Improvements to acoustics for major concerts Sørmarka Arena

Sørmarka Flerbrukshall IKS

Sørmarka Arena is planned to be adapted for major concerts for up to 15-20 000 persons.
Room acoustic improvements shall be carried out in the hall and measures that can make the hall more suitable.
The ceiling surface in the northern and southern halves of the hall have very different sound absorbing qualities. A sealed steel plate roof has been used in the southern end, whilst a perforated steel plate ceiling has been used in the northern end.
This gives large local variations in the sound.
This asymmetry will give an imbalance in the sound in the concert hall's breadth, which will make it very difficult to achieve any acceptable conditions in a concert situation.
In order to make it possible to achieve satisfactory sound conditions during concerts, the absorption must be increased in the ceiling surface in the hall's southern end.

DimensionsThe hall has a ground area of approx. 14 000 m2 and a total volume of approx. 177 000 m3.We envisage two possible alternatives to increase the absorption in the ceiling. These are:— Hanging up mineral wool baffles.— Direct assembly of absorbing mineral wool.For both alternatives the materials and amounts must be selected so that the sealed steel plate ceiling gets an acoustic absorption of α = 0.6-0.7 in the middle frequency area (500-1000 Hz). It is assumed that it will be sufficient to carry out the measure in the rectangular upper part of the hall. This area is dimensioned to 55 m x 81 m.In order to achieve the desired absorption, such absorbing material must be assembled in sections in a minimum of 50 % of the aera, i.e. there is a need for more than 2 000 m2 of absorbing mineral wool or similar.
