Large halls with steel structures and significant volume often struggle with the problem of excessive reverberation. Hard surfaces – concrete floors, metal roofs, or extensive technical installations – facilitate multiple sound reflections. As a result, conversations in such spaces become less intelligible, and noise easily accumulates.
