A multispectral multibeam echosounder may be the fruits of numerous progressive developments in hydrography through the early times of acoustic soundings when the primary problem with regard to the strength of returning echoes from the bottom was no matter if, or not, they might be adequately big to get pointed out (detected). The operating frequencies in the early acoustic sounders have been primarily determined by the flexibility of magneostrictive and piezoelectric elements whose physical Proportions could possibly be modified by the use of electrical latest or voltage.
