Noise testing method for motor vehicle, involves determining measurable factors, which are objective to noise, where each factor is multiplied with constant regression coefficients determined by uniquely performed audiometry
The method involves determining measurable factors e.g. loudness or throatiness, which are objective to noise. Each factor is multiplied with a constant regression coefficient, and products are added with each other to a comparative figure, which represents a quality rating of the noise. The regression coefficients are determined by a uniquely performed audiometry. A constant is added to the comparative figure for correction, and the factors are ignored when the regression coefficient is very small.
