For one of the concert halls there was an internet questionnaire sent out to musicians who have performed in the hall but for the other concert hall the questionnaire was simultaneously laid out for a group of choir singers present in the hall.
Fyrir annan salinn var sendur út vefspurningalisti til tónlistarfólks sem hefur notað salinn en fyrir hinn salinn var könnun lögð samtímis fyrir hóp af tónlistarfólki sem var á staðnum.
