demand high acoustic sensitivity as well as broadband performance. The acoustic performance of such transducers - ex- tremely low-ringing, large bandwidths, low Q ratings, and reduced sidelobes - are preferred. Applications: Single & Multi-Beam Sonar; Acoustic Backscat- ter; Acoustic Doppler; Hydrographic Survey; Custom ConÞ gurations; Inter- ferometry; Fisheries Research; CHIRP Sonar; Underwater Modem; Parametric; Hydrophones.Applied Acoustics Marine House, Marine Park, Great Yarmouth Norfolk NR31 0NB, UK Tel: +44 1493 440355 Email: [email protected]://www.appliedacoustics.com CEO: Adam Darling Marketing Director: Sue Meeken Sales Manager: Gavin Willoughby Engeneering Director: Neil MacDonald Number of Employees: 40 Applied Acoustics designs and manu- factures high tech subsea positioning transponders, USBL underwater track- ing systems and sub-bottom proÞ ling equipment. The company, founded in 1989, initially supplied equipment to the O&G sector, but now supplies its products to oceanographic institutions and defense industries in addition to its traditional offshore survey customers. Heavy investment in R&D results in a steady stream of new products to in- crease operational efÞ ciencies, includ- ing the Nexus Easytrak, fast becom- ing the generic name for USBL subsea tracking, and the S-Boom, a novel 3-plate high power synchronised sound source to improve resolution and pen- etration during shallow water geophysi- cal surveys. The higher penetration, high resolution proÞ les obtained from the S-Boom have resulted in superior results during nearshore wind farm site surveys.
