Abstract

PURPOSE: To know the amplitude of noise caused in the engine or body suitably and perform suitable processing after that, by the notice of the noise indicator on the driver seat by the driver.
CONSTITUTION: The noise sensor 1 uses small sized microphone and it is mounted around the noise producing source of engine or body with bolts. The noise sensor group is indicated on the noise indicator at the driver seat with the signal output cord via the selector switch 4. Normally, the noise at each is weighted totally and indicated on the noise indicator. If the amplitude of noise exceeds the range of good state, the driver reduces the engine rotating speed and running speed. Further, if necessary, the selector switch 4 is selected and the amplitude of noise in every producing source is sequentially checked to judge the production source of abnormal noise.
