Abstract
A transducer assembly for attachment to a marine device for use in marine seismic applications. The transducer assembly includes an attachment portion attachable to the marine device and a transducer portion attachable to the attachment portion. The attachment portion is fabricated with a relative larger diameter and of a first material selected for strength, while the transducer portion of the transducer assembly is fabricated with a relative reduced diameter of a second material selected to minimize interference with acoustic signals propagating to or from the transducer portion. The reduced diameter of the transducer portion reduces the incidence and magnitude of drag during the marine seismic applications and minimizes the negative effects of drag on the results of the marine seismic application. The second material of the transducer portion is selected to have an acoustic impedance that minimizes interference with the operation of a transducer positioned within the transducer portion.
