Pyramid foam and also other thin acoustic foams and carpets are mainly absorbing sound energy in the high frequencies, mid and low frequencies stay unaffected. This leads to a dull and muffled sound of instruments or voices.
In addition, the absorption of high frequencies is not balanced what may provoke comb filter effects. In a room with good acoustics all frequencies should be equally present. That’s why our absorbers work in a frequency range from 250 Hz up to the high end. In combination with the absorption of low frequencies by our basstraps you can design your acoustics accurately.
