Once those signals are put into an ambisonic format, the audio can be played back across a wide range of different surround sound setups. Early hydrophones were used in late World War I by submarine crews to find targets; even after sonar technology came about, hydrophone arrays helped the U.S Navy track Soviet submarine movements during the Cold War. Direct acoustic measurements in hostile environments, such as in turbojets or rocket engines, require sensors which can withstand high heat and strong vibrations. The experimental results show that the proposed microphone has the ability to detect sound waves in the whole audible range and almost omnidirectional.
