5 ACOUSTICS Performance Hall Aimed T30 values / The generally acceptable values for Reverberation time (T30) at 1 khz for music halls range from 1.4 to.4 seconds. The Reverberation time in Oslo Opera House is 1.7 seconds [Stand, 008, p.180]. DR concert hall has a reverberation time of 1.8 to.4 seconds. DR Orchestra hall, similar in size to the Music House s performance hall, has a reverberation time varying from 1.1 to 1.7 seconds [ 11 March 09]. Therefore the aimed reverberation time is from around 1.6 seconds. Results of CATT Acoustics model / The demo version of CATT only allows for half the recommended amount of sound rays (1000 rays) for audience area mapping (to determine the SPL distribution), therefore the prediction is less reliable. Changes in the outcome value occurs because the limited amount of rays are sent along varying paths each time a calculation is made. An average of values for T30 and D50 can be seen in [174]. SPL distribution / The sound pressure level distribution is very even along a majority of the audience plane in the hall, with the exception of a few areas with a lower SPL. Echo / This is only heard if the sound is heard more than 50ms after the original sound, otherwise the echo actually strengthens the sound. [176] shows sound reflections over time. It is important that the first sound lines occur within 50 ms, which can be seen here. Therefore echo is not detected.

7 8 Rehearsal Areas The reverberation time (T30) required for the rehearsal rooms ranges from 1. to 1.6 seconds. The value is are slightly lower than that of the Performance Hall due to its smaller volume and amount of users playing music. [Egan, 007, p.64]. Sound pressure level (SPL) distribution should be less than 10dB in sound difference. Deutlichkeit (Clarity, D50) should be over 40%. To achieve these values, a combination of the following materials are used. Materials accompanied by images contribute to the aesthetic expression of the rooms. Values were taken from [Egan, 007, p.p.5-53], [Bies & Hansen, 1988, p.p ], [ Absorption Coefficients for each material are listed according to the following sound frequencies (Hz): < 15 Hz 50 Hz 500 Hz 1000 Hz 000 Hz 4000 Hz > Regular wall materials / Glass < > Plywood 19 mm Panels with airspace More absorptive < > Plywood 5 mm Panels with 50mm airspace More absorptive < > European Oak Hardwood Translucent Acoustic Glass Translucent wooden panels offset from normal glass Plasterboard walls 1 mm < > < > < > Varying hardnesses of wooden floors make a significant change in the acoustic quality of a room.

Floor slab / To reduce impact sound the following is installed: 5 mm wooden floor on joists and rubber 60 mm insulation 100 mm insulation Air gap 100 mm insulation The outer walls are clad with cedar panels and appear in three different ways: - Solid - Transparent - Translucent, every other wooden panel is removed This meets the standard for the reduction of impact sound for rooms of high noise levels (39 db). Furthermore it meets the standard for reducing transmission sound (60 db). Transparent glass wall / Transparent walls are used in the rehearsals rooms. To reduce transmission sound, double layered acoustic glass is installed: 40 mm acoustic glass 0 mm air gap 40 mm acoustic glass This gives a sound reduction of at least 50 db.
