MULTICHANNEL VIBROACOUSTIC SYSTEM OF SIMULATION AND REPRODUCTION OF AIRCRAFT NOISE FOR AVIATION SIMULATORS (VERSIONS) AND METHOD OF SIMULATING AND REPRODUCING AIRCRAFT NOISE (VERSIONS) Russian patent published in 2016 - IPC G09B9/22 

FIELD: aircraft; training means.

SUBSTANCE: group of inventions relates to methods and systems of simulation and reproduction of aircraft noise for aviation simulators. Multichannel vibroacoustic system of simulation and reproduction of aircraft noise comprises front and rear speakers arranged in a certain manner. To simulate and reproduce aircraft noise for aviation simulators from a library of vibroacoustic records obtained beforehand from onboard an aircraft in the form of samples fixed for the respective note piano keyboard are extracted mixed, subjected to parametric adjustment and editing, transmitted are the said samples in independent from each other form through a MIDI sequencer in accordance with a MIDI script positioning each sample starting time onto physical outputs of the playback system in a certain manner, and the reproduced sum of all samples is corrected relative to reference signals.

EFFECT: provided is accuracy of reproduction and simulation of acoustic noise produced by technical assemblies and units of the aircraft.
