High Efficiency

There are three panel thicknesses available providing different degrees of absorption (high and very high). The broadband absorption panels are highly efficient in reducing the long reverberation times, environmental noise and echoing in the office. As well, the panels are effective over a particularly broad range of frequencies and have been inspected in an echo chamber. They are certified according to DIN EN ISO 354 by the accredited Institute for Acoustics at the Lübeck University of Applied Sciences, thus acting as a guarantee of noticeable improvement in the acoustic properties of a room and in the ability to concentrate and learn.
