What kind of carpet can you buy to absorb sound and sound?

The above picture is a picture released by the international carpet industry at the 20 13 International Floor Paving Material Exhibition in Hanover, Germany. These pictures fully show the characteristics of carpets.

The soft floor material of the carpet does not vibrate when walking on it, but the sound is transmitted by vibration, you know? Since there is no vibration, where is the sound?

Generally speaking, it is not to absorb sound, but to prevent the spread of sound.

Why do hotels have to use carpets? At least there should be carpets in the corridor, because one of the hotel tests is noise detection, otherwise it will not pass.

Remember, this is a carpet.

Don't make textiles, like non-woven "red carpet", which has nothing to do with carpets. Don't just pay attention to the price, cheap goods are not good.

In fact, carpets are not more expensive than hard floors. Generally speaking, they are almost the same.
