What is Soundproofing
What is "sound absorption"?
It is the function of absorbing the generated sound and not reflecting it back. If, on the other hand, the sound passes through to the other side, the sound will end up being transmitted.
What is "sound insulation"?
It is the function of bouncing and reflecting the sound. Conversely, if the sound does not pass through to the outside, the sound will echo inside.
Wanting to lessen the echo of a room. (Glass wool, rock wool, etc.)
What is "vibration isolation"?
It is the process of lessening the transmission of vibrations as much as possible so that it is not communicated.
