molecules rub against the surface of the fibers, converting mechanical energy into thermal energy, resulting in a significant attenuation of amplitude. The macroscopic manifestation is that sound energy is absorbed and the sound level is reduced.
In addition, rock wool can also serve as a damping elastic layer for floor slabs, buffering impact strength, and thereby improving the sound insulation effect of floor slab impacts.
Creating a comfortable working and living environment from home requires technical measures such as reducing noise, improving sound insulation, and increasing sound absorption. The design standards, new materials, and management system play an indispensable role in the process of creating a sound environment.
