Strutt|1/3 to 1/1 Octave Loss converts a row of 1/3 octave sound losses 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 can convert both positive sign convention and negative sign convention losses using this feature.
Strutt calculates negative 1/1 octave losses with:
Strutt calculates positive 1/1 octave losses with:
where Roct is the 1/1 octave loss and R1,2,3 are the 1/3 octave losses.
