Time-window differences evaluation in a room acoustic sound field diffuseness estimation

摘要

Diffusion estimation is unsolved problem, being identified in many papers for years. One of the most common problems in currently known method is impulse response time-window used for diffuseness estimation. Different methods for diffuseness estimation will be described, basing on estimation of statistical parameters like kurtosis and standard deviation with the discussion on the time-window selection and possible solutions for this problem, considering so called mixing time problem. This paper will discuss the topic of misunderstanding the term of diffuseness as room acoustic measure, being the introduction to extended diffuseness estimation in multicriteria method.
