Acoustical Measurement Uncertainty for the Underwater Sound Reference Division in the Frequency Range of 3 Hz-to-1.6 kHz in Simulated Oceanic Environments

Abstract

This report documents the uncertainty in the primary and secondary calibration of hydrophones between 3 Hz and 1,600 Hz in simulated oceanic environments at the Underwater Sound Reference Division (USRD), the National Institute of Standards and Technology (NIST) Designated Institute (DI) for acoustics: sound in water. After an overview of uncertainty estimation and propagation methods, the equipment and measurement theory for the primary coupler reciprocity calibration and secondary standing wave tube comparison calibration are described and their uncertainties developed. Sources of uncertainty are discussed in detail. Tabulated results show the combined expanded uncertainties for primary and secondary calibration of hydrophones.
