✦ Synopsis
Bjergsted concert hall in Stavanger, Norway, was opened in 1982 as a multi-purpose hail, but primarily intended for concert~'. The hall has been rebuilt frem an oM dome-shaped exhibition hall. The new shape qf the hall was designed using computeri:ed sound ray tracing, in a threedimensional mathematical model. The hall i~ fan-shat)ed and additional lateral reflections are pro~'ided .by large reflectors hanging freely below the ceiling. Because of the marginal voh,ne per seat ~,nd the hall's man), light-weight con.~tructions, we have designed, .~pec(ficL,41)' for this hall, an clectroacoustic multi-channel ret'erheration '¢)'stem. This increases the reverberation time over a broad frequency range and, in addilion, the sound lerel is also increased.
