Abstract :
A method of measuring the mean rms level of a low duty cycle acoustic signal using an inverting circuit and an integrating digital voltmeter (DVM) is described. The technique has the capability of taking many measurements which are recorded, in one configuration, through a data coupler on paper tape for analysis on a time share computer. The important system characteristics are noted and an estimate of the system error is tabulated.
