SONIUM® achieves very high sound absorption particularly at low frequencies without using combustible or conventional fibrous materials. The sound absorption properties are remarkable for such a low weight and fibre free material. Able to reduce interior noise and improve interior acoustic quality, the peak absorption
frequency of SONIUM® can be tailored to the frequency range required, simply by selecting an appropriate panel thickness. SONIUM® is faced on one side with a corrugated micro-perforated aluminium sheet (SONIUM | CORR).
