The NBS conical transducer is a sensitive, broadband device for the measurement of surface displacement as a function of time. Its uses include acoustic‐emission testing. Here, the operation of this transducer is subjected to a straightforward anal

We have set up and are using an apparatus for the measurement of total sound power output of a piezoelectric transducer radiating into water. This apparatus combines the better features of previously used methods which depend on radiation pressure. T

A method for obtaining the signatures (waveforms) of certain acoustic emission events has been developed. The waveform is that at the source, free of contamination by ringing of the specimen, apparatus, and transducer. The technique is based on the c

We have constructed a capacitive transducer for the absolute measurement of the normal component of surface‐wave motion on a flat solid, the direction of travel of the wave being known. The transducer backplate is a cylinder and has cylindrical ext

Those results of the theory of the baffled, uniform‐piston radiator that can be calculated exactly are extended to some other cases, especially the simplest case of a simply supported radiator, the simplest case of a clamped‐edge radiator and a G

Neutron thresholds at various temperatures were measured for methanol, ethanol, 1-propanol, 2-propanol, n-pentane, diethyl ether, fluorocarbon 113 and fluorocarbon 11, and fission thresholds were similarly measured for water, 1-propanol and 2-propano

The anomalies in the audiofrequency compliances reported by Fitzgerald [J. Acoust. Soc. Am. 32, 1270 (1960)] were searched for in vain. In particular, the measured shear compliances were independent of frequency and prestress within the experimental
