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.
