1/3 to 1/1 Octave Band Loss

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.
