Read the difference between sound absorption and sound insulation materials

Example is better than words, and example is better than scenery. In daily life, school classrooms, KTV, movie theaters, recording studios and other places have used acoustic materials to optimize, a quiet environment is very important, affecting the nature of human life all the time.

What are the differences between sound absorption and sound insulation materials?

Sound absorption refers to the use of sound absorption materials or sound absorption structure, the intake of sound energy absorption and consumption, compared with the smooth wall, the sound will be smaller, but more real and clear. The more sound-absorbing material you use, the more obvious the effect will be. Carpets seen in hotels, wall tapestries and other decorations, as well as soft bags used in decoration, all provide a sound-absorbing effect to the space. This is why some restaurants are not big, but people feel noisy when they talk, and they need to be very loud to let others hear their voice. Although some restaurants are toasts, but sitting inside it feels not noisy, and communication with others is very easy.

Sound insulation is the use of sound insulation structure to block the sound, reduce the transmission of noise, so that the noise environment and the need for quiet environment separated. Your voice may sound just as loud in your ears as it did before, but you can't be heard in the next room.

In terms of the use of materials, sound-absorbing materials are mostly fluffy and porous materials, while sound insulation materials are mostly dense and breathable materials.

For environments that are noisy and have a need for sound control, especially KTV, cinemas, theaters, schools, etc., it is often necessary to use sound-absorbing materials to reduce the noise in the space while strengthening sound insulation to enhance the comfort of the acoustic environment.
