What does soundproofing mean with reference to a raised floor performance ?
A raised floor must not cause unpleasant noise when in use. The top finish is the most important element with reference to sound level in a room; another factor is the height of the structure. On the other hand, the more the panel is thick and dense, the more the soundproofing improves. Therefore, the sound level varies according to three factors: Panel density Type of top finish Height of the structure The ISO Norm No. 140 expresses, by testing at 500 Hz, the resulting dB values. Any estimate of the soundproofing level of a raised floor must refer to test data relating to the same height of structure with the same top finish.
