The AES Show Fall 2020 Convention Best Technical Paper Award, presented by AES Show Papers Co-chair Areti Andreopoulou, was awarded to Juhani Paasonen and co-author Ville Pulkki for their peer-reviewed paper “Short-range renderings of virtual sources for multichannel loudspeaker setups.” The paper’s abstract reads:
“A method for rendering virtual sources is proposed, where the sources are perceived to be closer than the loudspeaker array radius. The development is based on an informal finding about closer perception of the range of virtual sources rendered coherently over multiple loudspeakers. To avoid sound quality issues inherent with coherent rendering, the input is split to two streams, one with more transients and the other with smoother temporal envelope. The transient stream is rendered over coherent reproduction, and the continuous stream is processed with time-frequency-domain spreading technique. The results from localization tests with moving sources show that the proposed method produces the perception of closer distances on both sweet-spot and off-sweet-spot listening.”

The AES Show 2020 Best Student Paper Award was presented by AES Show Papers Co-chair Braxton Boren and was presented to Michele Ebri and co-authors Nicolò Strozzi, Filippo Maria Fazi, Angelo Farina and Luca Cattani for their paper “Individual Listening Zone with Frequency-Dependent Trim of Measured Impulse Responses.” The paper’s abstract reads:
“Acoustic Contrast Control (ACC) has been widely used to achieve individual audio delivery in shared environments. The effectiveness of this method is reduced when the control is performed in reverberant environments. Even if control filters are computed using measured transfer functions, the robustness of the system is affected by the presence of reverberation in the plant matrix. In this paper a new optimization method is presented to improve the ACC algorithm by applying a frequency-dependent windowing of the measured impulse response used for the filter computation, thus removing late reflections. The effects of this impulse response optimization are presented by means of sound zoning results obtained from experimental measurements performed in a car cabin.”
