The survey is carried out by way of a nationwide panel which is equipped with electronic measuring apparatuses that recognise all radio sound transmitted from the participating radio channels. Only radio channels taking part in the survey is monitored, and results may vary depending on the number of channels participating. Timeshift listening - including podcasts - until 7 days after broadcast is included.
The main changes to the survey layout after Nielsen took over from Kantar i 2019 are: More NRKs channels are included, the panel is twice the size as the previous one and the lower age limit has been reduced from 12 to 10 years.
