Table III.

Means ± standard deviations and coefficients of variation (COV = standard deviation / mean, in parentheses expressed as a percentage) for acoustic pulse parameters for hydrophones obtained using the traditional scaling method (“Scale”), the traditional scaling method plus low-pass filtering (“Scale+LPF”), and using deconvolution based on the magnitude of the sensitivity (“Mag”), the direct measurement of the complex sensitivity (“Direct”), and the minimum phase estimate of the complex sensitivity (“MP”).
