Improvement for every step

Whereas sound absorption describes the acoustic situation inside a room, impact sound insulation concerns sound between adjacent rooms, in particular sound transmitted to rooms below. Measurement is made according to ISO 140-8.

Impact sound occurs when people walk on floors and stairs, but also when furniture or other objects are moved across the floor for instance. This noise can then be perceived clearly by those in adjacent rooms if insulation is poor. Carpets meet the statutory requirements for building projects without any special measures for fitting or additional insulating underlay. As a result, they contribute to an increased feeling of comfort and to greater concentration, and thus noticeably improve the working atmosphere. Noise is still one of the main causes of reduced efficiency in the workplace with, to some extent, adverse consequences for health.

Impact sound insulation indicates, in dB, how much a floor covering (as compared to the standard bare concrete floor) improves the values. With carpets it is possible to achieve values of 22–31 dB here without difficulty, whereas values for hard flooring are only between 4–10 dB without accessory fittings. An improvement of 10 dB in impact sound insulation means half the level of noise.
