School has started, let's talk about the acoustics design of schools

School's back in session, let's talk about school acoustic design!

Armstrong ceiling solutions Yesterday

School started, the kids are back, and learning is once again the focus of the whole family and society. So, review questions, learning machines, tutoring classes, math and English training camps...all armed!

But, do you know? As the main learning place for children, the classroom's acoustic environment will also have a significant impact on learning efficiency!

According to American research, in classrooms without acoustic design considerations, the Speech Transmission Index (STI) is only 75%! This means that students sitting in the back of the classroom may only be able to hear 3/4 of the lecture content, missing about one word for every four!

In China, research on primary and secondary school students aged 9-14 also shows that 10.7% of students cannot hear the teacher clearly, and 22.5% of students are easily distracted by the environment.

Currently, most primary and secondary school classrooms in China use concrete ceilings. Sound reflects back and forth on hard surfaces such as ceilings, walls, and floors, resulting in excessive noise and long reverberation times in the classroom, making the sound unclear and difficult to understand. Long reverberation times can also easily lead to student distraction and affect academic performance.

By selecting high-quality sound-absorbing materials, such as Armstrong high-performance sound-absorbing ceilings, it is possible to effectively reduce background noise in educational environments, absorb indoor reflected sound, and thus improve speech clarity.

In fact, with its high cost-effectiveness and convenient installation and maintenance, Armstrong mineral fiber ceiling products have become the preferred material for schools to proactively improve their teaching environment.

How about it, don't you suddenly feel "amazing"? In fact, in addition to excellent acoustic performance, our products also have high reflectivity, high moisture resistance...(500 words omitted here)...and many other excellent performances.

And most importantly, the appearance is also very high~
