This paper presents a new measurement method for the measurement of the short reverberation time of a car compartment. The method is applied to the measurement of reverberation time of a compact size passenger car. The new method is based on the modified wavelet transform for the transient sound signal obtained inside of a car. The measurement error due to a small Bandwidth-Time product (BT) is reduced by using a new method.
