Division 3.3 Calculation of the linear sound level increase expected for each measurement

The sound level L_ASEP,kj for measurement point j and gear k shall be calculated using the engine speeds measured for each measurement point, using the slope specified in point 3.2 to the specific anchor point for each gear ratio.

For n_{BB_k,j} ≤ n_anchor,k:

L_{ASEP_k,j} = L_{anchor_k} + (Slope_{k – Y}) * (n_{BB_k,j – nanchor,k})/1 000

For n_{BB_k,j} > n_anchor,k:

L_{ASEP_k,j} = L_{anchor_k} + (Slope_k + Y) * (n_{BB_k,j – nanchor,k})/1 000

Where Y = 1
