The method of mapping of acoustic field, emitted by sources of sound in the environment, with implementation of the MEMS IMU unit and laser devices

During the course of the research, a methodology of measurement of sources of noise was developed, along with measurement models and measurement sets. The latter were equipped with microphones, acoustic pressure level meters, devices determining spatial orientation of the measurement (laser rangefinder, inertial measurement unit 3D IMU) and software processing the data, obtained including final spatial mapping of the acoustic field. The system has been successfully tried in large indoor areas.
