What is noise
The commonly referred to noise pollution is caused by human factors. From a physiological perspective, any sound that interferes with people's rest, study, and work, as well as the sound you want to hear, is collectively referred to as noise. When noise has a negative impact on people and the surrounding environment, it forms noise pollution.
The hazards of noise
Noise can bring great harm to students' learning and life. Studies have shown that when studying in a noisy environment, without sound insulation and noise reduction measures, students will be affected by noise interference and miss about 25% of the teacher's lecture content. Faced with sudden noise interference, people need to spend 4 seconds reorganizing their focus.
Therefore, it is crucial to create a learning environment with sound insulation and noise reduction measures, which not only makes the student's living experience more comfortable, but may also be an important condition for upgrading to a "top student".
① Sound absorption and noise reduction, improving sound quality
Rock wool has excellent sound absorption and noise reduction performance. The material itself has a noise reduction coefficient (NRC) of over 0.85, which can effectively absorb noise in various frequency bands of low, medium, and high. The pore structure of rock wool fibers can consume the energy of sound waves, reduce the transmission of noise, and make it have excellent sound absorption characteristics. Not only does it isolate outdoor noise intrusion, but it can also remove noise and improve indoor sound quality.
If silent rock wool is used in school buildings, it can reduce classroom reverberation, block the spread of noise outside the classroom, and provide students with a learning environment with clear sound quality suitable for quiet thinking.
② Fire safety, easy to construct
Compared to other sound insulation materials on the market, rock wool not only has sound insulation and noise reduction functions, but also has excellent fire and high temperature resistance, which can improve fire safety and prolong the escape time from fires.
The three-dimensional structure of rock wool fibers ensures its stable mechanical properties, making it less prone to damage during transportation, installation, and use. It can be cut freely, making it easy to install and construct, and improving work efficiency.
③ Low carbon and environmental protection, green campus
In the design of the campus, it can reflect the determination and sense of responsibility of the school to achieve carbon reduction and promote carbon neutrality. The selection of building materials also requires environmental friendliness. At the same time, by using a multi energy complementary comprehensive energy system, recyclable materials, and modular building components, the carbon footprint generated during project construction and operation is greatly reduced, making it a truly green campus.
Compared to other insulation materials, rock wool has a more positive impact on the environment and is an environmentally friendly material that is in line with sustainable development.
