Resumen
In the Netherlands there are quite a number of recently build, adjusted or to be developed buildings for large scale indoor pop events with a capacity of more than 5000 people. E.g. the Heineken Music Hall and the Music Dome are especially designed for pop music, the latter still in the process of design. Ahoy and The Amsterdam Arena are multi-purpose buildings, designed to accommodate a variety of large scale events. Designing large halls for indoor pop music is a room acoustic challenge. The music is reproduced through electro-acoustic systems; therefore a high direct-to-reverberation ratio is to be aimed at for good definition. Because of the large dimensions, the delay between direct sound en the first-order reflections is significant and reflections may be heard as echo´s if they´re too strong. A radical suppression of such reflections, also for low frequencies, is a necessity. Notwithstanding little reverberation, a homogeneous energy distribution is needed to realise sufficient loudness at any visitors´ place. In this paper problems and possible solutions to these aspects are discussed with reference to validation measurements of the Heineken Music Hall, the preliminary design of the Music Dome as well as to acoustic modifications in the Amsterdam Arena in favour of pop music.
