MOUS_ICO Menu: Noise > Calculation points > Add 3dBA

Adds 3dBA to the noise values for the current alternative for all active calculation points. The addition is added to both Lequ, Lnight, Lmax, and Lden. The contribution from reflection is set to 3dBA.

Note: This function is only meant for completely exceptional cases and implies the risk of some pitfalls:

• This is a “one-time-only” function, not a setting that makes the program “remember” that these points should have an addition. If one recalculates these points, one possibly has to call this function again to add 3dBA once more.
• If one has calculated including reflection, this addition comes “on top”.
• The contribution from reflection is set to 3dBA. If one has calculated including reflection and has gotten e.g. 2dBA in contribution from reflection, after having run this function one will have included a total of 5dBA reflection in the values for, e.g., Lequ, while the given value for contribution from reflection will be 3dBA.
• If this function is run several times, 3dBA will be added each time, while the given contribution from reflection still stands as 3dBA.
