PURPOSE: A noise alarming device of a car enables a driver to correctly check a bad maintenance, thereby decreasing a noise. CONSTITUTION: A noise alarming device comprises sealed parts, noise measurement sections(100), a memory section(20), an engine control section(10), an indication section and an alarm driving part. Sealed parts seal up noise generating parts of the car with a soundproofing material to decrease a noise. Noise measurement sections(100) disposed at each sealed part measures the noise and outputs an electric wave level. The engine control section(10) inputs a noise measurement level signal outputted from noise measurement sections(100), and checks the condition of sealed parts and the maintenance of the car. Therefore, the noise alarming device enables a driver to check a maintenance condition, thereby previously preventing an accident due to many troubles.
