7. FREQUENCY CHART
In order to maintain a better survey only every second value is registered in the table. The adjustable values do
not exactly fit into a 1/60 octave intervall, because also the ISO frequencies do not perfectly fit into a physical
1/3 octave intervall. Rather a linear approximation is used to specify the values.
