The 2014 refurbishment works in the building attributed special importance to improving the acoustics of Pesti Vigadó's Ceremonial Hall: improved acoustic quality was confirmed not only by acoustic measurements but also by performers' appreciative feedback. Above the mobile stage, a theatre engineering baldachin, incorporating both mobile plexiglass sound boards and work lights for the musicians, was constructed, which can be lifted to the desired height by using an electric fly line system. The fine-tuning of the Hall's acoustics is made complete by the use of mobile boards, which can be used in several ways befitting the needs of the musical production in question.
