Abstract
Having an accurate statistical model of room impulse responses
with a minimum number of parameters is of crucial
importance in applications such as dereverberation. In this
paper, by taking into account the behaviour of the early reflections,
we extend the widely-used statistical model proposed
by Polack. The squared room impulse response is modelled in
each frequency band as the realisation of a stochastic process
weighted by the sum of two exponential decays. Roomindependent
values for the new parameters involved are obtained
through analysis of several room impulse response
databases, and v
