A new type of hydrophone, inspired by the ears of orcas, is reportedly much more sensitive than conventional devices
Given how poorly light and radio signals are able to travel underwater, sound is still the best medium for wireless undersea communications. Conventional underwater microphones – or hydrophones – have their limitations, however. One of their main problems is that the deeper they go, the less sensitive they become. Scientists from California’s Stanford University have now found a solution to that problem, in the form of a hydrophone that is designed to perform like an orca’s ear.
