Our company, in cooperation with Saint Gobain Ecophon, has renovated the most unfavourable acoustic classroom of the Fazekas Mihály Primary School and High School in Budapest. During the renovation, we achieved category A according to the Norwegian NS 8175:2012 and reduced the floor noise in the room by 6 dB. The renovation has shown that internationally excellent quality can be achieved cost-effectively even in a very unfavourable environment.
The value of the Speech Transfer Index (STI) in 70% of the room area under daytime noise conditions is above 0.75 in the case of voices without amplification.
