Abstract
Modern telepresence systems constitute a new challenge for quality assessment of multimedia signals. This paper focuses on the evaluation of the reverberation impairment for audioband speech signals. A review on the reverberation effect is presented, with emphasis given on the mathematical modeling of its components, including early reflections and late reverberation. A subjective test for evaluating the human perception of the reverberation phenomenon is completely described, from its conception to the final results. Analyses are provided comparing the average subjective grades to current quality-evaluation standards for speech and audio signals. It is verified how the reverberation perception can be mapped onto three main system characteristics: reverberation time (associated to the room acoustical properties), source-microphone distance, and room volume. Direct estimation of these parameters from the room impulse response is discussed. One established reverberation measure is then revisited in the audioband speech context, showing high correlation with the subjective grades previously obtained.
