A comparison of two impact noise measurement techniques.
An impact noise analyzer has been tested to determine its accuracy and precision. Results showed that peak estimation when corrected by a suitable correction factor were good and the confidence limits on the corrected peak determination were less than +/- 1.0 dB. Determination of pulse duration with the meter proved to be poor. At present it is useful for making only general estimations of duration. For exact pulse duration measurements, it appears that development of a small, portable oscilloscope holds the most promise for a field instrument with the necessary accuracy and precision.
