Acoustical Measurements for Automotive Sound System Evaluation Using Time Delay Spectrometry 890119
Over the last few years significant emphasis has been placed on the design of automotive sound systems having proper spectral and spatial performance. But often the frequency response of such a system is subjectively perceived as unbalanced. This paper investigates the direct sound field's frequency response in the car and the effect of the early reflections upon the total sound field. In-car acoustics and subjective test methods are discussed as well.
