The sound-absorbing material acts by
reducing the reverberation time (i.e. the
time required to reduce any noise inside
the room by 60 db, so as to ensure that
any echoes due to reflections on the walls
are inaudible).
The frequency of human voice typically
ranges from 1 to 4 kHz.
The use of materials capable to
reduce these frequencies allows better
understanding of speech and prevents
the need to talk loudly to cover the
background noise.
The sound-absorbing appliance should be
located 400-600 mm off the ceiling to
ensure optimal operation.
