Energy Spectrum Levels of the Thumper Transducer.
Abstract
An impulse type acoustic transducer to be operated as deep as 10,000 ft is a particular need for some of our experiments. The 'thumper' source (on load from WHOI) appears to be worth looking into for this application. The basic data available for this purpose is in the form of three photographs of a CRO presentation of the thumper pulses received by a hydrophone 6ft below the transducer. In order to compute the spectrum of the main pulse, it has been measured and approximated by curve fitting. The spectrum of the pulse is computed by taking its Fourier transform.
