The amount of recorded sounds between both EARs is different, they are however highly correlated (rs = 0.45, p <0.001) and follow the same trend in activity in the course of the whole period.
Fjöldi hljóða var mismunandi milli hljóðnemanna (eyrnanna tveggja, EARs), en hins vegar var marktækt samband á milli þeirra (rs = 0,45, p <0,001) og samskonar ferill reyndist í virkni þeirra á rannsóknartímanum.
