The significance of Acoustics
Noise pollution has already become a major environmental problem in our cities.
The acoustic performance of building materials will not only affect the comfort
ex- perience for us, but also has a great impact on our daily behaviors and health.
We need to pay close attention to the requirements of NR (Noise Reduction), STC
(Sound Transmission Class), RC (Reverberation time) in different application occasions for building materials. Meanwhile, the designs of architecture have to be
in according with these acoustic requirements, too.
