Abstract
An improvement for an apparatus for calibrating or otherwise determining low frequency operational parameters of an elongate hose-like array is compact enough to be mounted on a cart-like member which is free to travel the length of the array. The improvement is in the form of a pair of oppositely extending tubes each having a reciprocating element for ensonifying selective portions of the elongate array with low frequency energy. Having the reciprocating elements 180.degree. moving out of phase with respect to one another to exhibit mirror image excursions and at least one flexible radiating surface proximately located to the array assures that performance compromising vibrations are nullified and that low frequency energy is responsively received by the individual transducer elements along the array's length.
