As an acoustics specialist with wide-ranging experience, how would you define the concept of impact noise reduction?

Impact noise reduction is related to a floor covering that ensures higher insulation from impact noise, in accordance with ISO 10140-5. This is defined as the reduction of impact noise pressure levels, measured in the recipient room after installation of a floor covering on a 140mm thick reinforced concrete floor.

Acoustically absorbent wall covering system

This compound is then heated, pressed into a mold and cut into sheets.   The combination of cork backing with wool felt creates a durable and acoustically absorbent wall covering system. Although there are different variations, in function of the models, the coverings register noise reduction coefficients (NRC) of up t…

Acoustic Performance

Reduction of noise transmission can reach levels of 5 to 12dB (across the frequency range up to 5kHz) compared to conventional flooring systems and depending on the Alucork construction type. Overall when considering the soundproofing per unit of mass (dB / kg), Alucork distances itself from any system known, making it…

Eight years ago (2009), we were thinking about what we could do better to offer to the end consumer and we found that we should offer something more quiet, comfortable and warmer. In this respect, we could provide these features by including cork in our wood floors. We thought about how to get layers to include in our…
