SONOTEC® ACOUSTIC PANELS
Sonobex has pioneered the development of a patent protected* and award winning acoustic panel technology, called SonoTEC®, using our understanding of acoustic metamaterials.
SonoTEC® panels are based upon a metamaterial structure that incorporates an array of identical mechanical resonators. Adjacent resonators interact and couple with each other to create broad bands of attenuation at targeted frequencies, including difficult low frequencies.
With superior low-frequency performance, specifically targeted for power transformers, a SonoTEC® panel achieves up to 34 dB attenuation for 100 Hz tonal applications, with an absorption coefficient of 1.13, whilst maintaining high transmission loss at higher frequencies, Rw (C:Ctr) = 44 (-1;-2 dB).
