Strutt|1/3 to 1/1 Octave Level converts a row of 1/3 octave sound levels to a 1/1 octave row, which is entered into the active row of the worksheet.
Strutt prompts the user to browse for a row of 1/3 octave data to convert to 1/1 octaves, and checks to see that the selected row is a 1/3 octave row. Strutt will convert the target row into 1/1 octaves and display it in the active row. If the active row is a 1/3 octave row, then Strutt will fill in the octave band centre frequencies of the 1/3 octave row with the values.
Strutt calculates the 1/1 octave level with:
Loct=10log(100.1L1+100.1L2+100.1L3)
where Loctis the 1/1 octave level and L1,2,3 are the 1/3 octave levels.
