Parameter Estimation for the NPRQ-Measure with Sub-Sample Precision


Sounds played in closed rooms often suffer from added reverberation. For reducing these effects, the methods of room impulse response equalization may be employed. In order to render the echoes inaudible at a given position, a prefilter is used to modify the played signal. This pre- filter is designed according to the properties of the human auditory system, such as temporal masking. Typically, the average temporal masking curve is used to describe the audible reverberation in terms of the nPRQ-Measure and to derive the cost function for the filter design. In this work, we propose to estimate the parameters of this curve with sub-sample precision in order to achieve a better estimation of the perceived reverberation. This higher precision is necessary for comparing the results in case of spatial mismatch.
