NOISE MEASUREMENT USING GPS

摘要

A method and a system for measuring noise using a GPS is provided to measure the underwater radiation noise with respect to a measured ship by calculating three-dimensional position information in real time. A system for measuring noise using a GPS includes a sound listening section, a cable(170), an ultrasonic transmission section(150), a sound listening information receiving section, and a distance calculating unit. The distance calculating unit calculates three-dimensional position information of a plurality of sound listening units on the basis of an ultrasonic signal radiated from the ultrasonic transmission section and calculates the distance from a measured ship to the plurality of sound listening units.
