Hydrophone calibration by the substitution method using pseudo-gaussian white noise / C. Hodson, G.W. McMahon ; approved by R.A. Kendall. : D68-21/1-1976E-PDF
"A computer-based procedure has been developed for calibrating hydrophones by the substitution method using a pseudo-gaussian white noise signal. The technique has been shown to be a viable alternative to the more conventional CW and pulsed CW substitution methods. Owing to the wideband nature of the noise signal, the effects of boundary conditions are reduced considerably. Software routines for a Honeywell H-316 minicomputer are used to generate the noise signal, perform the analog-to-digital sampling and carry out the calibration computations. This method is particularly useful for low frequency wideband calibration and would allow measurement to less than one Hertz"--Abstract, page ii.
