Real-time noise source visualizing system using acoustic mirror
First Claim
1. A noise source visualizing system used in a wind tunnel test to measure generated sounds, the system comprising:
- an acoustic mirror for converging sound waves of sounds generated on a surface of a vehicle during a wind tunnel test;
a microphone mounted at a position where the sound waves are converged by the acoustic mirror, the microphone measuring the converged sound waves;
an image-photographing unit mounted to one side of the microphone and which photographs locations on the vehicle at which the sounds are generated;
a first display unit mounted to a distal end of the image-photographing unit, and which performs display of the sounds measured by the microphone as colors that vary according to characteristics of the sounds;
a traverse to which the acoustic mirror is connected and which is mounted near a side of the vehicle, and which is able to move up and down and along a length of the vehicle to positions for enabling the acoustic mirror to collect the sounds;
a workstation for analyzing the converged sound waves measured by the microphone, the images photographed by the image-photographing unit, and the signals displayed through the first display unit; and
a second display unit overlapping then displaying image signals photographed by the image-photographing unit and the colors displayed on the first display unit.

Abstract
Disclosed is a noise source visualizing system used in a wind tunnel test to measure generated sounds, the system comprising an acoustic mirror for converging sound waves of sounds generated on a surface of a vehicle during a wind tunnel test; a microphone measuring the converged sound waves; an image-photographing unit photographing locations on the vehicle at which the sounds are generated; a first display unit displaying the sounds measured by the microphone as colors that vary according to characteristics of the sounds; a movable traverse to which the acoustic mirror is connected for enabling the acoustic mirror to collect the sounds; a workstation for analyzing the converged sound waves measured by the microphone, the images photographed by the image-photographing unit, and the signals displayed through first display unit; and a second display unit overlapping then displaying image signals photographed by the image-photographing unit and the colors displayed on the first display unit.
