- I have some acoustic test data.I could'nt find a simple solution for my plotting needs.Here it goes...
- X axis have frequency values. Each X value shows a center frequency of measured octave interval. Each Y shows the overal sound pressure level at a center freq. for that interval.
Center frequencies as: 32,64,125,250,500 in Hz.
Respectively, sound pressure values are: 90,95,100,93,82 in dBP.
Y value at 125 Hz is 100 dBP, and the stair step centered at 125 Hz must extend from half octave below to half octave above 125 Hz (in this case, we'll also need a value before 32Hz and an other after 500Hz).
(X axis must show center frequencies).
