Array loudspeakers

The new PA system with 20 line array loudspeakers in the main hall of Copenhagen central Railway station has been modelled with Odeon. The hall is about 190000 m3 and has a reverberation time of 4 s. The loudspeaker installations were made in collaboration with Duran Audio and AV-huset.

[1] It is a challenge to achieve resonable speech intelligibillity in this large main hall with a reverberation time of 4 seconds. To see the achieved STI press next through this case-story. You can also listen to the auralisation with the 20 array loudspeakers by scrolling further down this page.

Below you find 3 multisource auralisation examples which illustrates how the system sounds in a central position (receiver 14) with ambient noise. 1 for a person speaking, 2 with only a remote array loudspeaker and 3 with the total designed array loudspeaker system. The 3 examples are also presented in this interview by the naked scientists.
