Abstract
This article deals with the problem of the impulse response and acoustic parameters estimation of a room. The impulse response can be obtained using a clever analysis of the Empirical Transfer Function Estimate (ETFE). It is shown that the impulse response estimation is asymptotically unbiased with a bounded variance. The acoustic parameters are determined numerically from this estimation and according to their definitions. The performance of the methods is shown by an example employing a song as a test input instead of the usual pink noise. Since the method uses a reduced number of data in the input and output vectors, the computation time is reduced without significantly increasing the error with respect to the ideal response.
